no way to switch ubuntu-core to --edge on images

[Oliver Grawert]

ogra@pi3:~$ snap list ubuntu-core
Name Version Rev Developer Notes
ubuntu-core 16.04.1 526 canonical -
ogra@pi3:~$ sudo snap refresh ubuntu-core --edge
error: cannot refresh "ubuntu-core": snap "ubuntu-core" has no updates available
ogra@pi3:~$

this is a lie, the edge channel currently has version 549 (building an image from scratch with "-c edge" actually installs this version properly) for some reason snapd thinks there are no versions available.

This problem happens frequently on snaps with a large revision history.

The publication of the full revision history is triggered where only the new revs publication should be sufficient.

So, 2 distinct problems, performance and convenience.

Rectifying my previous comment, this problem is not directly related to snaps with large revision history, but instead to all workflows involving isolated push & release (mostly LP auto-builds).

The snap-release endpoint was pushing outdated information to the package index service (empty channel), invalidating the user action (release revision N to channel 'edge', for instance).

This will be fixed in the next store rollout.
