Error sending key - Исправление ошибок и поиск оптимальных решений проблем

Hello,

I can’t send keys from gpg command line, I can search and recv without problems.

gpg --keyserver hkp://keyserver.local --recv-keys 23E89FACE47CC132 -> Works
gpg --keyserver hkp://keyserver.local --search-keys 23E89FACE47CC132 -> Works
gpg --keyserver hkp://keyserver.local --refresh-keys -> Works
gpg --keyserver hkp://keyserver.local --send-keys 23E89FACE47CC132 - Fails
gpg: sending key 23E89FACE47CC132 to hkp://keyserver.local
gpg: keyserver send failed: No data
gpg: keyserver send failed: No data

Tried with hkp and hkps, same results

The server is proxied by nginx, here the config file:

    server {
        listen 0.0.0.0:80 default_server;
        listen 0.0.0.0:11371 default_server;

        server_name default_server;
        server_tokens off;
        proxy_set_header X-Real-IP       $proxy_protocol_addr;
        proxy_set_header X-Forwarded-For $proxy_protocol_addr;

        location / {

            client_max_body_size 8m;
        }
    }

    server {

        location / {
            proxy_pass         http://127.0.0.1:8888;

            proxy_ignore_client_abort on;
            client_max_body_size 8m;
        }
    }

If I post the key with the webpage’s form works fine, I can receive the mail and validate it without any issue.

пытаюсь следуйте инструкциям в http://packaging.ubuntu.com/singlehtml/ создать deb пакет для некоторых программ…

Я должен был начать с генерации ключа GPG

$ gpg --gen-key

затем загрузите открытую часть вашего ключа на сервер ключей

$ gpg --send-keys --keyserver keyserver.ubuntu.com 12345678
gpg: sending key 12345678 to hkp server keyserver.ubuntu.com
gpg: keyserver timed out
gpg: keyserver send failed: keyserver error

попытался добавить порт 80, потому что я читал что-то о брандмауэре, блокирующем эти запросы

gpg --send-keys --keyserver hkp://keyserver.ubuntu.com:80 C58C1F62
gpg: sending key C58C1F62 to keyserver.ubuntu.com:80
gpgkeys: no keyserver host provided
gpg: keyserver internal error
gpg: keyserver send failed: keyserver error

пробовал другие серверы, которые я нашел поиск этих ошибок на net

$ gpg --send-keys --keyserver sks-keyservers.net:80 12345678
gpg: sending key 12345678 to keyserver.sks-keyservers.net:80
gpgkeys: no keyserver host provided
gpg: keyserver internal error
gpg: keyserver send failed: keyserver error

$ gpg --send-keys --keyserver  pgp.mit.edu:80 12345678
gpg: sending key 12345678 to pgp.mit.edu:80
gpgkeys: no keyserver host provided
gpg: keyserver internal error
gpg: keyserver send failed: keyserver error

тоже пробовал

gpg --send-keys --keyserver  keyserver.pgp.com:80 12345678
gpg --send-keys --keyserver  keyserver.sks-keyservers.net:80 12345678

(на случай, если мне понадобится «сервер ключей»)

все с той же ошибкой.

что мне не хватает ?

обновление: изменен порядок опций и добавлен hkp: protocol — и я все еще там, где начал — с небольшим улучшением в сообщении

$ gpg --keyserver hkp://pool.sks-keyservers.net --send-keys 12345678
  gpg: sending key 12345678to hkp server pool.sks-keyservers.net
  gpg: keyserver timed out
  gpg: keyserver send failed: keyserver error

Edit: я прочитал, что отсутствующий хост сервера ключей может быть неправильным сообщением, на самом деле это означает, что ключ не существует на сервере… Но если я отправлю его, конечно, его не будет.

gpg --send-keys --keyserver keyserver.ubuntu.com:80 C58C1F62
gpg: sending key C58C1F62 to keyserver.ubuntu.com:80
gpgkeys: no keyserver host provided
gpg: keyserver internal error
gpg: keyserver send failed: keyserver error

что означает, что сервер существует ? Но раздел вопроса выглядит пустым…
