Did you run do-release-upgrade (maybe by a GUI) and before doing this
disable third party repositories and did you also removed all installed
packages from third parties and local builds?

Since you can't boot, you might need to run your install in a chroot
environment, or much better, we boot it in a systemd-nspawn container,
but perhaps this isn't required.

It's nearly impossible that the UUIDs changed. Anyway, check it.

Use a live media, mount your install and run

  cat /mount/point/etc/fstab

copy and paste the output and please format it in human readable style.
Perhaps the mailing list allows to attach fstab to an email, or
consider to use e.g. http://pastebin.com/ and post the link.

Also run the command

  blkid

and post the output, also human readable formatted. Perhaps redirect
the output to a file

  blkid > blkid.txt

and attach the file to an email, assumed the mailing list should allow
it, or consider to use http://pastebin.com/ or something similar and
post the link.
