I downloaded GoblinHack from sourceforge earlier today. (Today is my first full day with Linux actually installed on a computer) I'm trying to install this game but mintInstall doesn't have it and I'm not sure how to get the package into Synaptic Package Manager. I've tried "sudo apt install goblinhack" but I get an error message like this: "E: Could not get lock /var/lib/dpkg/lock - open (11 Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?"
So I'll probably feel dumb in a minute, but thanks for your help!
Also, I've tried using RUNME. It doesn't work. Pretty much nothing happens.
