This fixed the bug for me on 20.10 after I updated relevant zfs packages to 0.8.4-1ubuntu11.1 from groovy-proposed.
After the update I installed a random package. Tried to revert to the snapshot created by apt. The package was not on my system. It worked. Then I reverted back the revert. The package was back on my system. Everything seems to work now. Thank you to everyone involved for the fix! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1894329 Title: ZFS revert from grub menu not working.
