TIPS: Add PPA Work-around For Linux Mint 12 RC

There is a bug in Linux Mint 12 RC related to adding PPAs: when you add a PPA using "add-apt-repository", the .list file (under /etc/apt/sources.list.d/) uses "lisa" as the code name instead of "oneiric". Since the PPAs are not using the Ubuntu code name, they won't work and when running "sudo apt-get update", you'll get a "Failed to fetch [...] 404 Not Found" error.

A work-around is to edit the .list files under /etc/apt/sources.list.d/ and replace "lisa" with "oneiric", but to make it easier, I've updated Y PPA Manager with a work-around for this bug, so adding a PPA through Y PPA Manager should work as usual, without having to tweak anything else.

To install the latest Y PPA Manager in Linux Mint 12 RC, open terminal use the commands:

Linux Mint 12 “Lisa” RC Released!

Linux Mint 12 (right now a release candidate) definitely stands out in the crowd of Gnome 3.x Shell Linux distributions. It seems the Linux Mint team cares deeply about giving the community what it wants but doesn’t have. Linux Mint 12 is a Gnome 3.x Shell distribution that stands out on its own because rather than accept the default Gnome 3.x Shell interface like most Gnome 3.x Shell Linux distributions have done Linux Mint 12 tries its best to emulate the Gnome 2.x interface through the use of Gnome Shell extensions.
