Thanks Polytropon for your reply.
I am seeing this issue with these image as are (by only installing `git` and no other alterations made to the OS whatsoever):
Should those be considered as standard installation?
Maybe it is related to keyboard layout as when I press Del key in text editor or command line, I get tilde (~) sign instead of getting character at cursor deleted (so I use Backspace for deletion which works perfectly fine)?
