How to copy from VIM?

Question

linux

I'm using VIM on Linux, but I can't get it to copy all lines to another program.
I need to open a file in VIM, select it, copy it, and paste it, for example, into LibreOffice with the standard function keys ctrl-v
In VIM, it turns out I need to configure Ctrl-A, Ctrl-C

If you share the setting of the key in .vimrc, I will be grateful.

Understood.
You need to install vim-gnome, in my case
sudo apt install vim-gtk3
After that, you need to configure keyboard shortcuts in vimrc
