I see that other people have permission issues with trying to update from 10.0.1. Regular installs are getting /var/www/ permission issues, my Nextcloud box software is spitting out /snap/nextcloud/ write permission issues.
I was hoping at this stage updates would be as simple as clicking on the Update button.
The solution is to wait until the snap package is updated. Server update notifications are a little confusing and could do with being disabled for snap users.
I think the snap will update itself without notification …
That’s the magic of Ubuntu Core : “Snaps are faster to install, easier to create, safer to run, and they update automatically and transactionally so your app is always fresh and never broken.”
