Comment 6 for bug 1941799

This is stuck in -proposed due to some test failures.

a. snapd's autopkgtests are failing. I'm not sure why but it's failing against a bunch of stuff, and unlikely to be related to openssh. For this, I think just wait until snapd gets sorted.

b. openssh's autopkgtest for armhf fails:
