Thank you for trying; it's rather puzzling this one. I ran the snap command on the upgraded machine and got:
robert@samhain:~$ sudo snap install hello-world [sudo] password for robert: hello-world 6.4 from Canonical✓ installed robert@samhain:~$ hello-world ERROR: ld.so: object 'libgtk3-nocsd.so.0' from LD_PRELOAD cannot be preloaded (failed to map segment from shared object): ignored. Hello World! robert@samhain:~$ So not entirely smooth, but it looks like the snap store was accessible. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/1948939 Title: chromium browser deb to snap switch kills dist-upgrade Status in chromium-browser package in Ubuntu: Incomplete Bug description: During the 16LTS to 18LTS (GUI) distribution upgrade I received a warning that the process couldn't connect to the snap store. I didn't have any snaps installed, so I continued with the distribution upgrade and everything worked OK. During the 18LTS to 20LTS (GUI) distribution upgrade I received and accepted the same warning. As before I had no snaps installed. However, I did have Chromium browser installed, and as part of the distribution upgrade this tries to switch from being installed from deb to being installed from snap. At this point the distribution upgrade came to a complete halt. Also the desktop GUI became unresponsive, but it was possible to switch to a TTY console with (say) CTRL-ALT-F4, login, and execute commands. The first time this happened I managed to recover the situation somehow, and proceeded to a working 20LTS installation (albeit with a few quirks). The second time it happened I was not, and ended up with a mish-mash of 18LTS and 20LTS that wouldn't boot to the desktop. Fortunately the second time I had made a disk image of the 18LTS system, and was able to go back to that. I removed Chromium, and trying the distribution upgrade again I was not issued with the snap store warning, and the process completed uneventfully. BTW, I tried to report this problem using ubuntu-bug, but I hit this brick wall: https://bugs.launchpad.net/apport/+bug/1160316. Hence the manual report.
