Description of problem: Attempting to use Mock Version: 1.0.19 on CentOS 5.6 (cr) to build an el6 version of rsyslog-5.8.4 the yum install of the chroot environment fails with a dependency check: ERROR: Command failed: # ['/usr/bin/yum', '--installroot', '/var/lib/mock/epel-6-x86_64/root/', 'groupinstall', 'buildsys-build' <snip> ERROR with rpm_check_debug vs depsolve: rpmlib(FileDigests) is needed by elfutils-0.148-1.el6.x86_64 rpmlib(PayloadIsXz) is needed by elfutils-0.148-1.el6.x86_64 rpmlib(FileDigests) is needed by hwdata-0.233-1.el6.noarch rpmlib(PayloadIsXz) is needed by hwdata-0.233-1.el6.noarch <snip> Doesn't matter if I pick i386 or x86_64 configs, I get the same error. Same server builds el5 packages just fine using mock. Similarly a CentOS6 x86_64 box can successfully build el6 & el5 packages for either arch. CentOS6 box is running Mock Version 1.1.12 Version-Release number of selected component (if applicable): Mock Version: 1.0.19 How reproducible: every time Steps to Reproduce: 1. download or build srpm 2. mock -r epel-6-i386 --rebuild ~/rpm/SRPMS/rsyslog-5.8.4.src.rpm 3. error occurs Actual results: ERROR: Command failed: # ['/usr/bin/yum', '--installroot', '/var/lib/mock/epel-6-x86_64/root/', 'groupinstall', 'buildsys-build' <snip> ERROR with rpm_check_debug vs depsolve: rpmlib(FileDigests) is needed by elfutils-0.148-1.el6.x86_64 rpmlib(PayloadIsXz) is needed by elfutils-0.148-1.el6.x86_64 rpmlib(FileDigests) is needed by hwdata-0.233-1.el6.noarch rpmlib(PayloadIsXz) is needed by hwdata-0.233-1.el6.noarch Expected results: el6 version of package is built Additional info: Accidentally submitted bug https://bugzilla.redhat.com/show_bug.cgi?id=733768 against yum for this issue.
I think this bug against mock should be closed as invalid / wontfix, because this issue does not relate directly to mock and not something that can be fixed within mock. If you want to build RHEL6 packages on a RHEL5 system, you need to install a patched version of rpm from Fedora Infrastructure repositories that supports XZ payloads and SHA hashes (at least until this functionality is officially implemented in RHEL5, which may or may not happen, open a support request with RH if you think that it's an important issue). See the following bugs for reference: https://bugzilla.redhat.com/show_bug.cgi?id=490613 https://bugzilla.redhat.com/show_bug.cgi?id=620674 Z.

Agreed, this is not something we can address via mock.
