Description

Sometimes I can select a Wi-Fi network but then the dialog to enter the password is never displayed. Instead, I see a GNOME Shell stacktrace in the Journal, very similar to those we have attributed to topIcons so far. Disabling topIcons fixes the problem immediately.

This prevents me from doing Buster-related work that’s way more critical than the functionality provided by topIcons, so I’ll disable topIcons on feature/buster until we have a clearer plan on Bug #16608 and friends.

  • Subject changed from topIcons sometimes prevents Wi-Fi configuration on Buster to Wi-Fi passphrase prompt is sometimes not displayed on Buster

I’ve seen this problem without topIcons. Trying to set up the password via GNOME Control Center made it crash, apparently due to a missing package. I’ll investigate.

I’ve fixed the GNOME Control Center part of this bug but the problem remains wrt. the passphrase prompt when selecting a Wi-Fi network via the GNOME Shell interface.

Restarting GNOME Shell (Alt + F2, r, ENTER) seems to fix this problem reliably.

Here’s the Journal for this failure.

#6 Updated by intrigeri 2019-04-03 17:33:11

I’ve seen another failure mode: the modal dialog with the prompt shows up, but neither clicking “Connect” nor “Cancel” has any effect.

I’ve tried a few things in the hope they would fix things, but they didn’t: without TopIcons enabled, without setting an administration password, without MAC spoofing, without ~/.gnome2/keyrings/, and on a different laptop (ThinkPad X200).

But if I restart GNOME Shell (alt+f2) once logged in, before trying to connect to the Wi-Fi, then my first connection attempt works.

I can’t reproduce this bug with a pristine Debian Buster Live image.

Upgrading to GNOME Shell 3.32 from Debian experimental does not help.
