Stuck on Update 11.10(x64) to 12.04(x64)

[tonezone]

I tried running the update to version 12.04, but during update it got stuck saying Downloading Dropbox ... 99%. I tried ctrl + c to stop it, and restarted, but as soon as I started the update again it froze in the same place. Right now some of the system is upgraded but other parts aren't and it's very unstable.

I have another problem that might be related. Ever since I updated from 10.10 to 11.10 every time I install software, the software manager talks about problems updating samba4. When I ran sudo dkpg --configure -a it eventually froze on the dropbox download but it gave the error I've always been getting with samba. Here are the samba related parts:

This pattern of cumulative errors following a number of upgrades is typical to Buntu. It hardly ever pays to search for and correct them, so my advice is a fresh install.

[tonezone]

I can live with the problems with samba4, but because of freezing during the dropbox installation I cannot install or uninstall any software. Is there any way I can uninstall dropbox, reinstall it, or skip it? Having to do a fresh install is pretty drastic. If I could return to 11.10 that would be fine too. This seems like a pretty lame way to kill a computer, a single piece of software stopping all installation of software.
