Managing automatic updates

Nextcloud snap is designed to update (refresh) automatically by default. You have full control to manage if and when your Nextcloud snap is updated with snapd daemon! See managing updates.

NOTE

Snaps update automatically, and by default, the snapd daemon checks for updates 4 times a day. Each update check is called a refresh.

Updates can be set to occur on Friday at midnight, or for specific days of the month, such as only the third Monday, or even the last Friday of the month, between 23:00 to 01:00 the next day. They can even be postponed indefinitely, or for a set period of time.

When, if, and how often, these updates occur is the job of the snap refresh command.
