mkdir: invalid option -- 'O'
Try 'mkdir --help' for more information.

It seems like I have a problem with the repository key, but I do not understand the problem or how to find a solution to the problem as well.

thank you in advance for all your help.

Try deleting winehq-archive.key and adding it again.
