Troubleshooting "DEAUTH_LEAVING" error when connecting to WPA2-Enterprise network after Linux upgrade

Question

I'm not able to solve this error

[  666.695694] wlan0: deauthenticating from xx:xx:xx:xx:xx:xx by local choice (Reason: 3=DEAUTH_LEAVING)

I obtain the error only when I'm trying to connect to a WPA2-Enterprise network (EAP-MSCHAP2). Other connections work well without any error.

This error has been obtained after a Linux upgrade, currently I'm using

Linux root 4.18.0-kali2-amd64 #1 SMP Debian 4.18.10-2kali1 (2018-10-09) x86_64 GNU/Linux

Lurking I've seen a possible cause to this problem: the TLSv1.2 support has been disabled. I've seen several solutions with wpa_supplicant, but I'm using NetworkManager. I've also tried to configure wpa_supplicant without any result.

What can I do?

Ummm......network manager is just a front-end for wpa_supplicant. Debian even took the words right out of my mouth: "NetworkManager is also a front-end for wpa_supplicant." https://wiki.debian.org/WiFi/HowToUse#wpa_supplicant — bgregs, Dec 06 '18 at 21:25
Ok, but I don't have a wpa_supplicant.conf file and all my network configurations are in in /etc/NetworkManager/system-connections. All "workarounds" found are based on a modification of wpa_supplicant.conf — Rtmd, Dec 07 '18 at 09:05
Maybe I'm wrong but I've understood the problem but I'm not able to find a solution — Rtmd, Dec 07 '18 at 09:07

Not a duplicate: I don't have an interface with a long name. My interface is the standard wlan0 — Rtmd, Dec 08 '18 at 09:20

I have the very same problem. wpa_supplicant not connecting anymore to eduroam

We should try to figure out what package update introduced this bug and either revert it to the previous version or fix it.

Update: I found that the 25th of november libssl got updated in debian testing/unstable to version 1.1.1a-1. wpasupplicant, instead, hasn't been updated since August.

I tried to downgrade both and actually the problematic one is wpasupplicant. Try to install the older version by:

sudo apt-get install wpasupplicant=2:2.4-1+deb9u2

then mark it hold with:

sudo apt-mark hold wpasupplicant
