with mock-1.1.30-1.fc18.noarch I am running this command: mock -v --target=arm -r fedora-18-arm init But it fails. armhfp works fine. I can't figure out what is possibly going wrong. Log below. Thanks, Adam ERROR: Command failed: # ['/usr/bin/yum', '--installroot', '/var/lib/mock/fedora-18-arm/root/', 'groupinstall', 'buildsys-build'] Error: Package: redhat-rpm-config-9.1.0-37.fc18.noarch (fedora) Requires: /bin/sh Error: Package: redhat-rpm-config-9.1.0-37.fc18.noarch (fedora) Requires: perl(Getopt::Long) Error: Package: redhat-rpm-config-9.1.0-37.fc18.noarch (fedora) Requires: zip Error: Package: redhat-rpm-config-9.1.0-37.fc18.noarch (fedora) Requires: dwz >= 0.4 Error: Package: redhat-rpm-config-9.1.0-37.fc18.noarch (fedora) Requires: /usr/bin/perl Error: Package: redhat-rpm-config-9.1.0-37.fc18.noarch (fedora) Requires: coreutils Error: Package: redhat-rpm-config-9.1.0-37.fc18.noarch (fedora) Requires: /bin/bash Error: Package: redhat-rpm-config-9.1.0-37.fc18.noarch (fedora) Requires: rpm >= 4.8.0 You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest
