Hello i was trying to update my ubuntu version then i get this problem.

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

Can somebody help me?

Thank You.

As i am also one of the unfortunates to have constant upgrade problems in the previous years, i really warmly recommend doing a clean install from a USB stick or a CD. Backup your files, and do a clean install.

Cheers.
