@queerthoughts@tech.lgbt that little eduroam paragraph boils down to two possibilities:- the NetworkManager profile should be set to be readable&writable only for root (so chmod 600 profile, the location for profiles is usually /etc/NetworkManager/system-connections/) so NM/wpa-supplicant don't complain about secrets being "world readable"- the authentication fails due to a crypto suite mismatch, since OpenSSL 3 disabled all vulnerable protocols and you need to override that behaviour by setting on NetworkManager to authenticate using TLS 1.0 or TLS 1.1, explained further on this other troubleshooting page: https://wiki.archlinux.org/title/NetworkManager#WPA_Enterprise_connections_fail_to_authenticate_with_OpenSSL_%22unsupported_protocol%22_error
