I can also confirm that the procedure described here has reliably solved the problem for me.
Here is what I did in detail: 1. follow the official upgrade instructions (I used the console: 'sudo do-release-upgrade -m desktop'). 2. as soon as the upgrade has been completed, do NOT restart the computer yet, but open a terminal. 3. now execute the following command: 'apt-get -y install systemd-cryptsetup'. 4. now restart the computer -> works: everything is mounted as it should be.
