Ubuntu Core automatically updates installed snaps, for example 'core' snap, and to return to previous version I need to run the command

snap revert 

But I want to control this myself and update manually only.

How to disable autoupdate of concrete snaps or disable this feature systemwide?

P.S. I have read the documentation here on developer.ubuntu.com , but my system distribution of Ubuntu Core 16 on Raspberry Pi does not have a snappy command. How do I disable autoupdate without the snappy command?

  • Hmm, that page you link says that this autoupdate can potentially reboot my system. I definitely don't want that. – Organic Marble Feb 24 '17 at 15:06

    Do you know how to disable autoupdate completely ? – Andrey Germanov Feb 24 '17 at 16:08
  • No, I would like someone to answer your question. I installed the snappy command from the link you provided, but it seemed to be some video app. So I'm confused. – Organic Marble Feb 24 '17 at 16:23
  • The link needs fixing – Gert van den Berg Oct 5 '18 at 6:15

You can't disable autoupdate. You can, however, control the update schedule:

snap set core refresh.schedule=<spec>

I can't find an easily-accessible description of the spec (I'll update this answer if I do), but here are some examples:

  • 9:00-15:00 (every day between 9am and 3pm)
  • 9:00-15:00/21:00-22:00 (every day between 9am,5pm and 9pm,10pm)
  • thu@9:00-15:00 (only Thursday between 9am and 3pm)
  • fri@9:00-11:00/mon@13:00-15:00 (only Friday between 9am and 3pm and Monday between 1pm and 3pm)
  • fri@9:00-11:00/13:00-15:00 (only Friday between 9am and 3pm and every day between 1pm and 3pm)
