The [Ubuntu git maintainers team has a PPA](https://launchpad.net/~git-core/+archive/ppa) just for that

    ppa:git-core/ppa

Just do:

    sudo add-apt-repository ppa:git-core/ppa
    sudo apt-get update
    sudo apt-get install git

If `add-apt-repository` command is not found, install it first with

    sudo apt-get install software-properties-common python-software-properties

The question was: &quot;What to do when `sudo add-apt-repository ppa:git-core/ppa` command fails&quot;.

I had the same issue in a VM behind a proxy. I resolved it with the following two steps:

 1. Set up proxy environment variables

        export http_proxy=http://&lt;user&gt;:&lt;pwd&gt;@&lt;proxy_url&gt;:&lt;port_number&gt;
        export https_proxy=http://&lt;user&gt;:&lt;pwd&gt;@&lt;proxy_url&gt;:&lt;port_number&gt;

 2. Run the `add-apt-repository` command again as sudo with the `-E` option that preserves the user environment:

        sudo -E add-apt-repository ppa:git-core/ppa


**Just follow below commands to update latest version of git**

    sudo add-apt-repository ppa:git-core/ppa -y
    sudo apt-get update
    sudo apt-get install git -y
    git --version

To install or update Git in the latest version of Ubuntu, simply type following command in terminal and hit enter (return).

    sudo apt-get install git

For checking Git version.

    git --version 

or super manual method

download git source from git hub and then

    make prefix=/usr/local all
    sudo make prefix=/usr/local install

I have not used Redis yet, but I heard about it and plan to try it as cache storing.

I heard Redis using memory as cache store database, so what&#39;s the difference if I use a variable as an object or dictionary datatype to store data? like:

    var cache = {
        key: {
        
        },
        key: {
        
        }
        ...
    }

What&#39;s the advantage Redis have?

My Current git version 1.7.9.5...

I need to upgrade to at least git 1.7.10 to have `git clone` command to work properly

I tried `sudo add-apt-repository ppa:git-core/ppa` for upgrading but resulted in this : 

    Traceback (most recent call last):
      File &quot;/usr/bin/add-apt-repository&quot;, line 125, in &lt;module&gt;

Unity creates and deletes meta files for *folders* inside the Asset folder.

That can create an annoying situation when using version control (that you can skip and go to the questions): someone creates a folder of files that will be ignored but forget to ignore the folder&#39;s meta file. Unity creates the meta file and this person adds the meta to version control. Another person gets the changesets and, since they don&#39;t have the folder, _their_ Unity deletes the meta file and they remove the meta file from version control. Not everyone in the team understand this, so the process is perpetuated in a loop from hell.

Surprisingly this happens all the time. So, two questions:

1. Is it important to version folder meta files? 
2. Is there a way to automatically ignore folder meta files - particularly on git or mercurial?

Ignoring folder meta files on version control

Even after reading this question: [git-push-current-branch][1], I am still having difficulty figuring out how I should write my `git push` command. As mentioned in the question link, it&#39;s not clear from the documentation.

I would like to use my &#39;real world&#39; example. Following is what I see when I run the `git status` command on the top level of my branch:

&gt; On branch amd_qlp_tester
&gt; 
&gt; Your branch is ahead of &#39;origin/amd_qlp_tester&#39; by 5 commits.
&gt; 
&gt; etc...

My branch name is `amd_qlp_tester` but it was &quot;branched&quot; off from the main branch (if I have the terms wrong it&#39;s because of my SVN background). But then there is also the name `origin/amd_qlp_testser`

So how do I phrase my push command?

Is it any of the following?

    git push origin/amd_qlp_tester
    git push origin amd_qlp_tester
    git push amd_qlp_tester
    git push origin
    git push

I want to get the last commit ID of the **remote** git repo.

The command `git rev-parse HEAD` works for a locally-cloned git repo, but I want to get it from the original GIT repo by a CURL command or so. 

Eg: I want to get the last commit ID of the git URL https://git.appfactorypreview.wso2.com/history/apiapp.git/.

How?

I am trying to set up a new git repo to a pre-existing remote repo.

I want my local files to overwrite the remote repo, but git says that I first have to pull those remote files in and merge them.

Is there any way to pull but make sure that the local files are not overwritten by the remote?

How do I pull files from remote without overwriting local files?

I get the following error after I run the steps below:


    To git@provider.com:username/repo-name.git
     ! [rejected]        dev -&gt; dev (already exists)
    error: failed to push some refs to &#39;git@provider.com:username/repo-name.git&#39;
    hint: Updates were rejected because the tag already exists in the remote.

1. Created the repository
2. Cloned the repo on the local machine.
3. Modified the README file, commited the changes and pushed the commit.
4. Created tag `dev`: `git tag dev`
5. Pushed tags: `git push --tags`
6. Modified the README file, commited the changes and pushed the commit.
7. Deleted tag `dev` , created it again and pushed tags:

        git tag -d dev
        git tag dev
        git push --tags

Why is this happening?

I am on Mac. My friends that use Linux (Ubuntu) don&#39;t have this problem. I know that I can use `git push --tags -f` to force the tag update, but this is dangerous (e.g. rewriting a commit made by mistake only in the tag, not in the branch).

The Oracle Java package for Ubuntu interactively asks about the License Agreement. So I have to say &#39;OK&#39; and then &#39;yes&#39; every time, but I&#39;d like to automate it. What I do is this:

    sudo add-apt-repository -y ppa:webupd8team/java
    sudo apt-get update
    sudo apt-get -y install oracle-java7-installer 

Is there a simple way to automate the agreement process without using expect?

Auto yes to the License Agreement on sudo apt-get -y install oracle-java7-installer

I have an ansible task which creates a new user on ubuntu 12.04;
  

    - name: Add deployment user
        action: user name=deployer password=mypassword

it completes as expected but when I login as that user and try to sudo with the password I set it always says it&#39;s incorrect. What am I doing wrong?

I have a new Ubuntu 12.04 VPS. I am trying to write a setup script that completes an entire LAMP installation. Where I am having trouble is appending a line to the `/etc/hosts` file. My current hosts file looks like this:

    127.0.0.1       localhost Venus

    # The following lines are desirable for IPv6 capable hosts
    ::1     ip6-localhost ip6-loopback
    fe00::0 ip6-localnet
    ff00::0 ip6-mcastprefix
    ff02::1 ip6-allnodes
    ff02::2 ip6-allrouters

I would like it to look like this:

    127.0.0.1       localhost Venus
    192.241.xx.xx  venus.example.com venus

    # The following lines are desirable for IPv6 capable hosts
    ::1     ip6-localhost ip6-loopback
    fe00::0 ip6-localnet
    ff00::0 ip6-mcastprefix
    ff02::1 ip6-allnodes
    ff02::2 ip6-allrouters

I have tried a variety of `sed` commands using the append (`\a`) command. For some reason Ubuntu either just echoes the contents of the `hosts` file in terminal or does nothing at all. How would I properly inject the second line into the file with a bash script?

**I have just reinstalled Ubuntu 12.04 LTS, and before anything else i did these steps**:

1. Installed Node via package manager with the following script

        sudo apt-get update
        
        sudo apt-get install python-software-properties python g++ make
        
        sudo add-apt-repository ppa:chris-lea/node.js
        
        sudo apt-get update
        
        sudo apt-get install nodejs
        
2. Tried to install yeoman, express, n, yeoman&#39;s generators globally and all of them returned the same error

    &gt; npm ERR! Error: EACCES, symlink &#39;../lib/node_modules/n/bin/n&#39;

3. **Reclaimed ownership of the following folders recursively** ~/.npm, /usr/lib/node, /usr/lib/node_modules, and of the following symlinks /usr/bin/node, /usr/bin/nodejs **with absolutely no success**

I need to install yeoman and its generators without sudo not to be in trouble later on :(

NPM modules won&#39;t install globally without sudo

Hi I&#39;m a bit of a shell n00b.

Can anyone tell me how I would check the version of MongoDB that is installed on my Linux Ubuntu machine?

I see that my MongoDB shell version: 1.2.2 so Im pretty sure that MongoDB itself is out dated too. And does anyone know of any &#39;How to update MongoDB&#39; docs? I find mongodb.org to be a bit confusing.

Please and thank you.

----------------------------

Ok if I use db.version() inside of mongo shell it says 1.2.2

If I $ mongod --version I get this:

    db version v1.2.2, pdfile version 4.5
    Wed Oct 16 10:28:22 git version: nogitversion

I ran 

    sudo apt-get update
    sudo apt-get install mongodb

and get 

    sudo apt-get install mongodb
    Reading package lists... Done
    Building dependency tree       
    Reading state information... Done
    mongodb is already the newest version.
    0 upgraded, 0 newly installed, 0 to remove and 179 not upgraded.
    
    mongod --version
    db version v1.2.2, pdfile version 4.5
    Wed Oct 16 10:31:07 git version: nogitversion

So why isn&#39;t it updating? Is apt-get pointing at the wrong repo / source?
