so i had a problem with winepak it keeped saying gpg signaturs found but none are in the trusted keyring then i looked at a tutorial to fix that problem i tried it until i typed flatpak remote-add --if-not-exists winepak https://dl.winepak.org/repo/winepak.flatpakrepo it showed a error mesage saying Can’t load uri https://dl.winepak.org/repo/winepak.flatpakrepo: Unacceptable TLS certificate can someone please help me thanks.
The solution to this issue is out of our Hands, as the certificate for the Winepak Repository has not been renewed by the developers (expired sometime in July 2020).
I would highly recommend you to not use Winepak anymore, as it seems no longer under active development. If you want to run Windows Applications use some solution which is actively developed, like PlayOnLinux or Lutris - both of them can run applications despite their heritage as a tool for running games in Linux.
