Unofficial GNOME3 on Ubuntu PPA
A friend of mine was having problems with the GNOME3 packages in Ubuntu, and after some questioning, he told me he was using a PPA from this Launchpad team:
https://launchpad.net/ubuntugnome
The GNOME3 PPA for that team seems to be just a copy of the official GNOME3 PPA, but just in case, this is a public announcement to let people know that they shouldn’t use that PPA (unless they really want to, of course), but use the official one instead, which is at:
https://launchpad.net/~gnome3-team/+archive/gnome3
That is, the official team is the gnome3-team, so please make sure to check your sources.list if you really want to use the official one.
