After applying a snapper rollback, the CLI tool is unable to update again. Here, e.g. where I rolled back to TW 20250218 after being on 20250222, it will not update anymore:
phoenix@racetrack-7290:~> sudo tumbleweed update
choosing latest version
already on 20250222
phoenix@racetrack-7290:~> sudo tumbleweed status
latest : 20250222
target : 20250222
installed: 20250218
Here, since installed is clearly < than target or latest, tumbleweed update should run the update again.
