gzip: stdin: not in gzip format tar: Child returned status 1 tar: Error is not recoverable: exiting now
I have a bash script that creates a tar.gz and encrypts then sends to drive. However I cannot open the .tar.gz afterwards. Here is my process...
Bash Script that encrypts.
#!/bin/sh
# tar the automysqlbackup directory
tar -zcf "red-backup-$(date '+%Y-%m-%d').tar.gz" /var/lib/automysqlbackup/
# encrypt the tar
openssl aes-256-cbc -a -salt -in "red-backup-$(date '+%Y-%m-%d').tar.gz" -out "red-backup-$(date '+%Y-%m-%d').tar.gz.enc" -pass 'pass:MySecretPWD'
# remove the original tar
rm -rf "red-backup-$(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
and 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 trying
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
Any ideas where I am going wrong?
Answer
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 -
[root@XXXXX opt]# 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 -
[root@txcdtl01ss270n opt]# 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 a HTML file would give below output -
[root@XXXXXX opt]# head jdk-8u144-linux-x64.tar.gz
<!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 -
[root@XXXX opt]# head jdk-8u144-linux-x64.tar.gz

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.
Hope this helps.
