Description Jon W 2020-04-08 18:31:07 UTC

Description of problem:
I am trying install RT4 on RHEL 8.1, which requires perl-XML-RSS, and it fails to find a perl(DateTime::Format::Mail) provider. The perl module was through CPAN, and it still fails.

You can find the perl-DateTime-Format-Mail rpm in the Powertools repository.
EPEL depends on that repository being enabled.

https://fedoraproject.org/wiki/EPEL#Quickstart

> The perl module was through CPAN, and it still fails. 

Installing from CPAN does not update the rpm database. Hence, the requirement is still not satisfied (from rpm's point of view) and the installation still fails.

Comment 2 Jon W 2020-04-08 18:54:58 UTC

Where does that repo come from? I cannot enable it on RHEL 8. This returns when trying to enable it: Error: No matching repo to modify: PowerTools.

Red Hat CodeReady Linux Builder for RHEL 8 x86_64 is enabled, though.

Comment 3 Emmanuel Seyman 2020-04-08 22:05:45 UTC

In CentOS, it's defined in /etc/yum.repos.d/CentOS-PowerTools.repo which is provided by the centos-repos package. I've no idea what provides it in RHEL.

Comment 4 Paul Howarth 2020-04-09 08:57:50 UTC

It (perl-DateTime-Format-Mail-0.403-6.el8) should be in codeready-builder-for-rhel-8-x86_64-rpms according to the list in Fedora Infrastructure:

https://infrastructure.fedoraproject.org/repo/json/pkg_el8.json

Comment 5 Paul Howarth 2020-04-09 09:13:17 UTC

Can you try downloading the perl-DateTime-Format-Mail rpm and check that it actually provide 'perl(DateTime::Format::Mail)'? The one in CentOS does so I'd be surprised if it didn't.

dnf download perl-DateTime-Format-Mail
rpm -qp --provides perl-DateTime-Format-Mail*.rpm

Comment 6 Jon W 2020-04-09 13:29:37 UTC

Thanks, Paul, that did the trick. I didn't sync the repo after adding the subscription in Satellite. I'm guessing that's why I wasn't able to find that RPM.
