apt-0.5 uses the \"APT::GPG::Pubring\" parameter to find the pubring file, not the old \"APT::GPG::PubringPath\" which specified only the path to the directory where the file is located. The default apt.conf should be modified accordingly. --- --- apt-0.5-0.5.4cnc7-alt0.1
Fixed in 0.5.4cnc9-alt0.1 Ivan, please resolve bugs you are fixing!
