I can confirm that removing/renaming the multiarch file will cause lots of breakage. I got lots of problems with various libraries, mostly kerberos-related stuff. Deleting these packages would have deinstalled half of Ubuntu, so I force-deleted them (leaving their dependencies installed), then reinstalled them. At that point, I'd get the conflict with the i386 versions of the packages that was mentioned above, and would be unable to configure them (rendering them essentially nonfunctional I guess).
Restoring the multiarch file would then delete a huge list of :i386 packages, configure the packages, and restore everything to working order - including the proprietary Flash plugin that had been broken since the multiarch experiment. So I guess I'll live with the "Forget New Packages" problem and hope it's really just cosmetic - removing multiarch was definitely one of the worst experiments I ever tried on my system. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/845136 Title: Forget new packages doesn't save its action To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/aptitude/+bug/845136/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
