If you list your packages for example with “dpkg -l” and notice following:
rc linux-image-3.14-7.dmz.2-liquorix-686 3.14-11 rc linux-image-3.14-8.dmz.1-liquorix-686 3.14-12 rc linux-image-3.14-9.dmz.1-liquorix-686 3.14-13 rc linux-image-3.15-2.dmz.1-liquorix-686 3.15-1
That means you have uninstalled packages but you have some leftover configuration data on your file system.
You can run the following command to purge old configuration files as root:
dpkg -l | grep ^rc | cut -d' ' -f3|xargs dpkg -P
Don’t get scared when it starts to delete files, there should not be any consequences to your running system and config files.
