You don't have to censor out public keys ... – Artur Meinild Mar 29 '23 at 17:13
For unsigned repositories you could try `sudo apt update --allow-insecure-repositories`. It will bypass the error saying the repository is unsigned. – Arjun K Shibu Mar 29 '23 at 17:27
The WineHQ pubkey error is a well-known issue. – Artur Meinild Mar 29 '23 at 17:53
