Upgrading oldish releases are a pain. I tried “official” ways to upgrade my Saucy Salamander Eeepc. No way.
I got to do it the hard way, treating that Ubuntu like the Debian it is underneath. A power blow of apt-fu:
%s/saucy/wily/gc
:wq
apt-get update && apt-get dist-upgrade
Now, that’s taking an hellish of time on such an aging net-top and such a worm-hole jump, jumping at least 4 releases requires to dive into a console, yes, those DOS like interface that still lives underneath your shiny desktop and hammering some
while (dpkg –reconfigure -a; apt-get -f install)
