I'm trying to install mc using apt-get:

apt-get install mc

... and get the following error:

Failed to fetch 404 Not Found [IP: 80]

Tried /etc/apt/sources.list, fetching specific version, tried -t, tried "man apt-get"... but I cannot get through this. How can I fix this?

This is because apt's package index that lists particular versions of packages is out of date on your system: just update it with sudo apt-get update.
