Bug Description

Story: while running console-conf test plan I tried this with different sd cards and always get the same result. Once I type a wrong SSID or password for my wlan, it never returns a wrong SSID message, it keeps thinking and if I try to cancel it crashes rebooting console-conf.

Environment:
latest candidate image on db
- snapd 2.23.1
- candidate: 16-2 (1444) 69MB

Steps:

1º Flash db image from http://cdimage.ubuntu.com/ubuntu-core/16/candidate/
2º Boot core and press enter a couple of times to get to networking
3º Select wlan0
4º Type a wrong wlan SSID, the right password and press done
5º In networking page press done again

Expected result: console-conf returns a message about bad settings or bad config
Current result: it keeps thinking without returning any information and crashes when trying to cancel the process

Add info: once console-conf reboots there is no issue if you try with the correct configuration for your wlan

I wanted to provide better feedback about this sort of thing but it's surprisingly difficult.

That said, crashing is definitely unexpected! Can you post the console-conf log file (/var/log/console-conf/subiquity-debug.log from the SD card) somewhere?

Pressing done in network connections page without applying any wlan config, and then trying to cancel it also reboots console-conf

So what was going on here was that the configuration was supposed to time out after 30s, but it wasn't thanks to a bug. Canceling the configuration after that 30s had expired led to the crash.

I can confirm this is working now with latest image from candidate on dragonboard. I went through all the console-conf tests regarding misstyped SSIDs/passwords and everything is ok.
