You are not doing it wrong :) The revert command "blacklists" this particular snap revisions on purpose, so that you don't reupdate to it. However, there is a way to get back to it! You can remove explicitely that revision (without removing the current snap). Data associated to the reverted revision will be cleaned up as well. Then, you can refresh. In a concrete example with the hello snap: 20 is the revision in the stable channel, 29 corresponds to the revision in the beta channel. # Install and update $ snap install hello $ snap list hello Name Version Rev Developer Notes hello 2.10 20 canonical - $ snap refresh hello --beta $ snap list hello Name Version Rev Developer Notes hello 2.10.1 29 canonical - # Revert $ snap revert hello $ snap list hello Name Version Rev Developer Notes hello 2.10 20 canonical - # Remove reverted version (and associated data) $ snap remove hello --revision=29 hello removed $ snap list hello Name Version Rev Developer Notes hello 2.10 20 canonical - # Reupdate $ snap refresh hello --beta $ snap list hello Name Version Rev Developer Notes hello 2.10.1 29 canonical - I hope that answer your questions :) Cheers, Didier -- Snapcraft mailing list Snapcraft@lists.snapcraft.io Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/snapcraft
