Something has gone wrong with the GNU Debugger. It will not update or let me remove it!
The screenshot shows it’s there but I can’t ‘tick it’
This one is on PC, 12.04
Personally I’d disable that PPA … but then again I’d not have added it in the first place … it may even be a better idea to purge the PPA, but that’s your call.
–
How do I do that, I’m not 100% sure how to do it…
Do what … I mentioned 2 courses of action ?
Sorry, purge it.
sudo apt-get install ppa-purge
then
sudo ppa-purge ppa:dns/gnu
BE AWARE - the above will remove ALL software added from that PPA (any software that was updated from the default versions will be downgraded to the version in the default repos), then disable the PPA.

Hmm … OK, that PPA doesn’t appear to be active ???
Try running:
sudo apt-get clean
then
sudo apt-get update
Then start Update Manager … and if that update is still listed, click the “Check” button … did it disappear from the list ?
That worked 
It’s gone
