No installer support for WPA Enterprise-secured WiFi networks, crashes

[qwach]

The installer doesn't give you a full Network Manager prompt when asking to connect to WiFi networks, only a password field (Kubuntu 13.10). This is insufficient for connecting to WPA Enterprise-secured networks. I decided to just try out what happens when you enter a password and try to connect anyway - boom, crash.
Entering a live session, activating the connection there and installing afterwards obviously works, but should be unnecessary.

Fixing bug 1107935 (implementing WPA Enterprise) would be one way of preventing the crash, but not the only way.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[System76 (salmon76)]

This bug is confirmed on several System76 computers, including our Meerkat 2 (meer2) desktop, our Lemur 6 (lemu6) laptop and our Gazelle 10 (gaze10) laptop using Intel 8260 and 3165 WiFi cards. From the attached oem-config.log, it looks like there is no error handling for WPA2-Enterprise WiFi access points. Ubiquity then crashes without creating the user.

I have added a patch to https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1107935 that will fix this issue
