Network Manager issues

[jimlambe]

Having recently updated from 19.19 to 20.04, I am now unable to add/edit any connections. When I try, a dialogue box pops up saying;

"Failed to activate {SSID}
Not authorized to control networking."

I have spent some time trawling the web but no obvious solution was found, but one post mentioned "nmcli g permissions" which I tried as user and using sudo.

User output;

PERMISSION VALUE
org.freedesktop.NetworkManager.enable-disable-network no
org.freedesktop.NetworkManager.enable-disable-wifi no
org.freedesktop.NetworkManager.enable-disable-wwan no
org.freedesktop.NetworkManager.enable-disable-wimax no
org.freedesktop.NetworkManager.sleep-wake no
org.freedesktop.NetworkManager.network-control auth
org.freedesktop.NetworkManager.wifi.share.protecte d no
org.freedesktop.NetworkManager.wifi.share.open no
org.freedesktop.NetworkManager.settings.modify.sys tem no
org.freedesktop.NetworkManager.settings.modify.own auth
org.freedesktop.NetworkManager.settings.modify.hos tname auth
org.freedesktop.NetworkManager.settings.modify.glo bal-dns auth
org.freedesktop.NetworkManager.reload auth
org.freedesktop.NetworkManager.checkpoint-rollback auth
org.freedesktop.NetworkManager.enable-disable-statistics no
org.freedesktop.NetworkManager.enable-disable-connectivity-check no
org.freedesktop.NetworkManager.wifi.scan unknown

Sudo output;

org.freedesktop.NetworkManager.enable-disable-network yes
org.freedesktop.NetworkManager.enable-disable-wifi yes
org.freedesktop.NetworkManager.enable-disable-wwan yes
org.freedesktop.NetworkManager.enable-disable-wimax yes
org.freedesktop.NetworkManager.sleep-wake yes
org.freedesktop.NetworkManager.network-control yes
org.freedesktop.NetworkManager.wifi.share.protecte d yes
org.freedesktop.NetworkManager.wifi.share.open yes
org.freedesktop.NetworkManager.settings.modify.sys tem yes
org.freedesktop.NetworkManager.settings.modify.own yes
org.freedesktop.NetworkManager.settings.modify.hos tname yes
org.freedesktop.NetworkManager.settings.modify.glo bal-dns yes

org.freedesktop.NetworkManager.enable-disable-statistics yes
org.freedesktop.NetworkManager.enable-disable-connectivity-check yes
org.freedesktop.NetworkManager.wifi.scan unknown

Now it seems to me that I should have more permissions as a user. How do I fix this issue?

Within the Network widget, there is a check box for 'Allow all users to use this connection' (or similar). Ensure that it is checked.

All my existing connections always have that option set and have checked they still are. This seems to be a system level permissions issue. Worked totally happily over at least 3 distro updates but this one got screwed somehow.

I have just checked what the user permissions are when you boot into a live version of Kubuntu 20.04 and all the permissions when checked at User level are set to "yes". So I would venture that this is the issue, now all I need to find out how to re-set these permissions.

Here are my user permissions:

Here is what systemctl status NetworkManager showed:
