Ubuntu 15.04 - apt-get update fills up disk space during download

If during execution of apt-get update after Ubuntu 15.04 64 bit installation, you get a file download that just grows infinitely until it fills up your disk like this...

root@ts036953:/home/pssuser# apt-get update

Get:26 vivid/restricted Translation-en [4,228 B]
Get:27 vivid/universe Translation-en [4,456 kB]
Get:28 vivid-updates/main Sources [598 B]
100% [28 Sources 2,644 MB/2,644 MB 100%] [7 Packages 2,911 MB/2,911 MB 100%]^C

Break the command and then Execute the following command to see the offending file that keeps growing when downloaded during apt-get update, then delete the file or all the file in the /var/lib/apt/lists directory.

root@ts036953:/home/pssuser# ls -latr /var/lib/apt/lists/

To delete of the files in the location where the offending file is execute the following command. Obviously your path might be different to mine so make sure you use the right path for the location of the offending infinitely growing file.

root@ts036953:/home/pssuser# rm /var/lib/apt/lists/partial/*

apt-get update should now run fine.

 root@ts036953:/home/pssuser# apt-get update

Failed to restart mysql.service: Unit mysql.service is masked

On starting the upgrade of Openstack to Kilo, I had a problem starting the mysql/MariaDB as I kept getting an error as follows:

root@ts036953:/home/pssuser# service mysql restart
Failed to restart mysql.service: Unit mysql.service is masked.


root@ts036953:/home/pssuser# rm -r /var/lib/mysql*        # Remove any old database setup
root@ts036953:/home/pssuser# mysql_install_db -u mysql    # Install new database
root@ts036953:/home/pssuser# systemctl unmask mysql.service    # Emables the service for systemd
root@ts036953:/home/pssuser# service mysql start        # start the service.

dpkg-statoverride: error: an override for

You are trying to install a debian package (e.g. linux-image-3.16.0-31-generic_3.16.0-31.43~14.04.1_amd64.deb) with the following command:

root@ts037152:/home/pssuser# dpkg -i linux-image-3.16.0-31-generic_3.16.0-31.43~14.04.1_amd64.deb

To resolve the statoverride error, run the following command:

root@ts037152:/home/pssuser# dpkg-statoverride --remove /boot/vmlinuz-3.16.0-31-generic

Then rerun your installation command for the package.

Hope that helps.

Yours truly,
