Just upgraded to Raring from Quantal!

LAMP stack totally screwed. Password seem to be corrupted now cant access phpmyadmin! I made sure to NOT set that to upgrade.
Has rolled back to stock graphics driver, thanks!
LO crashes on start.
Desktop sharing just aint working.
I had 3 accounts on the machine which upgraded, all password protected. One now doesn't have a password, one now doesn't recognise the correct password
The list goes on & on...

We are now EIGHT years down the line from when Ubuntu first hit the disk of many of us hardened geeks & quite frankly it's not good enough!
