Gents:
Running Xeon.1240/MSI-gd55 under Ubuntu_12.04.xLTS and MATE_1.6.
Ubuntu **update manager** informs me a raft of update files await. These included Ubuntu-provided MATE_1.6 updates, but then it refuses to allow many (most??) of the updates to be installed claiming in an error-box ('...unauthenticated updates cannot be installed...') or suchlike.
There's lots of obscure error-text from download manager telling what I may/may-not do ... and by the end of it I'm not at all sure what got newly installed and what did not. Perhaps Ubuntu is complaining I did not previously use **their** version of MATE ( didn't exist) ... which in-fact I indeed did not!!!
How do I stop this obscure Ubuntu update foolishness and download (I guess) everything ! ?
