Hello,
So, I'm a noob when it comes to Linux (installed it today) and I wanted to install Wine on it. Everything went ok untill I got to this command :
sudo apt-get install --install-recommends winehq-staging
this error appears
E: Malformed entry 1 in list file /etc/apt/sources.list.d/wine.list (Component)
E: The list of sources could not be read.
E: Malformed entry 1 in list file /etc/apt/sources.list.d/wine.list (Component)
E: The list of sources could not be read.
Can anyone help me ?
Hello, @XrayMan19.
Show us the full, unabridged contents of the file /etc/apt/sources.list.d/wine.list. Otherwise, we have no idea what the issue is.
ALSO: After you paste the contents of that file into a post here, and before you hit the "Reply" button below, please select that text and click the </> button just above the text area. If you don't do that, the sources.list file will be very difficult to read, ideed. Ask me how I know that. 
run this command in the terminal
sudo pluma /etc/apt/sources.listand look at towards the bottom of that file you should see entries that should look like this
deb Index of /wine-builds/ubuntu focal main
#deb-src Index of /wine-builds/ubuntu focal main
My Wine list are on the main sources.list not in the sources.list.d folder
I used these instructions without issue.
One difference is that these intructions use:
sudo apt install --install-recommends winehq-stable
I think I managed to repair it myself. The problem was that the word"main" was on the second row, not the first near the other text
deb https://dl.winehq.org/wine-builds/ubuntu/ focal main
Also if u dont mind could u check my source.list so you can see if I screwed up any other files? Thnaks in advanced!
