Update Manager demands partial upgrade

[Marja Erwin]

I have not been able to use the update manager for the last few months. I am currently using Ubuntu 11.04, and am avoiding upgrading to 11.10 because I have arm issues making Unity inaccessible, and I had a botched installation of Xubuntu 11.10 last year and had to reinstall Ubuntu 11.04.

The update manager reports that because "Not all updates can be installed" I need to "Run a partial upgrade to install as many updates as possible." I am concerned that a partial upgrade, upgrading part of the system to 11.10 would be even more error-prone and unstable than that botched installation. It might disable Gnome 2/Classic, and it might reverse the fixes I've used to restore working scrollbars. I would rather simply update what can be updated without this partial upgrade.
