This will prevent from installing or upgrading any application in Linux Mint. Fortunately, the fix is simple for this.
From the Terminal type the following commands :
- Code: Select all
sudo rm /var/lib/apt/lists/* -vf
Then input,
- Code: Select all
sudo apt-get update
This will delete the older entries and download the latest ones after which the error should no longer be there.
Hope that helps someone
