addrepo doesn't work with ubuntu 18.04 x86_64

[Bruno Cornec]

using an addrepo entry for a project doesn't work for an Ubuntu 18.04 x86_64 container.

pb_distro_setuprepo_gen doesn't seem to be called as no trace of the message from it when invoked with debug

1st problem the conf file was incorrect.

2/ we then still have an issue:

W: GPG error: ftp://ftp.project-builder.org//ubuntu 18.04 Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 6BA8C2D220EBFB0E
E: The repository 'ftp://ftp.project-builder.org//ubuntu 18.04 Release' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

Normally handled in #155 Seems that the gpg --verify answer is different for Ubuntu 18.04 (no ID keyword after the key keyword) In which case the GPG key cannot be found and added to the apt keyring.
