Ubuntu 18.04 failed upgrade from 16.04 LTS

  • 772

I am using Ubuntu 16.04 LTS and I ran do-release-upgrade -d but the upgrade failed with an error message saying packages have unmet dependencies.

sudo apt-get -f install and sudo apt update && sudo apt upgrade also failed to fix the errors.

Here is the full error message:

Correcting dependencies... failed.

E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

E: Unable to correct dependencies

In addition, the GUI got somewhat strange.

What has happened?

  1. This worked for me:

    Open a terminal with: CTRLALTF1 (enter your user and password) then 

    sudo apt install aptitude

    next step

    sudo aptitude install ubuntu-desktop gdm3

    you will be offered options how to fix the incompatibilities, hit a few times N and ENTER until you are suggested with some removal of old packages and installing of updated one.

    then give Y and ENTER to a solution that removes old incompatible packages and installs the new ones.

    last 

    sudo reboot

    The above worked for me.

  2. Open a terminal using Ctrl+Alt+T and type:

    update-manager -cd

    From here, try to update. If there is an error with an option that says partial upgrade, click it. This will restore the GUI. Reboot, and run the command again. There should be no error, and you can proceed with the upgrade via the GUI.

  3. You seem to have got a number of broken packages, as per the error message E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.. To resolve, look at the file /var/log/dist-upgrade/apt.log. Locate the packages that are broken and remove them with sudo apt-get remove broken-package. If there are dependency errors, then try to reinstall the package: sudo apt-get install --reinstall broken-package.

    Now try fixing dependency errors:

    sudo apt-get -f install

    Reboot and try upgrading again.
