Upgrading to 17.03

[leszek]

Are you sure the installation went fine ? It looks strange to me. From what version did you upgrade ?
If its a totally fresh 2.1 it might have pulled an updated maui-apt-config which disabled the backports repos again.
Have you checked if those are still ticked and everything is updated correctly ?

Can you execute

Code:

sudo apt-get install -f

to see if it is able to fix anything.
