Today after trying to install and remove BURG and few themes I faced an issue. Now I can't install or remove anything.

Here is the output (unfortunately partly in Finnish, I couldn't change language since it also seems to depend on package listings:

lassi@lassi-ubuntu:~$ sudo apt-get autoremove

Käsittelyssä tapahtui liian monta virhettä:
 burg-theme-fortune
 burg-theme-gnome
 burg-theme-picchio
E: Sub-process /usr/bin/dpkg returned an error code (1)

Basically what seems to happen is this:

It creates the package lists, then tries to remove packet burg-theme-fortune. This fails as update-burg command was not found. Then dpkg reports an error while processing the packet.

Same goes with all 3 packages.

In the end it claims that there were too many errors, and packages stay installed.

I also tried installing burg as it tries to run command update-burg, but appears that it tries to delete these packages always when I try to install or remove or do anything with apt.

Any ideas how I could solve this issue?

Edit: Here is the output of apt-get install burg (tried installing again to get English output)
