core18 snap missing from bionic desktop, snaps fail to seed offline

[Dimitri John Ledkov]

core18 snap missing from bionic desktop, snaps fail to seed offline

yet gnome-logs etc depend on core18

Note the livecd-rootfs in bionic does not have snap-tool and is not using it.

Possibly we need to force seed core18 manually somehow.... or backport the snap-tool improvements to bionic. Going with that route.

[Testcase]

* build ubuntu desktop
* check that it has core and core18 seeded as deps of the snaps
* check that there are no other changes to the snaps seeded
