I know upgrades are supposed to work, but they almost never go 100% percent right.
Use dpkg/synaptic to backup your installed packages and backup your /home...then commit to the time to going fresh install. If you use LTS releases, you'll only be doing it at most every other year.

IMHO, it is worth the time.
