Wifi stopped working (failed to connect to socket /run/dbus/system_bus_socket)

Xilanaz · May 16, 2026, 9:31am

hi,

I updated my mothers laptop this morning and her wifi stopped working afterwards.

the update was from 7.0.1 (about 2 weeks ago) to 7.0.6 this morning
if I go back to previous kernel (advanced, select 7.0.1) it still wont work
if I go back to a snapshot before the update it works
I hope I included all the needed logs, I did notice a Failed to D-Bus activate wpa_supplicant service in the networkmanager logs so I added the wpa_supplicant service too. if feels like its a rights issue but well not sure how to solve it.

duh !
and I thought lets post in network and i looked here and… sigh nm, thanks for the link

nick_battle · May 16, 2026, 10:30am

Confirming that this is a problem, and that hui’s workaround of disabling the AppArmor service works for now.

hui · May 16, 2026, 10:33am

No, i didn’t recommend to disable AppArmor. Disabling AppArmor isn’t a solution but a really bad decission. There are actually two senseful recommendations atm. Either downgrade AppArmor or adapt the service override file.

nick_battle · May 16, 2026, 10:38am

Okay, apologies. There are better options that disabling AppArmor, as you say.

Lachu · May 16, 2026, 11:55am

I see running this by hand works:

# First terminal
# /usr/sbin/wpa_supplicant -c /etc/wpa_supplicant/wpa_supplicant.conf -u -t -f /var/log/wpa_supplicant.log
# next, second terminal
 systemctl restart NetworkManager
# Do not close any of these terminals!

Inside /usr/share/dbus-1/system-services/fi.w1.wpa_supplicant1.service

User=root

NickLion · May 16, 2026, 12:23pm

I still think downgrade is a better option than fix just wpa_supplicant, as there are other problems with AppArmor 5, like not working lsusb.

Lachu · May 16, 2026, 3:25pm

Packages from here: https://download.opensuse.org/history/20260511/tumbleweed/repo/oss/x86_64/ works.

Add this URI as repo (without last URI part - x86_64/), run Yast2, search for apparmor, select older version (4.x) for each package with apparmor- prefix, install, click continue/backward, set do not change (by right click and select given menu item) on each downgraded package, click ok.

paulcee · May 17, 2026, 1:54pm

Perhaps a stupid question, but where exactly is the service override file? Hesitant to shove in an older repository to downgrade one package.

Also, disabling apparmor at least lets you get online so you CAN add/modify a repository. The ‘fix’ of disabling/rebooting does at least give a temporary fix.

Xilanaz · May 17, 2026, 2:17pm

https://bugzilla.opensuse.org/show_bug.cgi?id=1265380

In the first comment under workaround
I downgraded, it’s not like apparmor v4 is suddenly useless now v5 is out, so rather did that. Also was some USB issues so not just wifi

Lachu · May 17, 2026, 7:04pm

You do not have to disable apparmor. My suggestion was to ran wpa_supplicant as root (on my machine it works) and restart NetworkManager. Downgrade apparmor then and reboot.

nick_battle · May 18, 2026, 10:52am

The fix for this is now available in apparmor 5.0.0-2.1. A zypper dup from the standard repos should pick that up.

paulcee · May 18, 2026, 2:28pm

Can confirm this update fixed things. Apparmor working with zero wifi issues.

I see problem with lsusb probably still persist. Is there any other thing, which would not work?

Working for me now, I believe AppArmor was updated again.
