An unresolvable problem occurred while calculating the upgrade.

Please report this bug against the update-manager package and include the following error message: 'E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.'

sudo apt-get upgrade brings me this.

Dont know much on this end of Linux, still a noob.

Answer 1

For the first part about the upgrade, just copy the packages that have been kept back, each line at a time, and append them to a sudo apt-get install statement and press enter.

In your case it will become:

sudo apt-get install libgl1-mesa-dev linux-headers-generic-lts-raring linux-image-generic-lts-raring mesa-common-dev

This will take care of your 'these packages have been kept back error'.
