Description Jim Goddard 2011-08-26 19:00:38 UTC

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

This issue is more accurately attached to the mock package, and as such this can/should be closed, unless it turns out to be an issue with yum after all, which is unlikely.

Comment 2 James Antill 2011-08-26 22:02:08 UTC

 As the message says, the problem is that the rpms you are operating with use features that aren't available in the version of rpm that ships with RHEL-5 (sha256 checksums and xz compression).
 You will have similar problems with the yum code needing python-hashlib to access RHEL-6 repos.
