From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I don't know which network manager Ubuntu uses, so I'm not sure whether this applies to you. I'm using Arch with the network manager
systemd-networkd. I set it up manually from the CLI by creating a so called.networkfile in the/etc/systemd/network/folder.To "setup" and start using
systemd-networkd, dosudo systemctl enable --now systemd-networkd.service. You will probably also need to setupsystemd-resolvedwithsudo systemctl enable --now systemd-resolved.servicebecause some services and/or programs need this for domain name resolution.Then, check out point 3.5 on this page in the Arch Wiki: https://wiki.archlinux.org/title/Systemd-networkd
Use the section that applies to your setup depending on whether you are wired, wireless or both.
This of course assumes that Ubuntu doesn't use another network manager.
Here is a list of common Linux network managers if the above wouldn't apply.
