apt signing keys should be .pgp files (not .gpg) #2087
Description
In Debian Trixie the signing key files used by apt are not actually .gpg files. FWIW gpg can still generate the key files from .asc files but a specific gpg option must be used as the default will generate a key file that apt can not use.
The common bootstrap_apt conf script in the 19.x-dev branch is already building the correct key files, however the files still have a .gpg file extension.

Tagged as a 'wishlist' feature as this is related to consistency with Debian rather than a "real" bug.
