Thank you for your bug report The log has those errors
'kernel: ERROR @wl_set_key_mgmt : kernel: invalid cipher group (1027076) wpa_supplicant[1263]: wlan0: Association request to the driver failed' There was a similar error mentioned in that upstream commit https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/commit/2f8a4e90 Could you maybe report it upstream on gitlab? they will probably have a better clue about the issue -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1879905 Title: Can no longer connect to Ubuntu WPA hotspot after upgrade to 20.04 Status in network-manager package in Ubuntu: New Bug description: I upgraded my Ubuntu client to 20.04 and could continue to connect to my WPA Hotspot running on an Ubuntu server. Upon update of the server to 20.04 I could no longer connect with any of my various client OSs. After using the updated network-manager from https://bugs.launchpad.net/ubuntu/+source/network- manager/+bug/1870359, I can now connect to the hotspot from all of my machines running many flavors of OS (Windows, MacOS, Android, Ubuntu 19.10), but I cannot connect from my machine running Ubuntu 20.04. If I turn off the encryption on the hotspot or turn on WEP encryption (using nm-connection-editor), then I can connect. Seeing that my client running 19.10 can connect, I'm not sure if this is a problem specif to my particular laptop running 20.04, or if it is rather a problem that any client updating to 20.04 will have. I will update my other 19.10 machine, that is currently working with the WPA hotspot, to help differentiate between these two possibilities.
