When yum installed local packages, it defaulted to expecting SHA-256 checksums. Because packages for Red Hat Enterprise Linux 5 use MD5 checksums, the installation would fail with a bad checksum type error. Now, when yum encounters a bad SHA-256 checksum, it attempts to verify the package with a SHA-1 checksum instead, which will sucessfully verify the MD5 checksums used for Red Hat Enterprise Linux 5 packages.

Is rhel5 supporting sha256 checksums?
Comment 3 Petr Sklenar 2009-05-13 14:22:44 EDT
How could I find it?
Comment 4 seth vidal 2009-05-13 14:36:06 EDT
okay, I need some info: 1. can you provide a link to the repodata where these pkgs came from? 2. can you provide the set of pkgs installed on the system(s) where you were running this? thanks

I'm also reming the Regression keyword, until we get more info. ... as I _highly_ doubt that this is true (that it works on 5.3, that is).

Comment 7 Petr Sklenar 2009-05-13 15:33:36 EDT
system points to rhn.webqa.redhat.com and packages are downloading from channel "rhn satellite" you can try it on rhts machine: amd-toonie2-01.rhts.bos.redhat.com folder: /mnt/hostel/local/Satellite-5.3.0-RHEL5-re20090507.1-i386 ./install.pl then see log with yum: tail -f /var/log/rhn/rhn-installation.log
Comment 8 James Antill 2009-05-13 16:16:30 EDT
Ok, I lied ... it's localinstall defaulting to sha256. This patch fixes it: diff --git a/yum/packages.py b/yum/packages.py index 3dc7a15..48cee27 100644 --- a/yum/packages.py +++ b/yum/packages.py @@ -1580,7 +1580,9 @@ class YumLocalPackage(YumHeaderPackage): def localPkg(self): return self.localpath - def _do_checksum(self, checksum_type='sha256'): + def _do_checksum(self, checksum_type=None): + if checksum_type is None: + checksum_type = misc._default_checksums if not self._checksum: self._checksum = misc.checksum(checksum_type, self.localpath) self._checksums = [(checksum_type, self._checksum, 1)]

Release note added. If any revisions are required, please set the "requires_release_notes" flag to "?" and edit the "Release Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: When yum installed local packages, it defaulted to expecting SHA-256 checksums.
