Can't connect to internet if second user session

[Facundo Batista]

My kid was using the laptop, connected to internet in his user session.

I switched to my user (but his session was still active), and NetworkManager couldn't connect to internet.

Error from syslog:

Thank you for your bug report. Is your user an admin one (what's the output of the 'groups' command)?

Which type of connection did you try to activate and how? could you try if you get the same issue under GNOME?

[Facundo Batista (facundo)]

Hello Sebastien,

I'm admin, yes. `groups` gives me: facundo adm cdrom sudo dip plugdev lpadmin lxd sambashare

I did not try to activate any specific connection: it's just NM trying to connect to one of its saved WiFis when starting the session.

I don't have gnome to try it.

Data point: after several attempts in error, it ended up connecting to WiFi... maybe the other connection in the other session did some kind of timeout?

[Sebastien Bacher (seb128)]

Could you add the 'journalctl' log from the session where you had the issue/retry/worked?

[Facundo Batista (facundo)]

Attached since I opened the laptop lid until it got working by itself.

Thanks!!

[Sebastien Bacher (seb128)]

it seems to be a wpasupplicant / driver issue, from the log

[Facundo Batista (facundo)]

@seb128, shall I open this bug anywhere else too? Thanks!

[Sebastien Bacher (seb128)]

not needed, I'm reassigning this one to wpa now
