When I manually add file "/var/log/dist-upgrade/apt.log" and run again, it says with dialog:
Could not calculate the upgrade An unresolvable problem occurred while calculating the upgrade: E:Unable to correct problems, you have held broken packages. This can be caused by: * Upgrading to a pre-release version of Ubuntu * Running the current pre-release version of Ubuntu * Unofficial software packages not provided by Ubuntu This is most likely a transient problem, please try again later. -- update-manager crashes with OSError: [Errno 2]: File not found '/var/log/dist-upgrade/apt.log' https://bugs.launchpad.net/bugs/375653 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
