While developing a snap I will often use snap try to test things out under confinement. Occasionally I'll forget to uninstall before rebooting and because the snap's prime directory is in my encrypted $HOME snapd won't be able to find it at next boot and the snap will be marked as broken. snap remove understandably returns an error saying that the snap is not mounted and therefore cannot be removed cleanly.
How do I clean up this broken snap?
The easiest way I've found to clean up this snap is to run snap try on the same directory again. This causes snapd to perform the mount operation again and puts the snap in a reasonable state from which you can continue testing or remove the snap cleanly.
