Those of you who’ve tried building RPMs for c5 on a c6 machine might’ve faced the symptoms described in http://samixblog.blogspot.com/2011/11/yum-errno-3-error-performing-checksum.html
The cause seems to involve a couple of things: 1. c6 having adopted a stronger file digest algorithm (sha256 as opposed to md5 in c5) and 2. compressing the payload with xz (as opposed to nothing in c5).
This is easily remedied by passing relevant options to `rpmbuild’ and `createrepo’.
If you’re using fpm in your CI, you can now append the following to your fpm command invocation:
--rpm-rpmbuild-define '_source_filedigest_algorithm md5' \ --rpm-rpmbuild-define '_binary_filedigest_algorithm md5' \ --rpm-rpmbuild-define '_source_payload nil' \ --rpm-rpmbuild-define '_binary_payload nil' \
And invoke createrepo as `createrepo -d -s sha1 –update /path/to/rpms/for/c5′
