Upgrading my desktop from an up-to-date Ubuntu 11.10 to 12.04 LTS proved to be a nightmare, although it worked out in the end. On the other hand, upgrading my laptop from Ubuntu 10.04 LTS to 12.04 LTS proceeded without incident or error. I had one last upgrade to try.
I had been running Kubuntu 11.10 in a VMWare virtual machine for some time. I decided the other day to upgrade it to Kubuntu 12.04 LTS. I started by ensuring that all 11.10 packages were up to date, then executed the version upgrade using the GUI updater. I really don’t have anything to say other than it proceeded smoothly and produced a perfectly operating Kubuntu 12.04 LTS system that retained my previous configuration.
Of course, the virtual machine doesn’t see the underlying nVidia 8800 GTS card, so the nVidia 295.40 driver bugs didn’t affect the VM. Also, KDE doesn’t use compiz or Unity, so whatever conflict exists between those two didn’t affect the Kubuntu upgrade.
Oh, and the cube works perfectly:
So, upgrades to 12.04 LTS Precise Pangolin run 2 out of 3 as trouble-free. The nVidia drivers appear to be the primary cause of heartache in the first upgrade, but the lingering conflict between compiz and Unity remains.
