Bug Description

Live session on i386 has an issue immediately which reports that network-manager indicator crashed

On the installed version it is impossible to connect to the net via wifi

Will check on amd64 but as far as I can tell it is fine there.

Happens here as well, amd64, xenial.

The result is activating an AP from either the indicators or system settings is impossible.

You can reproduce this in a unity 7 live session on the current yakkety daily, for an easy way to poke

Seems easy to reproduce on i386 but not so easy on amd64

After UEFI installation alongside W, indicator-network shows ethernet connection instead of Wi-Fi on first boot, however internet works fine. Tested on amd64 laptop intel+intel graphics+intel wireless 3160

HW Amd+Nvidia graphics+Ralink RT2561.

When installing Yakkety adm64 and just after clicking next from Download updates+Install 3rd party drivers screen, Wi-FI icon gets blank and installation options appear. There is no internet connection. Additionaly, Wi-Fi seems to be unable to reconnect the previous Wi-Fi network

This bug was fixed in the package indicator-network - 0.8.0+16.10.20160930.5-0ubuntu2

---------------
indicator-network (0.8.0+16.10.20160930.5-0ubuntu2) yakkety; urgency=medium

  * data/indicator-network-secret-agent.conf.in: Only start on Unity 8. We
    only start the indicator there; do the same for the secret-agent too. This
    works around a crash on i386 (by not running the code) - the crash is
    still pending investigation. (LP: #1632275)

Reopening, since the crash still needs to be fixed; it just doesn't get run on U7 all the time any more so we don't see it so much.
