@arkhamvm did you try the suggestions: change the number from -100 to 0 see if that helps, also check /etc/NetworkManager/system-connections I think it should be empty or have only 1 connection to your VPN. what was the result?
@arkhamvm ok It seems that in github.com/KDE/plasma-nm they are talking about openvpn, question, was your openvpn installed before upgrade, is it possible for you to remove it, restart your computer and then reinstall Openvpn?

@amar only come back home, will try now. Yes, I can reinstall openvpn, but don't know how it may helps..
@amar change the number to 0 and sudo apt purge openvpn and sudo reboot now has no effect.
@amar sudo apt purge openconnect and sudo reboot now didn't helps too

ok try uninstalling vpn restart install it again
The github link that you sent me said it was part of openvpn
ah ok, do you have the githubs program without openvpn
@arkhamvm can you see the connections there?
arkhamvm
arkhamvm
Already reinstalled.
I don't think that network widget is a problem. Because I see this connections via `nmcli connection show`

@arkhamvm something either you installed or in your settings is causing that, I do not know what atm, my kubuntu has no such connections

manpages.ubuntu.com/manpages/focal/man4/…
So this is a Virtual Ethernet Devices, any ideas how to check what/who added them?
amar

I thin you have ethtool, I`ll have to check it takes a while, can you check that you have it?
just run ethtool -h
@arkhamvm and you changed the number to 0 did it still disconnect?

arkhamvm
arkhamvm

arkhamvm
arkhamvm
And I don't have this connections before upgrade (from 22.04.4)
amar

I know, but when you upgrade a lot of packages change, have you tried sudo apt update and sudo apt upgrade no problems there?
arkhamvm
arkhamvm
11:03
Yes, I also completly reinstall kde-full and plasma
amar
amar
@arkhamvm ok check /var/log/dist-upgrade/main.log see if you can find a package that has gone wrong
arkhamvm
arkhamvm
cat /var/log/dist-upgrade/main.log | grep ERR and cat /var/log/dist-upgrade/main.log | grep WARN is empty
amar
amar
@arkhamvm ok, you can also read phoenixnap.com/kb/ubuntu-fix-broken-packages, I will get back to you
@arkhamvm ah, do you have anything else beside openvpn that affects network?and senad me a pictuire of your openvpn and lo in the same way you sent the picture of your wired, you can also check ip 4 and ips tabs of your openvpn to see if anything pops out
arkhamvm
arkhamvm

Oh. I found from where it comes. It is Docker virtual network
If I run docker compose down connections is go away

Ok I thin I found the answer superuser.com/questions/1307030/… first use the script to bring them down if everything is ok you can delete them but I would wait a day before deleting them
Ah ok, then solved?
arkhamvm

gist.github.com/lanrat/458066dbdeb460b9cef40dc2af639a24
I'll try this config now
amar
amar
ok, I have to go eat I will be back in 1 hour
arkhamvm
arkhamvm
```
[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=false

[device]
wifi.scan-rand-mac-address=no

[keyfile]
unmanaged-devices=interface-name:docker*;interface-name:veth*;interface-name:br-*;interface-name:vmnet*;interface-name:vboxnet*

```
Yeah, it's works!
So, it's obvious now, NetworkManager.conf cleared by system upgrade, but docker package was not reinstalled
Please post this as answer, I'll accept it.
I appreciate the time you've spent

@arkhamvm great, finally you got it working and thanks, I have updated the answer, it might change a little since I asked a person who takes care of all answers to take a look at it.
