package epoptes 0.5.2-1 failed to install/upgrade: ErrorMessage: subprocess installed post-installation script returned error exit status 1

[Angutivik Casper Rúnur Tausen Hansen]

I can't install or delete any files from the computer. I wanted to install GIMP 2.8 (unstable) and now it just wont install anything.
After I'd deleted the ppa stuff for GIMP, I wanted to re-install GIMP 2.6 and now it just won't install. I've only tried through the software center.

Angutivik, you reported this bug 3 times, and I've been marking it as a duplicate of LP bug #975433.

In other words, this bug has been solved, and to get around it, you need to run:
sudo service epoptes stop
sudo apt-get update
sudo apt-get dist-upgrade
