Some programs [software updater+welcome+boutique] are not working

Hi.
I'm virtually new to ubuntu and I ended up some troubles whence I tried to install wine on ubuntu mate. After all, wine has not been installed and some of my programs such as software updater, welcome, and boutique don't run.
Is there anybody know what should I do to solve this problem?
Thank you in advance.

Hi

ended up some troubles whence I tried to install wine

what happens if you open a terminal like mate-terminal and run this command

sudo apt install wine

I notice your sentence reads
nor some of my programs such as software updater, welcome, and boutique do run

I am guessing you did not mean to use "nor"?
unless you mean you can not run those software apps?

after entering that command I see this:
[email protected]:~$ sudo apt install wine
[sudo] password for kianoosh:
E: Malformed entry 54 in list file /etc/apt/sources.list (Component)
E: The list of sources could not be read.
E: Malformed entry 54 in list file /etc/apt/sources.list (Component)
E: The list of sources could not be read.
And as I said I can't run aforementioned programs.

Since Welcome/Boutique/Software Updater use Apt for software installations, it makes sense that would fail to start because of that error.

To fix:

  1. Find this file in the file manager (Caja) and navigate to :harddrive: File System → etc → apt.
  2. Right click sources.list and choose "Edit as Administrator".
  3. Jump to line 54 and remove it. Save the file.
  4. Open the Terminal (CTRL+ALT+T) and run:
    sudo apt update
    

By default that file has about 51 lines, so malformed entry at the end is likely from an external repository. If you'd like us to double check, please post us the output of /etc/apt/sources.list (Be sure to post it in :code: tags)

Thank's a lot.
The problem has been solved by your help.
This is the content of that file after removal of line54.
