Sorry if I was unclear, but could you run this after you have waited 10 minutes? All I see from the plot there is that it took snapd 3 minutes to seed and that I don’t see console-conf ran yet, but what I would like to see is a plot where console-conf was eventually run on the serial getty so we can see if something else got blocked waiting for that to run
Okay, I reinstalled and waited 10 minutes. This was all I got. It only goes to 380 seconds.
Hmm so what that implies is that the getty is ready at around 3min (and this is confirmed by the above systemd-analyze critical-chain serial-getty@... output), but it for some reason does not output the message to run console-conf by “Press enter to configure” until 7 minutes later. Is that correct ?
If so, then this sounds like a console-conf bug. I would refer you to bugs.launchpad.net/subiquity and to @xnox specifically

IIRC in core18 console-conf was changed to actually wait until snapd marks the system fully seeded …
Gotcha. One remark that I posted about earlier, just so that we’re all on the same page, is that I tried @ogra’s suggestion of disabling console-conf and saw the same behavior, this behavior (now that I’ve updated to Kernel 5.4) being this output on first boot. This is the symptom indicating problems to me:

This takes about 7 minutes to get through.
Sorry your comment is a little confusing, you say you disabled console-conf, but in the log you pasted below, console-conf still runs, hence the Press enter to configure. message at the bottom. Was this log from a run with console-conf enabled, in which the Press enter to configure. message shows up after 7 minutes?
Ah my bad, so I have two boxes of identical make, and on one, I did the normal procedure, waited 10 minutes, and then pasted the log and the systemd-analyze. On the other I did was @ogra suggested.
Did you file a launchpad bug? If so please leave a link here, but I am lost as to where your 4 minutes are going on this device.
