Probably, these settings are cleared when you force a network-manager restart. Try
sudo service network-manager restart
Still a rather brute solution but one level better than pc restart. If it works, it can be automated by putting a script in /etc/NetworkManager/dispatcher.d with contents:
if [[ "$2"="vpn-down" ]]; then
There is an issue with the kernel using in 20.04 with the driver you are needing so i suggest you to try to update your kernel, here is a tutorial
If you already have the needed kernel just jump to the fourth step
First you must uninstall all privative drivers you have(Nvidia,ATI(AMD)) mostly your video drivers this is just to prevent future troubles and ...

To connect to the old samba server add one more option to your smb.conf - above the others you have above:
client min protocol = NT1
If you want to have the older machine access the Ubuntu 20 server you need to add SMB1 support on the server end:
server min protocol = NT1
Then restart smbd: sudo service smbd restart
Reason: The version of Samba in Ubuntu ...
I had the same error. Pinging IP addresses worked, but no DNS resolution. Outside of WSL everything was fine. The problem was caused by OpenVPN for me, when I disconnected from my workplace's VPN, the error was gone.
I don't know if you figured this out already, but I think you have the syntax wrong. The first line should be:
myscanner.udi = esci:networkscan://192.168.1.123
You have the prefixes backwards. I don't think you need the port number unless it was changed.
No. The format of /etc/hosts is very simple and doesn't allow for complex pattern matching:
This manual page describes the format of the /etc/hosts file. This file is a simple text
file that associates IP addresses with hostnames, one line per IP address. For each host
a single line should be present with the following information:
You need to upgrade packages in your system or install Ubuntu 18.04.4.
Connect to the internet using your phone and run
sudo apt update
sudo apt install linux-generic-hwe-18.04 linux-firmware
That will save time and traffic, instead of sudo apt upgrade.
Problem solved with the helpful input from the user Pilot6 - not really sure how I can thank her/him.
The key was to connect the Lenovo Yoga C940 laptop to an Android cell phone via a USB cable, which established what Ubuntu saw as a wired connection to the internet.
Once connected to the internet, I ran
sudo apt update && sudo apt upgrade -y
For me it was flushing the dns cache that way:
sudo systemd-resolve --flush-caches
You can then check the statistics in order to make sure that your cache size is now zero.
sudo systemd-resolve --statistics
You should be able to see what goes where using the route command. It will tell you what IP addresses get routed where. Here is a common example:

Use sudo systemd-resolve --revert --interface vpn0 to reset resolv.conf after getting off the VPN.
If that works, you can run it automatically when disconnecting from the VPN by creating /etc/network/if-post-down.d/vpn0 with the following contents:
if [ "$IFACE" = "vpn0" ]; then
systemd-resolve --revert --interface vpn0
Forticlient is not available through ubuntu repository. You can download (as of now 6.4 version) and install manually by executing below commands in terminal.

sudo dpkg -i FortiClientFullVPNInstaller_6.4.0.0851.deb
Ok so while writing the above question I had a thought that I had added the new SSD into my build without taking anything out (I have a few backup HDD's still in there). Unplugging these HDD's fixed the problem so I suspect it was a PSU issue.
Yes, is the bottom line answer.
There have been a lot worse takedowns of major systems without passwords... so needless to say, with a password???
They will need, things like username, and access through services you may or may not have enabled. (ftp,ssh,http,rdp,or so on)... so it is 50/50 on that front...
But one would have to believe if someone obtains ...
By default ubuntu comes with no password. If somebody knows your private IP on that WLAN connection they could definitely SSH into your system. However, even if you did set a password and somebody knows it, they will still be able to ssh in your system. If they do NOT know your password, then not really! I hope this answered your question!
so apparetnly it cannot resolve the DNS address. I would recommend trying to set the dns address to 18.104.22.168 which is google's dns address. You can do that by typing the following. Make sure to change the System eth0 to your connections name. You can check the name of your connection my running the first command.

The driver from rtlwifi_new repo doesn't build with new kernels any more.
You need to install another driver this way:
sudo apt install git dkms
git clone https://github.com/lwfinger/rtw88.git
sudo dkms add ./rtw88
sudo dkms install rtlwifi-new/0.6
This way you won't need to re-install the driver after kernel upgrades.

I can reproduce your error. You created a paradox.
client max protocol = NT1
Samba disables NT1 on the server side of your install yet you specify the maximum protocol the client can use to NT1. Ain't gonna happen.
I'm almost certain you meant to add this in smb.conf:
client min protocol = NT1
If I do that and restart smbd: sudo service smbd restart I can ...

No, there is no specific setting for that.
First of all, make sure you are using a wired connection and not wireless.

If it's already boken then you don't really have anything to lose and even then most devices will paise untill they have wifi again

The information/answers provided by others are correct, you cannot reset NM and persist a connection. You have to address the root cause of your problem.
I've found that many Wifi related issues can be resolved by disabling the power management.
Here's how I do it:
Enable: chmod +x /etc/network/if-up.d/wifi-...
When you restart the network manager all connections are gone, so there is no way to avoid downtime. However, what you can do is to connect to a LAN, configure the LAN with iface. This would likely let you stay connected while you restart the network manager. If it does not, you can configure a static route to divert all traffic to LAN first.

NetworkManager only connects to a network of you have a profile for it. And NetworkManager does not create profiles, also because it wouldn't know which settings to you.
