## Keyserver lookup endpoint used to fetch PPA signing keys.
## Like host_keys.yml, this file exists so that a static endpoint is data,
## updatable in one reviewable place, instead of hardcoded in the source —
## the URL was previously duplicated in the apt keyring and release
## modules. Sparse on purpose: it grows if keyserver pools or alternates
## ever need to be tried.
##
## The template carries its variable part as a {fingerprint} placeholder,
## substituted by the accessor of src/apt/keyring.rs with plain string
## replacement.
##
## Where the value comes from: keyserver.ubuntu.com, Ubuntu's OpenPKS
## (formerly SKS) keyserver; op=get with search=0x<fingerprint> is the
## documented machine interface fetching one key by fingerprint
## (https://keyserver.ubuntu.com).
