I am a beginner on Linux so I don't know what went wrong but the Software Center wont open anymore, if I click it it will open and close immediately. Also, on the top bar it will appear the message on the attached picture. error message

Now I cannot install any application, it wont let me install it from the terminal because it will says "Unable to correct problems, you have held broken packages." or "Type '“deb' is not known on line 59 in source list /etc/apt/sources.listE: The list of sources could not be read."

    Did you edit your sources.list manually?

  • Is there a way to know if I did ? I don't really remember, I was trying to install Firefox and Libre Office, so I was following some post that I found on line.

    Could you post the contents of your /etc/apt/sources.list file here? This should help us resolve the problem.
