Comment 11 for bug 300247

i was having the same problem, and like Yogi i found the files in /var/cache/apt/archives/partial/

after other reading on the web i browsed to the folder with konqueror (i am running kde). I then left clicked on each of the files and there was a package installer option that i used to install them. some of them had errors in the popup window that ran.

after doing that for all 4 files, i went back into the package manager and told it to do the upgrade again. this time it went all the way and i just rebooted with Gutsy a couple of minutes ago
