I had similar problems, but with a bad /etc/rc2.d/S91Samba link to a nonexistent /samba directory. The error message implied something was wrong with one of the samba*.deb files. However, removing the symlink resolved this problem.
Then I ran into problems with firestarter (while running the recommended "sudo apt-get install -f" command. I had installed firestarter previously, but it failed to start during the install/upgrade. I tried running it separately from the command line and I got an error that it had never been configured before (?). I "solved" this problem using "dpkg" to remove firestarter. At this point, the update manager completed successfully and I rebooted successfully. However, samba and firestarter will have to be re- installed, it appears (I upgraded about an hour ago). -- Can't calculate the upgrade with unofficial mesa/compiz packages https://launchpad.net/bugs/58424 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
