Actually you can. However it requires an in-place reinstall. Save your
Markings (Synaptic|File|Save Markings as|Save full state) just incase
you do need to reinstall any particular program. Reinstall using the
previous version using the same partition (manually) and ensure that you
do not allow ubiquity to reformat. You'll need to do all of your updates
again, but your /home & /opt folders will remain intact & working.
