Issue encountered during installation attempt.
I follow this guide and execute sudo apt update, but then encounter an issue. The error states a signature verification problem, indicating the repository isn't updated and it's using old index files. The GPG warning mentions a missing public key.
Looking at the provided link would reveal the answer to your issue. In your situation, it's described as "jammy," not "focal."
The issue indicates a missing source file for WineHQ Jammy on the system.
I ran the wget command and the other instructions, then executed sudo apt update which triggered these issues:
E: Conflicting values set for option Signed-By regarding source https://dl.winehq.org/wine-builds/ubuntu/ jammy: /etc/apt/keyrings/winehq-archive.key != /usr/share/keyrings/winehq.gpg
E: The list of sources could not be read.
The same issue appears when attempting to execute sudo apt update
For pop_os you might need additional procedures. Refer to the guide at the provided link.
The update failed because there are conflicting key settings for Signed-By. The source URL points to a different key file than the one expected. This also prevents reading the list of available sources.
