Bug description:
[SRU] 2.71:
https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/2118396
This issue was originally reported to be a snapd issue, however there
is no definitive fix on the snapd side to guarantee that another user
service that depends on seeding to be complete, does not start too
early. For this reason the recommendation was made to change the boot
sequence for the other service, and this is the definitive fix that
was made to livecd-rootfs (Ubuntu).
On the snapd side, some work was done to improve seeding speed, but
this is not in any way a definitive fix, it just decrease the
likelihood of encountering the problem on a slow system.
https://github.com/canonical/snapd/pull/15682
[ Impact ]
This issue is only relevant to Questing installer ISO that performs a
hybrid install.
When another service starts up and depends on snapd seeding to be
done, without enforcing a boot order that ensures seeding is complete
(e.g. `After=snapd.seeded.service`), snaps will be missing and this
will lead to failures. This is the case for the installer ubuntu-
desktop-installer.service.
[ Test Plan ]
Confirm that the definitive fix made for livecd-rootfs (Ubuntu) solves
the problem.
---original---
Upon booting an ISO (I believe this may only happen with slow internet
connections) there is (sometimes) NO snaps installed. Snapd is
functional but snap info list lists no snaps. The desktop installer
services crashes, and thus the installer never boots up. After *quite*
some time (approx 5m) on this live iso, snaps were installed, and the
installer icon then functional. I've attached the journalctl to help
debugging.
