Missing final newline

I'm very new to everything here and only got ubuntu today. Also I have no clue how to use the bit that makes it clear its code so apologies. I am trying to install git for a project and it says this:

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies.

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

So I ran:

sudo apt --fix-broken install

and got this:

dpkg: unrecoverable fatal error, aborting:
 files list file for package 'qemu-block-extra' is missing final newline
E: Sub-process /usr/bin/dpkg returned an error code (2)

Can anyone help? I know other people have this problem but with different what I'm guessing is the package (like I said, I'm new), where mine says quemu-block-extra.

Please dumb it down as much as possible for me.

Спасибо всем, это была проблема с поврежденной SD-картой.
