Link points to a passing build.

That test was reliable on the old s-jenkins CI system, and hasn't changed in months. It's using dbusmock-qt5 in an uncontroversial way. No idea why it fails now. dbusmock-qt5 issue?

Fixed the link. The test doesn't fail on CI, but rather on builders, so it might be simply a timing issue.

Link still pointing to good build.

"Process [python3] for service [com.canonical.powerd] failed to appear on bus" - dbustest-qt5 tries to bring up a mock dbus server, and the unit test sits and waits for it to appear. The wait time is 30 seconds, which should be more than enough (like, a second or 2 is needed at most).

I'll ask Pete Woods to comment further, in case he has ideas

I mis-spoke, wait time is 5 seconds. That might be too short, will propose MP increasing it
