Symptom

The /var/cache directory is extremely big and takes all the space on the root filesystem

Cause

This might happen on a system when you never clean up your apt cache

Solution

The solution is easy. You just need to cleanup your apt cache. This can be done with the following command:

apt-get clean

You can control the result with:

du -sh /var/cache

or

df -h

The cache can grow to several gigabytes and occupy all space. When you do have failures that you cannot create any files, temporary files or even cannot logon as user anymore, you should check this.

The root user always has a bit of space on the root filesystem extra. Just logon and cleanup a bit.
