I'm very new to mint/linux/GRASS and have no clue how to deal with these errors. Can I just change the URL somewhere?
Here is the simplest reproducible command to produce a failure: sudo apt-get install mysql-client-core-5.5
Here is the output from my attempt to run/install grass:
mint@mint ~ $ grass
The program 'grass' is currently not installed. You can install it by typing:
sudo apt-get install grass-core
mint@mint ~ $ sudo apt-get install grass-core
