This question already has an answer here:
I can't install Midnight Commander (
mc) on Ubuntu 18.04.1.
deb http://archive.ubuntu.com/ubuntu bionic main deb http://archive.ubuntu.com/ubuntu bionic-security main deb http://archive.ubuntu.com/ubuntu bionic-updates main
And this is the reply I get when I try to install:
$ sudo apt-get install mc Reading package lists... Done Building dependency tree Reading state information... Done Package mc is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source
This didn't help (#1):
$ sudo apt-get update
This didn't help (#2):
$ sudo add-apt-repository ppa:eugenesan/ppa sudo apt-get update sudo apt-get install mc
It also didn't help to change mirror to
http://de.archive.ubuntu.com, for example.
