Posting the error log here as I'm unable to install the updates.

In order to offer a solution, it is usually necessary to understand how the system got into the state it is - hence the request for the method used.

'just downloaded it from the Internet' obviously didn't work for you, but it is very difficult/impossible to help using the information provided.

Re-check that the installation instructions you used are from a reputable source and are valid and recent. If they are, then double check that you correctly executed them.

Looks like you've added the Wine repository at some stage, how did you do this?

I just downloaded it from the internet. Nothing new. I wanted to install MT5 Terminal and, it won't install unless I downloaded Wine Repository so, I did it and, it still didn't install. By the way, do you have a solution to my problem?
