Public bug reported: PPAs are third party repositories. for security reasons, PGP keys for these must not be placed in /etc/apt/trusted.gpg.d, according to this document:
https://wiki.debian.org/DebianRepository/UseThirdParty they should instead be saved to /usr/share/keyrings and the generated .list file for the repo added should refer to its particular key by using a [signed-by=/usr/share/keyrings/...] argument. this ensures that the downloaded PGP key will only be used to verify a particular repository and is not globally available to verify package lists of all configured repositories (as are all keys found in /etc/apt/trusted.gpg.d). please fix add-apt-repository accordingly.
