Answer 1

it worked for me

apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 34893610CEAA9512

you can use script

#!/bin/bash

declare -a keyservers=(
    "hkp://keyserver.ubuntu.com:80"
    "keyserver.ubuntu.com"
    "ha.pool.sks-keyservers.net"
    "hkp://ha.pool.sks-keyservers.net:80"
    "p80.pool.sks-keyservers.net"
    "hkp://p80.pool.sks-keyservers.net:80"
    "pgp.mit.edu"
    "hkp://pgp.mit.edu:80"
)

keys=$(apt update 2>&1 | grep -o '[0-9A-Z]\{16\}$')

for key in $keys; do
    for server in "${keyservers[@]}"; do
        echo "Fetching GPG key ${key} from ${server}"
        apt-key adv --keyserver $server --keyserver-options timeout=10 --recv-keys ${key}
        if [ $? -eq 0 ]; then
            echo "Key '${key}' successful added from server '${server}'"
            break
        else
            echo "Failed add key '${key}' from server '${server}'. Try another server"
            continue
        fi
    done
done

Answer 2

just disconnect your wifi and then again connect. It worked for me.

Answer 3

Looks like you have network access issue or environment issue. This command works fine for me. GPG and Ubuntu versions, which I'm using:

gpg --version | head -2; lsb_release -d
gpg (GnuPG) 2.2.19
libgcrypt 1.8.5
Description:    Ubuntu 20.04.3 LTS

Try to access keyserver.ubuntu.com via curl and see what happens

curl http://keyserver.ubuntu.com | & grep description
      <meta name="description" content="OpenPGP Keyserver">
