不幸的是我在运行时遇到以下错误
$ gpg2 --refresh-keys
gpg: refreshing 18 keys from hkps://keys.openpgp.org
gpg: keyserver refresh failed: General error
正如你可以从上面的收集，我已经配置了密钥服务器是hkps://keys.openpgp.org在~/.gnupg/dirmngr.conf所建议的在这里。这是完整的内容~/.gnupg/dirmngr.conf：
keyserver hkps://keys.openpgp.org

debug 4096
debug-level 4096
debug-all
log-file /tmp/dirmngr.log
gpg2 --refresh-keys在pkill dirmngr给出这个之后再次运行/tmp/dirmngr.log
