On upgrade from 10.04 to 10.10 BETA I experienced the same, (I should have researched before jumping in to BETA)..
sudo dpkg-divert --remove /usr/lib32/libGL.so.1.2 Notice the /lib32 not /lib as I am running on a 64bit platform. This seems to allow a purge to work but leaves some stale directories. -- package fglrx 2:8.723.1-0ubuntu2 failed to REMOVE: error exit status 2 - dpkg-divert: mismatch on package - while removing the package https://bugs.launchpad.net/bugs/566437 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
