What to do if the `snap refresh snap-store` command doesn't upgrade

The snap store is the only place where running snap refresh will not update, because the snap itself or a snap app is still running.

• Make sure you have completely closed the Snap Store. If the Snap Store is still open, the update will not be performed.

Sometimes the Snap Store can run in the background without you knowing. You can check by using the command:

ps aux | grep snap-store

Stop all running Snap Store processes:

sudo killall snap-store

Upgrade snap store

sudo snap refresh

Reboot (to let the snap processes auto-run again)

reboot
