In that text document I just tried highlighting the whole page exept your pc name and copy n paste ( sudo apt-get update and the hit lines)
the full code into terminal it installed some but then syntax error but then I did the first line on it's own sudo apt-get update and it installed some thing. I've just done it on vmware. Give that a try
I'm afraid I didn’t quite understand what exactly I’m supposed to do here…

Yes sorry I'm not experienced on linux. On your link I went to your web page and then I downloaded the text document and opened it. You possibly can copy it from the web because I'm half on the net in windows and vmware with zorin. I copied and pasted everything exept: millann@Milan-PC:~$ and it did install some upto 16. It did however come up with synax errors but that's possibly it can't understand the text bits at the bottom. After I then just typed sudo apt-get update and it did install upto 16. Not sure if it's correct give it a try see how it goes also try sudo apt-get install then your link
You have a duplicate in lines 51 and 52 in your sources.list
What is your output of
cat /etc/apt/sources.list
To fix it is very easy. Open the sources.list file in a text editor and remove the duplicates.
If you can show the output of the above, we can help you ensure you get the right ones.

You can elevate to root:
sudo -i
Launch the file manager
nautilus
In the File manager, on the left side "Other locations"
Then > "Computer"
This will position you in Root.
Double click etc then apt.
Right click on sources.list and select to open with text editor.
Scroll to the bottom and you see;
deb http://archive.ubuntu.com/ubuntu noble-updates multiverse universe restricted main
deb http://archive.ubuntu.com/ubuntu noble-backports multiverse universe restricted main
deb http://mirror1.sox.rs/ubuntu/ubuntu/ noble-updates restricted universe main multiverse

You can see that those three are all duplicated. You can remove the duplicates per line (Or you can hashtag them to comment them out).
They are safe to remove.
When finished, it should look exactly like:
deb http://archive.ubuntu.com/ubuntu noble-updates multiverse universe restricted main
deb http://mirror1.sox.rs/ubuntu/ubuntu/ noble-updates restricted universe main multiverse
deb https://mirror.niif.hu/ubuntu/ noble-backports universe multiverse restricted main
Once done, Save the file and close.
The next time you run sudo apt update, those errors will be gone.

Give them your web link as well it may help
I’m getting too many errors — critical ones — when I try to launch Nautilus. It eventually starts, but when I click on Other Locations, the window freezes and that’s it.

Eh... Gnome and Wayland... they march on.
Instead, try

You want the sources.list
The .save file is a backup file.
Yes, and i removed the duplicated ones and still have a problem
https://limewire.com/d/a7kB8#O4s8JkhyYJ
Hmmm... Was I moving too fast? Apologies for missing details.
This time, I grabbed a copy from post 31 above and cleaned it up a bit.
In your sources.list opened in text editor as before, select all lines and remove them. It should be a blank page.
Then, copy this cleaned up sources.list and paste it in:

Save the file, then test
sudo apt update.
This should deal with the duplicates - we *next need to deal with the trusted key warning. One thing at a time...
