gzip: stdin: not in gzip format tar: Child returned status 1 tar: Error is not recoverable: exiting now
LinuxBashGzipTarLinux Problem Overview
I have a Bash script that creates a .tar.gz file, encrypts, and then sends it to a drive. However, I cannot open the .tar.gz file afterwards. Here is my process...
Bash script that encrypts.
#!/bin/sh
# Tar the automysqlbackup directory
tar -zcf "red-backup-$(date '+%Y-%m-%d').tar.gz" /var/lib/automysqlbackup/
# Encrypt the tar file
openssl aes-256-cbc -a -salt -in "red-backup-$(date '+%Y-%m-%d').tar.gz" -out "red-backup-$(date '+%Y-%m-%d').tar.gz.enc" -pass 'pass:MySecretPWD'
# Remove the original tar file
rm -rf "red-backup-$(date '+%Y-%m-%d').tar.gz"
# Upload to Google Drive
gdrive upload --file "red-backup-$(date '+%Y-%m-%d').tar.gz.enc" -p "jofhriout849uioejfoiu09"
Then I download the file and use
sudo openssl aes-256-cbc -e -in red-backup-2016-09-22.tar.gz.enc -out red-backup-2016-09-22.tar.gz
I then enter the passphrase for my file twice and I now get a file called
red-backup-2016-09-22.tar.gz
When I then try
sudo tar -zxvf red-backup-2016-09-22.tar.gz
I get
gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now
I have also tried renaming the file .tar and also tried
sudo tar xvf red-backup-2016-09-22.tar.gz
and
sudo tar xvf red-backup-2016-09-22.tar
tar: This does not look like a tar archive
tar: Skipping to next header
tar: Exiting with failure status due to previous errors
Where am I going wrong?

This means the file isn't really a gzipped tar file -- or any kind of gzipped file -- in spite of being named like one.
When you download a file with wget
, check for indications like Length: unspecified [text/html]
which shows it is plain text (text) and that it is intended to be interpreted as html. Check the wget
output below -
wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u144-b01/090f390dda5b47b9b721c7dfaa008135/jdk-8u144-linux-x64.tar.gz"

This sort of confirms that you haven't received a gzip file.
For a correct file, the wget
output will show something like Length: 185515842 (177M) [application/x-gzip]
as shown in the below output -
wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u144-b01/090f390dda5b47b9b721c7dfaa008135/jdk-8u144-linux-x64.tar.gz"

The above shows a correct gzip
application file has been downloaded.
You can also file
, head
, less
, view
utilities to check the file. For example, an HTML file would give the below output -
head jdk-8u144-linux-x64.tar.gz
Output:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link href="/css/print.css" rel="stylesheet" media="print">
<link href="/css/main.css" rel="stylesheet" media="screen">
<link href="/css/font-awesome.min.css" rel="stylesheet">
The above shows it is indeed an HTML page which we are trying to unzip/untar - something that won't work. If it was indeed a correct zip file (binary in nature) the output of head
would have produced garbage - something like below -
head jdk-8u144-linux-x64.tar.gz
Output:

Try downloading from the official site and check if their download links have changed. Also check your proxy settings and make sure you have the right proxies enabled to download/wget
it from the correct source.
Solution 2 - Linux
First check the type of compression using the file
command:
file name_name.tgz
Output: If the output is " XZ compressed data", then use tar xf <archive name>
to unzip the file, e.g.
-
tar xf archive.tar.xz
-
tar xf archive.tar.gz
-
tar xf archive.tar
-
tar xf archive.tgz
Solution 3 - Linux
Just click first on that link and go to the HTML page where actual downloads or mirrors are.
It's really misleading to have a full link which ends in .tgz when it actually leads to an HTML page where the real download links are.
I had this problem downloading Apache Spark and Wget-ing it into Ubuntu.
https://spark.apache.org/downloads.html
Solution 4 - Linux
Initially, check the type of compression with the below command:
`file <file_name>`
If the output is a POSIX compressed file, use the below command to uncompress:
`tar xvf <file_name>`
Solution 5 - Linux
Sometimes the .gz
extension is wrongfully appended to the filename.
- Run
file foo.csv.gz
to know the actual file type. - Rename the file to
foo.csv
or whatever the actual file type is.
Solution 6 - Linux
Add "-O file.tgz" or "-O file.tar.gz" at the end of the wget command and extract "file.tgz" or "file.tar.gz".
Here is the sample code for Google Colaboratory:
!wget -q --trust-server-names https://downloads.apache.org/spark/spark-3.0.0/spark-3.0.0-bin-hadoop2.7.tgz -O file.tgz
print("Download completed successfully !!!")
!tar zxvf file.tgz
Note: Please ensure that the http path for tgz is valid and the file is not corrupted.
Solution 7 - Linux
cd /Whatever/Directory/Path/The/File/Is/In
chmod +x xampp-linux-x64-7.0.6-0-installer.run
sudo ./xampp-linux-x64-7.0.6-0-installer.run
It works.
For more information, refer to Installing XAMPP on Linux Mint.
Solution 8 - Linux
unxz worked for me:
sudo unxz fileName.xz
Solution 9 - Linux
This is probably because of your gzip version incompatibility.
Check these points first:
> which gzip
/usr/bin/gzip or /bin/gzip
It should be either /bin/gzip or /usr/bin/gzip. If your gzip points to some other gzip application, please try by removing that path from your PATH environment variable.
Next is
> gzip -V
gzip 1.3.5 (2002-09-30)
Your problem can be resolved with these check points.
