Hi,
I’ve never paid attention to the fact that Nextcloud is upgrading itself. When I first installed it, it was 19.x.x and now I’m at 20.0.8. Because I use E2EE and everything is working well with the new 3.2 client, I don’t want to move to version 21 yet. How can I stop the Snap from automatically updating my server when it is released?
Thanks.
Hi, unfortunately is this not possible, afaik.
You can find a statement regarding this topic by the snaps maintainer here: Disabling automated Nextcloud-snap refresh · Issue #327 · nextcloud/nextcloud-snap · GitHub
But what you might be able to do, though, is to file a new issue here: https://github.com/nextcloud/nextcloud-snap/issues/new/choose and ask if it is possible to wait with the NC21 update until the E2EE app is compatible with this version.
Thank you.
You are welcome!
Here are also some docs regarding snapd updates. Maybe they are of some use for you:
tl;dr you want this command:
$ sudo snap refresh nextcloud --channel=20/stable
Not true, thankfully. This exact use-case is one that we carefully considered. Here’s a blog post about exactly this for when v12 came out, which had a number of issues:
https://kyrofa.com/posts/nextcloud-snap-to-be-updated-to-v12
Combine that blog post with the current set of release channels:
https://github.com/nextcloud/nextcloud-snap/wiki/Release-strategy
And I give you the following command:
$ sudo snap refresh nextcloud --channel=20/stable
Voila, you will get v20 releases, but never upgrade to v21 until you’re ready, at which time you can:
$ sudo snap refresh --stable nextcloud
That will get you back on the “just keep me up to date” train, or you can be more conservative with:
$ sudo snap refresh nextcloud --channel=21/stable
Which will, as you should be able to guess, keep you on v21 releases.
Thanks for reminding me that there is a way, I’ve just forgotten about the channel functionality 
Thank you both! I will take care of this right now.
