I had Ubuntu 14.04 and Windows 10 on my laptop. I upgraded the Ubuntu to 16.04, but it is not working fine. Instead of fixing everything in this installation, is there a way to reset everything in Ubuntu to have like a fresh installation of 16.04, and keep my home folder and also the Windows on the laptop? If not, can I reset as many packages as possible to 16.04 default ones?
The home partition is different from the Ubuntu system partition.
