Official documentation

Method 2 Import via GnuPG

Fetches the key from a public keyserver and imports it into the RPM trust store.

openSUSE — bash
$ gpg --keyserver hkps://keys.openpgp.org --recv-keys EB3E94ADBE1229CF
$ gpg --export --armor EB3E94ADBE1229CF | sudo rpm --import -
$ sudo zypper refresh

After importing the key

Run sudo apt-get update (or your distro's equivalent) again. If successful you should see Hit: lines with no EXPKEYSIG warnings. Still broken? Check that your /etc/apt/sources.list.d/ entry references the correct [signed-by=…] keyring path.
