Can not Upgrade to Ubuntu 14.04
Solution 1
Look in
/var/log
for release-upgrader log files that will have more details.The error message explains:
This can be caused by:
...
* Unofficial software packages not provided by Ubuntu
So, do you have any software from PPAs installed, or have you edited any of the default sources? If so, that's probably the problem. Disable any PPAs or other third-party repos and try again. If it still doesn't work you might need to actually uninstall some packages or replace them with versions from the official repos.
Solution 2
I've been following this thread since 14.04 came out and finally resolved my issues: it turned out that (for me) the error was caused by having Cinnamon installed.
I used Synaptic to search for and remove all of Cinnamon as well as Nemo and Muffin (two utilities that are part of Cinnamon). The regular distro upgrade command
sudo do-release-upgrade
then worked perfectly.
Solution 3
When I updated to kubuntu 15.04, I had the same problem due to php
, MSQL
, xserver-xorg-video
packages which were broken.
You can view broken libs by:
grep Broken /var/log/dist-upgrade/apt.log
To remove xserver-xorg-video use below command:
sudo apt-get remove xserver-xorg-video-*
I also removed some conflicting mysql
and php
libs using synaptic package manager.
Please do backup of databse before remove mysql,php libraries
Thanks

When I try to upgrade from Ubuntu Gnome 13.10 to Ubuntu 14.04, the upgrade application fails with the following message:
Could not calculate the upgrade. An unresolvable problem occurred while calculating the upgrade.`
Here is the complete log:
$ cat /etc/issue Ubuntu 13.10 \n \l $ sudo apt-get update $ sudo apt-get upgrade $ sudo do-release-upgrade Checking package manager Reading package lists... Done Building dependency tree Reading state information... Done Building data structures... Done Calculating the changes Calculating the changes 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. Restoring original system state Aborting Reading package lists... Done Building dependency tree Reading state information... Done Building data structures... Done
Am I missing something? or it is just a bug?
UPDATE: I analyzed the log file and found that
do-release-upgrade
is complaining about some obsolete packages.$ cat /var/log/dist-upgrade/main.log | grep Obsolete 2014-04-28 09:16:23,678 DEBUG Obsolete: flashplugin-nonfree-extrasound:i386 (..)
After removing those packages, I was able to proceed with the upgrade.

Admin about 10 yearsIf you solved the problem, please explain how.

Greg Kramida almost 10 yearsFor me, it was necessary to re-install (sudo apt-get install --reinstall ...) the few "broken" packages, which I found using DaShaun's solution from here: askubuntu.com/questions/360293/…

JJD almost 10 yearsI had to
sudo apt-get remove postgresql-9.3-postgis-2.1
which I found mentioned in/var/log/dist-upgrade/20140724-1521/main.log
:ERROR: Dist-upgrade failed: 'The package 'postgresql-9.3-postgis-2.1' is marked for removal but it is in the removal blacklist.'
