Can you show `snap changes`?

I got this problem upgrading a newly installed 18.04 to 20.04. I only run "apt dist-upgrade" before running the do-release-uprade command. Both commands was run inside a tmux shell.

The source for the fresh 18.04 install was the latest template from OnApp.

Can you show "snap change 2" or in general "snap change ID" where ID is the number listed next to the failing install?
