Denis,
Me (personally) could do this. But then I rather dislike doing any [additional] filtering on a router as this could cause issues in the future… It also blocks other snap’s and potential more (not sure what all would be at the same location)
Another (in my opinion simpler) solution is to download the snap and install it locally - not from store.
But what I’m looking for is a solution for the USER of my snap. Something which is kind of automatic or can be set by the snap maintainer to accommodate a different update policy. Something which would probably download a new snap and give a warning/notice of a new snap available, but does NOT install it until a “ok” is given by the user.
We are currently getting close to release a new major version, but I haven’t updated the snap in weeks as I know I’ll cause network outages at various places just by pushing a new snap into the store.
My current (unfortunate) way is to just NOT push any new versions to the snap store until this is resolved or there
is a major security issue I need to address (but not for new major versions)
