Fail to run the command "apport-collect 1960392".
Please check if the sosreport of #1 is enough, thanks.

The issue seems to be in subiquity (server installer) not the linux kernel, per the 'error' screenshot (thanks!)

Marking the subiquity project as affected, and linux as invalid.

So the reason this doesn't work is that the udev data for the container, /dev/md/imsm0, does not contain the keys we look for to work out which devices are part of it. We expect to find keys called things like MD_DEVICE_dev_sda_DEV but they are not there. There is UDISKS_MD_DEVICE_dev_sda_DEV though and this is very strange because the code to produce the MD_DEVICE and UDISKS_MD_DEVICE keys is essentially the same:

IMPORT{program}="BINDIR/mdadm --detail --export $devnode"

SUBSYSTEM=="block", KERNEL=="md*", ENV{DEVTYPE}!="partition", IMPORT{program}="/bin/sh -c '/sbin/mdadm --detail --export $tempnode | /bin/sed s/^MD_/UDISKS_MD_/g'"

I don't know why one use tempnode and one devnode -- maybe that's significant? Or maybe it's a race where the mdadm rules run before the devices is really ready or something. Does this happen every time?

 Does this happen every time?
-->Yes, recurrence rate 100%

This is a duplicate of the linked bug that was filed by the upstream.

It can pass with the latest edge subiquity
