A couple more problems with the error mails:
-
They refer to setup/gui, but latest snapcraft tells you to use snap/gui instead:
https://snapcraft.io/docs/deprecation-notices/dn3 -
The “blocked by manual review” one points you to https://myapps.developer.ubuntu.com/ but that seems to have moved to https://dashboard.snapcraft.io.
Also there are some different ways of getting a .desktop into a snap now, see this other thread: Staging a .desktop and icon from a part repo into meta/gui
…but manually including meta/gui/foo.desktop seems to be the one thing that doesn’t work for snaps.
