When I try to install a program in terminal it runs for a while and then a box come up that says "Configuring ttf-mscorefonts-installer" and asks me to hit 'OK'. But I cannot hit 'OK' or make the box go away at all. If I try to close terminal it says there are still processes running. If I close it anyway I can no longer use terminal. I read on a forum that I should just delete ttf-mscorefonts-installer, but it won't let me have permission. This is just a desktop PC in my home. So, how can I fix this problem? And how can I give myself permission to delete files?
Looks like you have hit an old bug. I thought it was already fixed. Are you trying to install wine?
The solution to this i, instead of trying to click OK with mouse, just press
If this does not work from terminal try to do the same from synaptic.
