I'm executing this command: sudo add-apt-repository ppa:ubuntu-toolchain-r/test
And I'm getting this output in terminal:
gpg: keybox '/tmp/tmphrotribt/pubring.gpg' created
gpg: /tmp/tmphrotribt/trustdb.gpg: trustdb created
gpg: key 1E9377A2BA9EF27F: public key "Launchpad Toolchain builds" imported
gpg: Total number processed: 1
gpg: imported: 1
gpg: no valid OpenPGP data found.
Is the command executed well? Or the last line of output "gpg: no valid OpenPGP data found." is some error?
