Public bug reported: Hi,
Is there a way to list the previous revisions of a snap in a specific channel and then allow the snap client to revert or install specific revisions? I understand `snap revert` exists, but it only allows to revert to the last installed and that's it. My use case is this, on an application unit using the ruby snap, it was automatically updated around 7 days ago. It wasn't until recently when we wanted to update the application where the latest ruby snap broke gem collection, see upstream bug[1]. But it wasn't known at the time so we thought to try the latest ruby from the latest channel (from 2.7/stable). So: | snap refresh ruby --channel latest/stable So now we want to revert: | $ sudo snap revert ruby | ruby reverted to 2.7.4 | $ sudo snap revert ruby | error: cannot revert "ruby": no revision to revert to What we actually want is to revert from 2.7.4 (231) in 2.7/stable to 2.7.4 (219) also in 2.7/stable. The only way seems to be to find the correct URLs for both assertion file and snap itself, download both, and to use `snap ack <assertion file>` plus `snap install RjAgguCDAawLSJ3IByPe0R92xlNtrfGt_219.snap`.
