How to install software on an old now unsupported Ubuntu version?
I tried this:
apt-get install ubuntu-desktop
But i got this error:
Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/g/gnome-icon-theme/gnome-icon-theme_2.31.0-0ubuntu1_all.deb Connection failed
Then i tried to install gnome-icon-theme by myself, but I can't find 10.10's gnome-icon-theme in http://pkgs.org/download/gnome-icon-theme. :-(
