http://askubuntu.com – Trying to download Django source package using dget and the .dsc file from here. Then dget fails to verify the source, because it is missing a public key. $ dget https://launchpad.net/ubuntu... [...] dscverify: python-django_1.4.1-2.dsc failed signature check: gpg: Signature made Tue 21 Aug 2012 09:12:04 CEST using RSA key ID F2AC729A gpg: Can't check signature: public key not found Validation FAILED!! Fine, I added this key to my keyring, because I think I can trust this one: $ gpg --keyserver keyserver.ubuntu.com --recv-key 0xF2AC729A gpg: requesting key F2AC729A from hkp server keyserv (HowTos)
