Importing GPG keys from Ubuntu’s KeyServer, a common issue is that your command line terminal may not create the necessary directories. Run this to create these directories.

sudo gpg --list-keys

What you should see:

gpg: directory '/root/.gnupg' created
gpg: keybox '/root/.gnupg/pubring.kbx' created
gpg: /root/.gnupg/trustdb.gpg: trustdb created

The next task is to import the GPG key needed.

sudo gpg --no-default-keyring --keyring /usr/share/keyrings/ondrej.gpg --keyserver keyserver.ubuntu.com --recv-keys 14AA40EC0831756756D7F66C4F4EA0AAE5267A6C

Example output:

gpg: keybox '/usr/share/keyrings/ondrej.gpg' created
gpg: key 4F4EA0AAE5267A6C: public key "Launchpad PPA for Ondřej Surý" imported
gpg: Total number processed: 1
gpg:               imported: 1
