@G.S.1 here’s the roadmap Niemeyer promised! Nice to have it all laid out BTW, interesting to look at :slight_smile:

A post was merged into an existing topic: 2.28 release cycle started

2 posts were merged into an existing topic: Introducing base snaps

This has been on the list for about three months now, could a dev maybe make a topic on it? :slight_smile:

Yeah, coming soon! This is the next major feature we’ll work on as soon as we finish some of the current large changes we have in progress.

I see “Auto install of content snap dependencies”, what that means ? it will work like .debs or maybe snaps will search among other snaps installed in the system?

The content interface supports a default-provider attribute holding a snap name. That is the default provider for that interface, meaning that if snapd does not see any other snaps in the local system providing a content interface with the same content label, it will fetch that snap.

The auto-connection rules are still used to define whether to establish that connection or not. In other words, either it needs to be a snap from the same publisher, or the content provider must be a reviewed request that got auto-connections enabled for it.

That constraint exists to improve the stability of the snap ecosystem as a whole, by making sure that either the publisher is the same or that the person publishing a snap with content for everybody is aware of the stability requirements.

None of that is similar to deb or rpm packages.

Thanks for answer. :slightly_smiling_face:

I changed the order of the roadmap so that the most recent release is on top. I hope this increases the readability.


Having a ‘previous stable releases’ folding spoiler might help so that people see edge/pre-edge (2.35), then beta (2.34), then stable (2.33), then a ‘previous stable releases’ dropdown, then upcoming and backlog (so as to help people see upcoming and backlog more easily without stopping the display of previous versions’ new features) but formatting doesn’t work properly in dropdowns. I’ve filed a topic about this on Discourse Meta.

I would like to know about this topic and for that reason I am going to ask the following questions. Since I can understand differently what is discussed in the topics, in addition to not being a programmer or similar, for that reason I pose the following questions: When you talk about snap download, does it mean that I can download some application.snap? If that is the case, how will that app.snap be installed? with the software center? from the terminal? Or none of the above?

did you coinsider clicking on the (topic) link to know more about it ?

There’s a typo in this line, should be “met” and not "meet at the end.

fixed - thanks for letting us know.

Version 2.53.2 of the snapd snap is already in stable, any plans on updating this? Thanks!
