How do I fix the malformed line from my source.list?

I was trying to download the wine hq, but when I tried to download it, something happened to my computer. After I failed to install wine, I always encountered the same problem when I write this command: sudo apt-get update, or just
apt-get update.
The problem is that I receive this message in my terminal.
E: Malformed entry 60 in list file /etc/apt/sources.list(Component) E: The list of sources could not be read. From there, I cannot use any apt-get command...
Could you fix this problem?
I used the command sudo more /etc/apt/sources.list to get the lines for the source.list
In my source.list, it says the following:

# deb cdrom:[Ubuntu-MATE 20.04 LTS _Focal Fossa_ - Release amd64 (20200423)]/ fo
cal main multiverse restricted universe

I hope this information helps to find the malformed entry.
I am new to linux, so it is very hard for me to find what to do...

It looks like there is an extra linebreak within the first line:

# deb cdrom:[Ubuntu-MATE 20.04 LTS _Focal Fossa_ - Release amd64 (20200423)]/ fo
cal main multiverse restricted universe

should be

# deb cdrom:[Ubuntu-MATE 20.04 LTS _Focal Fossa_ - Release amd64 (20200423)]/ focal main multiverse restricted universe

line 60 needs a space before focal

deb https://dl.winehq.org/wine-builds/ubuntu/ focal main

Do you know how to use the vi editor? if yes, :set number will display numbers so you can see the issue with line 60 (missing a space between ubuntu/ focal main). Two lines down, it is correct.

If you dont know vi, let's use xed (another editor, go to Edit>prefs>Display Line numbers)

sudo xed /etc/apt/sources.list ... fix line 60, File, Save, Exit
then sudo apt update, it should be clean.

Hi, thank you for your help.
Because I am beginner in linux os, I don't know what "vi" is.
Also, I don't know how to get to "xed".
The command sudo xed /etc/apt/sources.list doesn't work for me.
It says that xed command cannot be found. How to you go to the Edit>prefs>Display?

Kevin, seems you dont have xed as an editor. But, I think you have pluma editor on your system.
sudo pluma /etc/apt/sources.list
Pluma shows the Line number at the bottom of the window. Go to line 60 and add that space. Save, Exit, and test again that sudo apt update is clean (w/o errors)

@kay_boy Maybe it should be deb not dep. Seems you're trying to install the atom editor.
The first line of /etc/apt/sources.list.d/atom.list should be

deb [arch=amd64] https://packagecloud.io/AtomEditor/atom/any/ any main

See https://flight-manual.atom.io/getting-started/sections/installing-atom/#platform-linux

Fix the error, then sudo apt update should not give errors. If it does, post the errors here.

E: The list of sources could not be read.

I have been having this issue for some time now and i have tried all the above to no avail. Please help me out. I am new to all this. Thank you

you can remove that file from /etc/apt/sources.d/ dir

but my question is, are you on focal (20.04 or groovy (20.10)?

There is a recommended way to install wine5.
