Upgrade from 12.04 to 14.04 failed

[xxlray]

I want to upgrade from Ubuntu 12.04 to 14.04

I start the update manager from my terminal using
sudo update-manager -d

The update procedure start but on "Setting new software channels" I get the following error message


Could not calculate the upgrade

An unresolvable problem occurred while calculating the upgrade.

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

If none of this applies, then please report this bug using the command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal.

This is my sources.list:

Try disabling these repositories and retry the upgrade.


Good Luck

In addition to what plucky said you also have maverick repositories that should be disabled.

Do an update then an upgrade before doing a release upgrade.

Thanks for the suggestions - unfortunately they did not work. I ended up in creating a new sources.list for Ubuntu 14.04 using the Ubuntu Sources List Generator (http://repogen.simplylinux.ch/). Afterwards I did "sudo apt-get update && sudo apt-get dist-upgrade". I had some dependency issues but the repeated use of "sudo apt-get -f install && sudo apt-get dist-upgrade" fixed it for me.
The only issues I found so far are that I had to remove and re-install pulseaudio and the volume indicator. Otherwise I had a humming sound coming from my speakers.


sudo apt-get -f install --reinstall pulseaudio
sudo apt-get -f install --reinstall indicator-sound indicator-sound-gtk2
