I'm running Natty and have a problem with upower. Currently installed is upower 0.9.5-4 (Maverick?), with upower 0.9.9-4 available. Update Manager won't upgrade it, but if I go to Synaptic and use Ctrl+E (force version) it prompts to remove all of the following packages: gdm gdm-guest-session gnome-power-manager gnome-session gnome-session-bin indicator-session nautilus-share ubuntu-desktop This seems like a fair chunk of the GUI, so I'm not keen to let it go ahead. Is there a better/safer way to force the package upgrade? NOTE: This machine was upgraded from Maverick to Natty using the Alternate CD a while ago. It locked-up about 80-90% through the upgrade requiring the machine to be hard reset, but it finished the upgrade process after rebooting. I was making sure everything was OK before going to Oneiric when I discovered this little gem.
