Repository error

[gshockxcc]

I'm trying to run 'ifconfig', but I don't have it installed. When I run

sudo apt install net-tools

I get an error that the IP address isn't found for the repository:

Err:6 http://us.archive.ubuntu.com/ubuntu groovy Release
 404  Not Found [IP: 91.189.91.39 80]
Err:7 http://us.archive.ubuntu.com/ubuntu groovy-updates Release
 404  Not Found [IP: 91.189.91.39 80]
Err:8 http://us.archive.ubuntu.com/ubuntu groovy-backports Release
 404  Not Found [IP: 91.189.91.39 80]
Err:9 http://us.archive.ubuntu.com/ubuntu groovy-security Release
 404  Not Found [IP: 91.189.91.39 80]
​

This is followed by instructions (i think), which I don't fully understand.

E: The repository 'http://us.archive.ubuntu.com/ubuntu groovy Release' no longer has a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
​

Any suggestions or explanations would be greatly appreciated.

20.10 went EOL (End-of-Live) on July 22, 2021. The repositories for that release aren't maintained anymore, so any attempt to poll them for packages is going to fail with 404 Not Found.

What is the solution when that happens? How would I install net-tools? I assume that I can use a different method. I'm just not sure what that would be without the repositories.

You could try to install the net-tools version from 20.04 via .deb, which is still available:
http://security.ubuntu.com/ubuntu/po...ntu1_amd64.deb
No guarantee that this will work…
The .deb from 22.04 will probably depend on e.g. a newer libc6 than is available in your 20.10.

I think generally you should either consider using an LTS-release of Kubuntu or upgrading your system every 6-9 months in the future.

Ideally? You would want to reinstall, and use an LTS release that will stick around for more than 9 months.
You don't have a good upgrade path, since the only one to go to is also End of Life.
22.04 will be supported until 2023 on the Kubuntu parts, and the OS level parts until 2027, for example.

BUT.....all is not lost. They don't quite nuke all the old repos, the just mothball them.
You just need to edit your sources to point to where they have been archived.

You can follow the very first strep shown in this doc:
https://help.ubuntu.com/community/EOLUpgrades
You are just changing the 'us.archive.ubuntu.com' to 'old-releases.ubuntu.com' where needed.

Goodness, I sure hope you aren't regularly browsing thew web with stuff that's two and a half hears old

Well, actually ... yes, I am. See, this is how little I know about Linux/Kubuntu. I have only dabbled for the last 15 years. I never had time to invest like I do now. Based on all the versions I saw on the forums, I figured that people installed a version and stuck with it. I upgrade so infrequently that by the time I have to do it again, i have forgotten how. Hence, I'm in the "New Guy" forum.

An outdated web browser is bad not matter the OS, just be careful

But for you , the Long Term Support versions are ideal, since these only come out every two years and have a better shelf life in terms of OS and security updates.
You don't need to upgrade so often.
Newer releases are better at giving warnings about this, which helps, too.
22.04 is a bit less than year old, so no full OS upgrade needed till 2024., when the next LTS is out. Otherwise, you need to upgrade the OS every 6 months.

An outdated web browser is bad not matter the OS, just be careful […]

If I may: Everything outdated can be bad as soon as a computer is connected to the internet (or exchanges data with other foreign computers), regardless of the operating system!
Of course you are right: a web browser is one of the most obvious pieces of software.

So keep your systems up to date, folks - especially with security fixes and if you use computers in a commercial setting!

[gshockxcc]

Thanks to all for the responses. I have been using the Brave browser, and keeping that up to date regularly. I use Firefox less frequently, but still update it as needed. That said, thanks to all for the education.

Much of net-tools is outdated and not maintained anymore.

if it's ifconfig you want to use, try ip instead, and for one other common command netstat is now ss.
