I tried to download something by adding a domain to my sources.list, I didn't know how to save it properly so I closed my terminal and I ended up with a lot of different versions for the same file but I don't know which one should I delete.
I also want to remove that domain since it can't connect to it and it throws an error every time I run sudo apt update.

Here is a screenshot of the various files:

And here is a screenshot of the URL that gives me an error:

Thanks!

It's a BAD idea to be adding non-Debian repos to your sources.lst. This basically defeats one of the main security/integrity features of GNU/Linux.

I know, but how do I install something that's not on the Debian repository? I know I can install software with .deb but sometimes there's no option for that and I have to install from the terminal.
I'm downloading FLOSS stuff BTW, the only proprietary thing that I have installed is Steam.

Meh... I wouldn't worry too much about Steam. I haven't run Deb in many years, but when I did, I would compile non-Deb apps from source or install binaries to /opt. Of course, neither of these methods is recommended by the "Debian Way", the Debian Philosophy.

Anyway, if there are not .deb downloads on the sites where you're searching for certain applications, you'll be forced to use other methods. There are MANY Debian users here at LQ.org. Please stand by for some more useful information and tips from them.

Luck with it... and have a great weekend!

From your screenshot the source line is invalid. Looking at the site you did not include what version of Debian to use.
Your line just says "Debian_" no version number that I can see.

For the multiple files, look at the one with the ~ on the end. The file size is 0, so is safe to delete.
I see you were using Vim to edit, read up on on the .swo and .swp files here: http://ttm.github.io/research/2017/1...m-swp-swo.html

...have a good look at all the .list files under /etc/apt.

Show us the output of
Read this.

No, I know Steam is not going to install any kind of malware or security issue.

I don't know how to compile non-deb apps or how to install binaries, I should check that out. And I know it's not recommended but Debian repository is kinda limited, it doesn't even have Oracle VirtualBox which is a pretty common software and it's FLOSS.

Thanks, you too have a great weekend!

Mmm, okay, I don't want to install it anymore, so I should go to the /etc/apt/sources.list and delete the source line, right?

Great, I'll delete the one with "~". I don't want the content within the .swo and the .swp files, since it is the same that's in the normal file but with the source line that doesn't work. Is it safe to delete them? I read the link you provide me but I'm not sure I understood everything.

I have taken a good look at the .list files, so what? I still don't know if it's safe to delete those.

The second URL I provided has a screenshot of the output of that command. I have already read about that, I trying not to fuck it up but since I'm a noob it's complicated. Thanks!
