Bug Description

I just upgraded from Artful to Bionic. gnome-initial-setup ran. It asked me if I wanted to enable Livepatch, and I agreed. I believe my Internet connection was working fine at the time. It gave me a username/password prompt. After entering those in it asked me for a 2FA code. After entering that in, I got a spinner with "Connecting..." in the bottom left, but nothing further happens. It's been about ten minutes hung like that.

I tried to click the Cancel button but nothing happened. Then I tried to close the app from the bar on the left (right click -> Quit) but nothing happened.

After the previous actions, netstat reports no TCP connections on IPv4 nor IPv6. It's appears not to be "Connecting" to anything.

Expected: at least some kind of timeout reporting failure so I can progress with any other "initial setup" actions.

A few things about my installation:

I installed this laptop with Artful initially, around the beta1 milestone. I dist upgraded it to Artful after release. Before upgrading to Bionic I made sure it was fully up to date.

apport-bug didn't work. After I click Send, I got no browser prompt to finish my report. This might be because I have an unusual Firefox setup (multiple profiles).

I noticed that I have bionic-proposed enabled. This is unintentional. It seems likely that I had artful-proposed enabled for test purposes previously. I did have a pin deprioritising it, but it refers to artful specifically so doesn't seem to have acted on Bionic, so unfortunately I've ended up upgrading all the way up to bionic-proposed.

OTOH, apport-collect brought up Firefox for authorization just fine.

Though it seems to also have failed to update the bug.

I'm running gnome-initial-setup 3.28.0-2ubuntu6.16.04.2 on Bionic.

Looks like it's hung here:

https://git.launchpad.net/ubuntu/+source/gnome-online-accounts/tree/src/goabackend/goaubuntussoprovider.c?h=applied/ubuntu/bionic-proposed#n882

Is there some kind of error path which is causing the async operation to never complete?

Adding a gnome-online-accounts task as the hang seems to be in there.

Andrea: subscribing you for attention. I don't care about my own system, but if there's an edge error case that isn't handled, then other users might end up stuck too.

If you're around, I can debug further. I don't know if I can reproduce, but I'll try to avoid killing this hung process that I have gdb attached to in case you want me to peek at anything specific.

I was forced to reboot due to a wifi hang so I no longer have the process available. However I can try again to reproduce if you like - gnome-initial-setup came up on next login. I'll wait though in case you want me to instrument anything first.
