ubuntu resolute Release does not have a Release file

[JoshiFresa]

Hi,

I installed ffmulticonverter in Kubuntu kernel 26.04 using those advised commands

sudo add-apt-repository ppa:ffmulticonverter/stable
sudo apt-get update
sudo apt-get install ffmulticonverter

But I finally removed it later, using this command:

sudo apt-get --purge autoremove ffmulticonverter

After that I tried to throw the directory containing the app to the trash but it did not let me do so. I was surprised but I forced trashed it though.

After that when I opened Discover to see updates I saw an error message that is also repeated in the terminal when I type sudo apt update:

Ign:4 https://ppa.launchpadcontent.net/noobslab/apps/ubuntu resolute InRelease
Err:5 https://ppa.launchpadcontent.net/noobslab/apps/ubuntu resolute Release
404 Not Found [IP: 185.125.190.80 443]

Notice: Missing Signed-By in the sources.list(5) entry for 'https://ppa.launchpadcontent.net/noobslab/apps/ubuntu'

I'm not sure if the noobslab is related to ffmulticonverter or not but I then tried to repair the issue, by looking up the web for solutions and used this command:

sudo add-apt-repository --remove ppa:nooblap/apps/
sudo apt-get update

And I get this same result:

So I'm not sure what this means exactly yet and how to deal with it. Ideally since I removed the app I guess the idea would be to remove it but how? Also some are suggesting to mess with this:

Modify the PPA entry in the sources.list file:
sudo sed -i 's/noble/focal/g' /etc/apt/sources.list.d/xyz-ubuntu-ppa-noble.list

I looked at it but I don't know what I'm dealing with so I prefer to open this ticket. I just moved from Windows to Linux so don't expect me to understand even mildly advanced tech stuff of linux. I'm learning. Thanks in advance for your help.

sudo apt-get update
sudo apt-get install ffmulticonverter

How is that even possible? There is no way to install the at best 12-year-old packages from there in 26.04. there is no 26.04 (resolute) reposiotory there.


Your PPA does not provide any packages for 26.04.

And the noobslab PPA you added is also truly ancient and dead, last used in 2018. Only look at how-tos that are specific to your exact *buntu release, and as recent as you can find.
https://launchpad.net/~noobslab/+archive/ubuntu/apps

Same for the old and dead ffmulticonverter
https://launchpad.net/~ffmulticonver.../ubuntu/stable

I have no idea what you mean here.

But, since you added the PPA, which was already dead and never provided any software to you, the PPA removal commands don't know what to do.

However, all you need to do here is find the correct file referencing noobslab in /etc/apt/sources.list.d/ and delete it.

Modify the PPA entry in the sources.list file:
sudo sed -i 's/noble/focal/g' /etc/apt/sources.list.d/xyz-ubuntu-ppa-noble.list

No, just no, do not follow any random things you find on random websites. Seriously.

Just stick with apps you find in Discover, until you learn a bit more about how things work.

I'm a beginner in Linux. I wasn't aware that if an app is old it can even cause an issue to the system. In Windows if an app is too old, it usually does not even let you install it, with some dialog box popping up, so you don't get into trouble to start with. Now I'm also learning that a PPA has to have "packages" to install in a given distro or kernel. That helps to understand the error. And so I did not execute the command from this random site and instead asking here for help as stated above. You're mentioning to remove the correct file referencing noobslab in etc/apt/sources.list.d to delete it but I need more help to do just that, since what I see in this folder does not really mention noobslab. I'll add a screenshot to show what I see. I don't know what I'm supposed to see there and what this directory is about, how to remove it, or if it will give me permissions to do so.

What I see in the sources.list.d folder

Moving to the correct subforum.

So this is an upgrade, then? From which release?
Maybe a little more specific info on what you have done here, specific commands, actions, and webpages, if you can.

That first file you must have created or edited in some fashion.

So post the contents of this, as well as the ubuntu.sources file.
Also post the contents of /etc/apt/sources.list if it has any URLs in it.

We are looking for reference to the url in your error messages. Normally, adding a PPA creates its own file, which is easier to manage, and doesn't damage or mess up your standard sources.

Slightly OT first, because it is important:

[…]

You shouldn't do something like this in any operating system - one cannot stress this enough!

The only exception IMHO: you cannot install this specific software from your operating system's "software store",
a) you know that the website/the author of the program is trustworthy and
b) the software is intended for your operating system and the version of you operating system.

Otherwise "all bets are off" and - worst case - anything could happen (also in Windows which is not different at all in this regard - you can't imagine how many botched Windows systems I have seen in the last 30 years, because people have installed something they found on some website or gotten from a friend…).

• You wouldn't try to install brake pads (from an untrustworthy dealer) for a 2015 Nissan Leaf in a 2020 Ford F150, would you?

If you cannot find a specific software in a "software store" in Linux you also have the good possibilities to additionally use the Snap Store or Flatpaks from Flathub.
But the same applies there: don't install anything that is not trustworthy, meaning verified by The Snap Store or by Flathub!



Back to your problem:

The only thing I can see in your output where the error could possibly come from is moved-from-main.sources - you could paste cat /etc/apt/sources.list.d/moved-from-main.sources here. And please use <CODE> tags.

By the way: there is a typing error in sudo add-apt-repository --remove ppa:nooblap/apps/ in your first post.



PS: Sorry for the delay / that I had not seen claydoh's post in time - I had to cook lunch while I was occasionally typing…

Lol I was cooking a quick chili for a late dinner when I eventually finished my post.
