Bug Description

I've just flashed clean images of OTA-11 from the stable channel onto a BQ Aquaris E4.5 (krillin) and a Nexus 4 (mako). In both cases the phones can see the wifi networks but can't connect to any of them any more.

The wifi networks continue to work for non-Ubuntu devices.

Also, forcefully flashing a device with OTA-10 fixes the problem. The regression began in OTA-11.

What is the config of the wifi networks you can't access (ie, if security is enabled, what sort, etc)

also, when you say flashed clean, was it wiping all user data?

so far others have tried flashing and found no issue so far.

Yep, ubuntu-device-flash touch --wipe --bootstrap ... I can't tell you the network config now as I'm not near it.

Same failure on two unrelated devices while the rest of the wifi network kept working. The same devices were previously happy on OTA-10.1

@daniel are the passphrases on those devices particularly long?

Pat:

Yes the wifi password is 19 characters with lots of different character types but nothing you won't find on a US keyboard.

I just got back from a month away, flashed OTA-11 on mako and have the same problem. Ubuntu Touch, and only Ubuntu Touch can't connect to wifi anymore.

Workaround:
Flash the OTA-10 image first and set up wifi in OTA-10 which works. Then when you upgrade to OTA-11 over the air for real, the wifi config will continue working in OTA-11.

So the problem is just that a raw phone shipped with OTA-11 can't connect to wifi when configured in the wizard or network indicator.

Confirmed the same behaviour on two devices; both mako and krillin now:

OTA-10 WORKS
OTA-11 FAILS

The workaround is to install OTA-10 first and configure wifi under OTA-10. Then you can upgrade to OTA-11 and it will keep working.

If I had to guess, it looks like OTA-11's regression is that it's mis/interpreting the punctuation characters in my wifi password when I enter it. Whereas OTA-10 correctly treated it as a raw string, and then once stored to disk remains correct during future upgrades.

Actually duplicate bug 1589489 seems to explain it.

The fix is currently in silo 005, and was just marked 'Lander Approved'.

The version containing the fix will be 1.2.2-0ubuntu1~xenial3, and should hopefully land in the next few days.

Added an 'Ubuntu RTM' task for network-manager to be clearer about where the fix lands ( ie. in the overlay PPA, not the archive ).
