I can't install Midnight Commander (mc) on Ubuntu 18.04.1.
/etc/apt/sources.list file:
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

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.
