dirmngr 2.2.19-3ubuntu2 (arm64 binary) in ubuntu focal

 dirmngr is a server for managing and downloading OpenPGP and X.509
 certificates, as well as updates and status signals related to those
 certificates. For OpenPGP, this means pulling from the public
 HKP/HKPS keyservers, or from LDAP servers. For X.509 this includes
 Certificate Revocation Lists (CRLs) and Online Certificate Status
 Protocol updates (OCSP). It is capable of using Tor for network
 access.
 .
 dirmngr is used for network access by gpg, gpgsm, and dirmngr-client,
 among other tools. Unless this package is installed, the parts of
 the GnuPG suite that try to interact with the network will fail.
