Can you give the exact error message please.

Also how did you upgrade to 19.01? Or tried upgrading

sory in polish but your name is polish.
Upgrade is done
version in KDE system info and hardinfo is 19.01 but build version is still 1803
in grub is still version 18.03

Build version will not change that is normal.
You can edit the version number if you want in /etc/lsb-release /etc/os-release and /etc/xdg/kcm-about-extendedrc

However I would recommend to leave it as is.

When it comes to the artwork-grub-theme-netrunner-black package. It seems like it does not want to overwrite the file.
You can force it by executing

sudo dpkg -i --force-overwrite /var/cache/apt/archives/artwork-grub-theme-netrunner-black_1.0+p20181001+git20180515.1352_all.deb

If it throws out any other error please attach the english version of the error output.
You can achieve that by setting LC_ALL=C as variable in the terminal.
So export LC_ALL=C in terminal and all executed commands will output in english.

dpkg -i --force-overwrite /var/cache/apt/archives/artwork-grub-theme-netrunner-black_1.0+p20181001+git20180515.1352_all.deb

Seems like the package is broken anyway. Maybe it is the best to just remove this package for now.
I’ll investigate meanwhile if the package is really broken.

edit: Investigation done.The package seems to be ok. So it must be your installation that might be slightly broken. So the tip to remove this package alltogether with the command

sudo apt purge artwork-grub-theme-netrunner-black
and then reinstalling it with

sudo apt install artwork-grub-theme-netrunner-black

should work.
