console-conf crashes with a WiFi which does not support SIOCGIWESSID

[Simon Fels]

console-cofn crashes with "PermissionError: [Errno 1] Operation not permitted" when I have my TP-LINK TL-WN725N V2 plugged via USB in the device. If the device is unplugged console-conf does not crash anymore.

See attached log file for more details.

Sounds plausible. I hate everything.

fix, what do you think?

@Michael: That sounds like a first attempt to fix this but I guess we will then miss the ESSID in the UI for those dongles. The problem seems to be more that the driver does not support the necessary WEXT command SIOCGIWESSID anymore and just gives you access with nl80211. So we have two real options to fix this:

1. Force all kernels to have CONFIG_CFG80211_WEXT enabled. As this is the official pi2 kernel we should definitely open a bug there and get it included in the kernel config.

2. When the WEXT ioctl fails fallback to nl80211 or use nl80211 directly and fallback to the WEXT ioctl

This bug was fixed in the package subiquity - 0.0.24

---------------
subiquity (0.0.24) zesty; urgency=medium

  * Rework network model and UI significantly, using rtnetlink nl80211 events
    to provide a live view of the state of the network as it changes.
    (LP: #1627031, #1624322, #1637153)
  * Show friendly message instead of getty when only ssh login is possible.
    (LP: #1639543)
  * Hide keypresses while in the "press enter to configure" screen.
    (LP: #1639917)
  * Give a hint on how to create a store account. (LP: #1639799)
