```

I tried to add the key with diff methods, but the same resaults:

```auto
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 2DA21A850F8A3C54
Executing: /tmp/apt-key-gpghome.q22eklS8p7/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys 2DA21A850F8A3C54
gpg: keyserver receive failed: No data

```

```auto
sudo apt-key adv --keyserver hkps://keys.openpgp.org --recv-keys 2DA21A850F8A3C54
Executing: /tmp/apt-key-gpghome.KfdXdJIXbc/gpg.1.sh --keyserver hkps://keys.openpgp.org --recv-keys 2DA21A850F8A3C54
gpg: keyserver receive failed: No data

```

Any idea, what is the problem?
