This may be related to a WPA security fix present in Oracular. It's related to PEAP authentication, but I'm not really sure if that is the root cause.
This is the upstream fix https://w1.fi/cgit/hostap/commit/?id=8e6485a1bcb0baffdea9e55255a81270b768439c And the wpa source package changelog from Oracular: https://launchpad.net/ubuntu/oracular/+source/wpa/+changelog Can you get the wpa_supplicant logs with "journalctl -u wpa_supplicant.service" and look for any lines with PEAP authentication errors? In particular the line below, which is part of the patch: EAP-PEAP: Server indicated Phase 2 success, but sufficient Phase 2 authentication has not been completed ** Tags added: rls-oo-incoming -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2084553 Title: system cannot to connect to wpa2-enterprice PEAP mschapv2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/2084553/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
