Linux Mint's (I'm using Linux Mint Mate edition, 17.2 32 bit) update manager gives me:
I tried this from the terminal:
sudo rm -r /var/lib/apt/lists sudo mkdir -p /var/lib/apt/lists/partial sudo aptitude update sudo apt-get update && sudo apt-get upgrade
While that does make the problem go away, the issue is not solved because the same thing happens again.
So, how can I fix this problem?
