Issues with corrupted package

[robobot]

I'm having some issues with a pad package. The package is not fully installed, and I can neither install nor remove it.

Here is the output from apt-get:

Maybe you need to run


sudo dpkg --configure -a
sudo apt-get update

[utsuprainfra]

i would try:

sudo apt-get remove packagename --force

or

sudo apt-get purge packagename

Already tried all those, and my dependency tree is okay too.
Another thing to note is that nothing depends upon this package.
Here's the output when I try to remove/purge:
