Messed up my sudo apt update

Question

I seem to have messed up the sudo apt update command in Terminal.

sudo apt update:

E: Invalid value set for option Signed-By regarding source https://downloads.plex.tv/repo/deb/ public (not a fingerprint)
E: The list of sources could not be read.

cat /etc/apt/sources.list:

E:

I'm just starting to figure out Ubuntu (complete beginner).

Can someone please help me understand what I've done and how I can fix this?

I have updated the question with the output but the output was blank — Armir Saraci ASaraci, Nov 30 '22 at 21:07
Use the GUI "Software &Updates" instead. The additional sources you added are at Other... tab. Remove the one mentioned in your error message. — ChanganAuto, Nov 30 '22 at 21:10
@Nmath - I have update the question, the result does not change — Armir Saraci ASaraci, Nov 30 '22 at 21:32
@ChanganAuto - i have tried that as well, but it is not opening and am not able to remove the file mentioned in the error message — Armir Saraci ASaraci, Nov 30 '22 at 21:33
Does this answer your question? How do I restore the default repositories? — Artur Meinild, Dec 01 '22 at 07:29

First you need to add key for Plexmedia server. You can do it by executing below command in terminal.

curl https://downloads.plex.tv/plex-keys/PlexSign.key | sudo apt-key add -

You need to generate source list file which is messed up.

You need to edit /etc/apt/source.list file and place below content for Ubuntu 22.10 version. You can do it by executing below command in terminal.

sudo nano /etc/apt/source.list

Place below content in editor and save it.

###### Ubuntu Main Repos
deb http://archive.ubuntu.com/ubuntu/ kinetic main restricted universe multiverse
Ubuntu Update Repos
deb http://archive.ubuntu.com/ubuntu/ kinetic-security main restricted universe multiverse

After that you should able to run sudo apt update without any error.
