After migration from gpg2 to gpg21 and getting and signing some
new certs I've noticed the following error message.
What is the right path to remedy the situation?
LANG=C gpg2 --check-trustdb
gpg: enabled debug flags: memstat
gpg: keyring_search failed: Legacy key
gpg: failed to rebuild keyring cache: Legacy key
gpg: marginals needed: 3 completes needed: 1 trust model: PGP
gpg: depth: 0 val [..]
LANG=C gpg2 --version
gpg (GnuPG) 2.1.11
dpkg -s gnupg2
