Hello,

I just enable “builds” on my snap on snapcraft.io. But all build fail with this error message :

Running pull phase...
Failed to find extension 'gnome-3-28': a extension by that name does not exist.
Check the extension name and try again.

Just tried on local computer (Archlinux x64 - Manjaro), snap creation works like a charm.

Any idea how fix issue on the remote build ?

2

Seems like the same issue as in Build.snapcraft.io build failing due to ancient snapcraft, @wgrant any ideas here?

this has been pinpointed to a new rollout done on the webfront where they are incorrectly setting the “channels” which forces the default to use the deb.

Is something i can fix/use a workaround on my side ?

5

A fix has been pushed to https://snapcraft.io - can you try again and let me know if the error still happens? Thanks.
