How can I uninstall Ruby on ubuntu?

Somehow I&#39;ve managed to completely bugger the install of postgresql on Ubuntu karmic.  I want to start over from scratch, but when I &quot;purge&quot; the package with apt-get it still leaves traces behind such that the reinstall configuration doesn&#39;t run properly.

After I&#39;ve done:

    apt-get purge postgresql
    apt-get install postgresql

It said

    Setting up postgresql-8.4 (8.4.3-0ubuntu9.10.1) ...
    Configuring already existing cluster (configuration: /etc/postgresql/8.4/main, data: /var/lib/postgresql/8.4/main, owner: 108:112)
    Error: move_conffile: required configuration file     /var/lib/postgresql/8.4/main/postgresql.conf does not exist
    Error: could not create default cluster. Please create it manually with

      pg_createcluster 8.4 main --start

    or a similar command (see &#39;man pg_createcluster&#39;).
    update-alternatives: using /usr/share/postgresql/8.4/man/man1/postmaster.1.gz to provide /usr/share/man/man1/postmaster.1.gz (postmaster.1.gz) in auto mode.

    Setting up postgresql (8.4.3-0ubuntu9.10.1) ...


I have a &quot;/etc/postgresql&quot; with nothing in it and &quot;/etc/postgresql-common/&quot; has a &#39;pg_upgradecluser.d&#39; directory and root.crt and user_clusters files.

The /etc/passwd has a postgres user; the purge script doesn&#39;t appear to touch it.  There&#39;s been a bunch of symptoms which I work through only to expose the next. 

Right this second, when I run that command &quot;pg_createcluster...&quot; it complains that &#39;/var/lib/postgresql/8.4/main/postgresql.conf does not exist&#39;, so I&#39;ll go find one of those but I&#39;m sure that won&#39;t be the end of it.

Is there not some easy one-liner (or two) which will burn it completely and let me start over?


How to thoroughly purge and reinstall postgresql on ubuntu?

This question may look like a duplicate of: https://stackoverflow.com/questions/2715055/how-to-uninstall-postgresql-on-my-mac-running-snow-leopard however, there are two major differences. I&#39;m running Lion and I&#39;m trying to uninstall PostgreSQL 9.0.4. I&#39;ve looked at the last question and the link that it referenced, but I did not find a file called &quot;uninstall-postgresql&quot; when I run this command:

    sudo find / -name &quot;*uninstall-*&quot;  

So, I assume this means that the uninstall process for 9.0.4 is different than that of 8.x.

I&#39;ve seen a couple of posts in different places describing a method for manual uninstallation but, similarly, some of the directories/files referenced are not present on my machine.

Any assistance or direction you can provide would be greatly appreciated.

Just for reference, this is the link the other poster used to uninstall postgres from snow leopard. As I tried to step through these commands, most of them choked with some variant of &quot;command not found&quot;.

UPDATE:

In addition to `brew uninstall postgres`, should I remove any of the following files/directories manually? Keep in mind I want to completely wipe the slate clean, no data files/database tables or anything.


    &gt; sudo find / -name &quot;*postgres*&quot;

Completely uninstall PostgreSQL 9.0.4 from Mac OSX Lion?

How do I uninstall a Windows Service when there is no executable for it left on the system? I can not run `installutil -u` since there is not executable left on the system. I can still see an entry for the service in the Services console. 

The reason for this state is probably because of a problem in the msi package that does not remove the service correctly, but how do I fix it once the service is in this state?

How can I completely uninstall Anaconda from MacOS Sierra and revert back to the original Python? I have tried using `conda-clean -yes` but that doesn&#39;t work. I also remove the stuff in `~/.bash_profile` but it still uses the Anaconda python and I can still run the `conda` command.

I would like to remove and/or deactivate the `Emmet` package in Sublime Text 2.

Should I just remove the `Emmet` directory or what is the typical workflow for removal of a package?

How to remove a package in sublime text 2

My application installs other applications, and it needs to keep track of what applications it has installed. Of course, this could be achieved by simply keeping a list of installed applications. But this should not be necessary! It should be the responsibility of the PackageManager to maintain the installedBy(a, b) relationship. In fact, according to the API it is:

public abstract String &lt;b&gt;getInstallerPackageName&lt;/b&gt;(String packageName) - 
&lt;i&gt;Retrieve the package name of the application that installed a package. This identifies which market the package came from.&lt;/i&gt;

&lt;h2&gt;The current approach&lt;/h2&gt;
&lt;b&gt;Install APK using Intent&lt;/b&gt;

    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setDataAndType(apkUri, &quot;application/vnd.android.package-archive&quot;);
    startActivity(intent);

&lt;b&gt;Uninstall APK using Intent:&lt;/b&gt;

    Intent intent = new Intent(Intent.ACTION_DELETE, Uri.fromParts(&quot;package&quot;,
    getPackageManager().getPackageArchiveInfo(apkUri.getPath(), 0).packageName,null));
    startActivity(intent);

This is obviously not the way e.g. Android Market installs / uninstalls packages. They use a richer version of the PackageManager. This can bee seen by downloading the Android source code from the Android Git repository. Below are the two hidden methods that corresponds to the Intent approach. Unfortunately they are not available to external developers. But perhaps they will be in the future?

&lt;h2&gt;The better approach&lt;/h2&gt;

    public abstract void deletePackage(
            String packageName, IPackageDeleteObserver observer, int flags);


&lt;h2&gt;Differences&lt;/h2&gt;
* When using intents the local package manager is not made aware of which application the installation originated from. Specifically, getInstallerPackageName(...) returns null.
 
* The hidden method installPackage(...) takes the installer package name as a parameter, and is most likely capable of setting this value.

&lt;h2&gt;Question&lt;/h2&gt;
&lt;b&gt;Is it possible to specify package installer name using intents?&lt;/b&gt; 
&lt;i&gt;(Maybe the name of the installer package can be added as an extra to the installation intent?)&lt;/i&gt; 


&lt;i&gt;Tip: If you want to download the Android source code you can follow the steps described here: &lt;a href=&quot;http://source.android.com/source/downloading.html&quot;).&gt;Downloading the Source Tree&lt;/a&gt;.

I have an issue that I can only assume is with Xcode, where my apps take forever to run and crash the phone/restart about 75% of the time. I tried using older versions of the code that I&#39;d saved instead, but they had the same effect, which they didn&#39;t use to have about a month ago. 

I&#39;ve looked up every single possible way to solve this issue for the past few weeks have haven&#39;t found anything, so I want to completely uninstall Xcode and clear all settings; but I can&#39;t find a way to do this. I can uninstall it, but when I reinstall it, it still has all of my old settings and lists of projects etc. How can I completely uninstall it?

I need to clean install vscode on my mac. I opened the terminal and removed the `.vscode/` from `~`. I also delete the `Visual Studio Code.app/` from `/`. However, after deleting all that and download a fresh copy, I installed and open the editor and the editor remembered the last project I had. For me, that means that it is something else I need to delete but I can&#39;t find it. I went to the documentation but can&#39;t find anything about uninstalling the editor. Does anyone know how to completely uninstall VSCode from mac?

However, this doesn&#39;t seem to work in reverse.

What is the correct way to remove a package from Laravel using PHP Composer?

So far I&#39;ve tried:

1. Remove declaration from file *composer.json* (in the &quot;require&quot; section)
2. Remove any *class aliases* from file *app.php*
3. Remove any references to the package from my code :-)
4. Run `composer update`
5. Run `composer dump-autoload`

None of these options are working! What am I missing?

I&#39;ve been looking to find a CLEAN solution to completely and ultimately remove Visual Studio 2010 from my computer. When you install Visual Studio, it also installs a bunch of programs (about 55) in the add/remove programs panel (`appwiz.cpl`). 

I&#39;ve already tried a small utility made by Microsoft but it does almost nothing. 

I&#39;m really looking now for a better way to uninstall any version of Microsoft Visual Studio. 
Because I have a lot of computers, I&#39;m often switching to a version or another or I just decide that I don&#39;t need it anymore on one computer to get back some space.

Really, what&#39;s the best solution? If there isn&#39;t one, why haven&#39;t Microsoft developed one that is actually working well?

I googled and found a utility that uninstalls visual studio 2010 [here][1] but nothing exists for Visual Studio 2012, 2013 and 2015. My questions are:

Is there any generic utility that uninstalls Visual Studio by Version ? 

Or Is there a way to forcefully uninstall visual studio 2012 onward without using the Program and Features menu?

I installed all of my gems using bundler via the Gemfile. I thought (mistakenly) that if I deleted a gem from my Gemfile and ran &#39;bundle install&#39; that the deleted gems would be uninstalled. I&#39;ve looked at the bundler help file and, so far as I can tell, it does not have a way to uninstall gems. 

Do I just use gem uninstall x for everything? Is this going to confuse bundler?

All we know that usual (in practice any) antivirus application before uninstall used to fire simple dialog like: &quot;You&#39;re going to uninstall app, are you sure?&quot; - &quot;yes/no&quot;.

Yes, I know that I can intercept package delete intent using intent-filter like:

    &lt;activity
        android:name=&quot;.UninstallIntentActivity&quot;
        android:label=&quot;@string/app_name&quot; &gt;
        &lt;intent-filter&gt;
            &lt;action android:name=&quot;android.intent.action.VIEW&quot; /&gt;
            &lt;action android:name=&quot;android.intent.action.DELETE&quot; /&gt;
            &lt;category android:name=&quot;android.intent.category.DEFAULT&quot; /&gt;
            &lt;data android:scheme=&quot;package&quot;  /&gt;
        &lt;/intent-filter&gt;
    &lt;/activity&gt;

But problem is in simple fact that this intercepts **any** delete requests and moreover this will fire chooser dialog between my app and stock installer. So if user will select stock installer - I won&#39;t be able to do anything.

My goal is not to prevent user from uninstalling of my app, but just rollback changes made by my app.

Learning from those antivirus apps I see that this kind of operation is possible, so please help me and explain how it is possible?

Anyway it means that there&#39;s way to intercept uninstallation procedure in order to either prevent uninstall or do some finalizing job.

How can an app detect that it&#39;s going to be uninstalled?

I wrote an app with device admin enabled (DevicePolicyManager) and installed.
But when I want to uninstall it, it returns failed with this message

&gt; WARN/PackageManager(69): Not removing package com.mypackage.test: has active device admin

How can I uninstall it, or uninstall it programmically?
Thanks.

I want to uninstall Eclipse version Mars 2, but it doesn&#39;t appear in the &quot;Programs and Features&quot; area of the Windows Control Panel. The installer has installed start menu shortcuts and other artifacts, so it&#39;s not just a matter of deleting the installation folder.

I want to completely remove Python 2.7 from my Mac OS X 10.6.4. I managed to remove the entry from the `PATH` variable by reverting my `.bash_profile`. But I also want to remove all directories, files, symlinks, and entries that got installed by the Python 2.7 install package. I&#39;ve got the install package from http://www.python.org/. What directories/files/configuration file entries do I need to remove? Is there a list somewhere?

I am currently trying to install the XNA Game Studio for Visual Studio Express 2013. And I accidentally ran the .vsix program BEFORE actually installing the XNA framework.

After installing it and re-running the .vsix, I get a message error saying that the extension has already been installed. Which is not false.

I have tried a lot of things to &quot;delete&quot; the empty extension : going in %LocalAppData%\Microsoft\VisualStudio and trying to find the extension, but finding myself with nothing, for example.

I would like to know how I can properly uninstall and reinstall the framework.

I installed kubernetes cluster using *kubeadm* following this [guide][1]. After some period of time, I decided to reinstall K8s but run into troubles with removing all related files and not finding any docs on official site how to remove cluster installed via kubeadm.
Did somebody meet the same problems and know the proper way of removing all files and dependencies? Thank you in advance.
  
For more information, I removed *kubeadm*, *kubectl* and *kubelet* using `apt-get purge/remove` but when I started installing the cluster again I got next errors:

    [preflight] Some fatal errors occurred:
    	Port 6443 is in use
    	Port 10251 is in use
    	Port 10252 is in use
    	/etc/kubernetes/manifests is not empty
    	/var/lib/kubelet is not empty
    	Port 2379 is in use
    	/var/lib/etcd is not empty

I am trying to find some `sudo`-free solution to enable my users install and unistall my application. Using

    set(CMAKE_INSTALL_PREFIX &quot;$ENV{HOME}/opt/${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}/&quot;)
    SET(CMAKE_INSTALL_RPATH &quot;$ENV{HOME}/${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}/&quot;)

I can direct the files to the user&#39;s home directory, and

    make install

works fine. With reference to 
https://stackoverflow.com/questions/1439950/whats-the-opposite-of-make-install-ie-how-do-you-uninstall-a-library-in-lin
I did not find any idea, which is `sudo`-free and is not complex for a non-system-admin person. 

1. Is anyhow `make uninstall` supported by CMake?

2. My uninstall is quite simple: all files go in a subdirectory of the user&#39;s home. In principle, removed that new subdirectory could solve the problem. Has `make install`, with parameters above, any side effect, or I can write in my user&#39;s guide that the newly produced subdirectory can be removed as &#39;uninstall&#39;?

I&#39;ve been trying out ReSharper and decided that I&#39;d like to uninstall it.  However, after doing so, Visual Studio no longer shows red underline highlighting that it normally uses to identify the location of errors in the code.

This has happened on two of our PCs so far. I&#39;ve tried a reinstall and a repair, but no luck. Any ideas how I can restore the highlighting in Visual Studio?

I&#39;ve installed docker following installation tutorial on docker.com, using `wget https://get.docker.com/ | sh` command.
Now i need to remove it entirely. `apt-get remove docker`, `apt-get --auto-remove docker`, `apt-get remove docker.io`, `apt-get --auto-remove docker.io` or any other combination doesn&#39;t work, since I didn&#39;t install it using apt-get. Is there any way to remove docker faster than removing it by hand?

(I&#39;m working on Ubuntu 14.04 if it makes any difference).

During the past years, I have installed many Python libraries with various Python versions. To make them ready to work immediately, I installed them blindly without control. Currently they&#39;re causing problems when I tried to install [pynest][1] which invokes numpy, scipy and matplotlib. After struggling, I am going to clean and reinstall Python and the libraries.

After investigation, I found Python 2.5/2.6/2.7/3.2 on my system, and each of them has some copies or other things at: (my OS == **Mac OS X 10.7.5 Lion**)

 - `/Library/Frameworks/`
 - `/opt/local/Library/Frameworks/`
 - `/opt/local/bin/`
 - `/Applications/`
 - `/usr/local/bin/` 
 - `/usr/bin/ `
 - `/System/Library/Frameworks/`

I know I&#39;m crazy to have these. Now I have removed all these except the things in `/System/Libarary/Frameworks` (I never remove any thing from `/System/Library/`). After the clean work, `which python` now gives `/usr/bin/python` which links to `/System/Library/Frameworks`. 

Now, is it a clear environment for me to reinstall python? How to double check that there&#39;s no other versions existing? How should I reinstall them to guarantee that they and their libraries won&#39;t be everywhere and have many copies again? 

I want to install a clean Python 2.7 onto a proper location, and make my system know exactly where it is and never install any libraries somewhere else. Please give me some advice that how to manage it like in a professional way.

For your information, here is my current `$PATH`, I think it should be modified:

    /opt/local/bin:/opt/local/sbin:/opt/nest/lib/python2.7/site-packages:/usr/local/lib/python2.7/site-packages:/Library/Frameworks/Python.framework/Versions/2.7/bin:/usr/texbin:/Library/Frameworks/Python.framework/Versions/3.2/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/texbin:/Library/Frameworks/Python.framework/Versions/3.2/lib/python3.2/site-packages/django/bin:/usr/X11/bin:/opt/local/bin:/opt/local/sbin:/usr/local/lib/python2.7/site-packages:/Library/Frameworks/Python.framework/Versions/2.7/bin:/Library/Frameworks/Python.framework/Versions/3.2/bin

Please let me know If you need more information. Thank you!


----------

**UPDATE**:

I&#39;m rethinking profoudly why it becomes so crazy. I believe it&#39;s because I installed things via:

 - `easy_install` / `macports` / `homebrew` / `fink` / `pip` sometimes;
 - `.dmg` sometimes; 
 - `.pkg` sometimes;
 - compile source code sometimes;

and they made things at different locations. I wonder what&#39;s the mechanism behind these ways? How do they choose target location? How to prevent them from messing things up?

I&#39;ve installed `grunt` using `sudo npm install grunt` and now I can&#39;t remove it.

I&#39;ve tried:

    $ sudo npm uninstall grunt

But it gives me a `WARN`:

&gt;     npm WARN uninstall not installed in /home/kuba/projects/node_modules: &quot;grunt-cli&quot;

I&#39;ve also tried `rm`, `remove` and `unlink`. and `-g` options, but those give:

&gt;     npm WARN uninstall not installed in /usr/lib/node_modules: &quot;grunt&quot;

But I still can run `grunt` from command line.

**EDIT**:

    $ whereis grunt
    grunt: /usr/local/bin/grunt
    $ file /usr/local/bin/grunt
    /usr/local/bin/grunt: symbolic link to `../lib/node_modules/grunt/bin/grunt&#39;
    $ ls /usr/local/lib/node_modules
    grunt jshint

**EDITOR NOTE**:

_This question was asked over 5 years ago as **How to uninstall npm package**. It&#39;s been a very useful question favourited by many, who found a solution to their problem, so I&#39;m changing it back from a recent edit that called it **How to uninstall grunt package**, because it requires the same procedure as any other `npm` package._

My app is using Google&#39;s C2DM (push notification) to notify users about new activity from friends. Once they install the app I register the device with C2DM servers and store user&#39;s phone number. So I know that the user is using my app and I can send him/her the push notifications. But what happens if users uninstalls my app, is there a way to catch it in my app? Or the only way is to catch an error on my server when I send a C2DM and it&#39;s unreachable, then mark a user as inactive? 

I would love to notify users when their friends are using an app and when they no longer do.

What&#39;s is the best solution for this scenario?
