I had the same issue. Installed the beta release of gutsy from live cd. Went for updates (partial upgrade) as it was suggested. After downloading the error showed up.
-- package update-manager failed to install/upgrade: ErrorMessage: SystemError in cache.commit(): E:I wasn't able to locate file for the libc6 package. This might mean you need to manually fix this package. https://bugs.launchpad.net/bugs/121669 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
