More trouble installing Wine

[Kevin Perez]

Hello Everyone,

I am hoping to eventually install Zello on my computer. In order for this program to work, it requires Wine. I tried following the instructions for installing Wine by:

• dpkg --print-architecture
  
• sudo add-apt-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/focal main'
  
• Received error message: " E: Malformed entry 55 in list file /etc/apt/sources.list (Component)
  E: The list of sources could not be read."
  
• Opened Menu->System->Package Manager
  
• Enter Password and Press Authenticate
  
• Received error message: "E: Malformed entry 55 in list file /etc/apt/sources.list (Component)
  E: The list of sources could not be read.
  E: _cache->open() failed, please report."
  
• Pressed "Close" button
  
• Reported all of this to you
  

Given all this, how may I finally install Wine? What woudl you recommend I do about the error messages. I have already tried using cat /etc/apt/sources.list. It produces:
"# deb http://us.archive.ubuntu.com/ubuntu/ focal main restricted

# deb http://us.archive.ubuntu.com/ubuntu/ focal-updates main restricted

Unfortunately, I am novice enough to be clueless about what this tells me. Perhaps it offers you some clue. Thank you for reading this post. I very much look forward to having Wine (whatever version you recommend) and Zello up and working on this computer. Thank you in advance for your assistance.
