Comment 15 for bug 1292118

wow, thanks to all, I am really surprised about so much solutions. Anyway, have choosen this and now it works again:

You need to physically download and install the latest version (after doing a basic removal of the old version - don't do a complete removal). Trying to keep the software updated by PPA won't work until the error on their end is fixed (as I remember, a missing source.list in the setup file).

Thanks Clive
