Description tarkan.nein@adorsys.com 2021-05-21 09:32:58 UTC

Description of problem:
Impossible to install perl due to broken dependencies.

How reproducible:
Try to install perl.

Steps to Reproduce:
1. microdnf install perl

Actual results:
error: No available modular metadata for modular package 'perl-libnetcfg-4:5.30.1-451.module+el8.3.0+6961+31ca2e7a.noarch'; cannot be installed on the system

Expected results:
Perl to be installed.

Comment 1 tarkan.nein@adorsys.com 2021-05-21 12:42:53 UTC

A possible workaround is to use module stream version 5:30:

  microdnf module enable perl:5.30

Comment 2 Ben 2021-05-21 16:15:07 UTC

Same issue here as well. I have tried multiple work arounds.

Comment 3 Ben 2021-05-21 16:54:01 UTC

I was able to get around it using your DNF trick and installing perl with dnf instead of yum.

Unfortunately on another project we cant get 5.26 to load anymore and 5.3 is breaking it.

Comment 5 venkata madugundu 2021-05-24 07:25:14 UTC

I am also seeing the same issue while installing perl in a ubi-minimal derived image.

----
FROM registry.access.redhat.com/ubi8/ubi-minimal:latest

RUN microdnf update && microdnf install perl && microdnf clean all
----

I tried to install 5.3 as suggested in one of the comments above and that goes through.

----
FROM registry.access.redhat.com/ubi8/ubi-minimal:latest

RUN microdnf update && microdnf module enable perl:5.30 && microdnf install perl && microdnf clean all
----

Comment 6 Petr Pisar 2021-05-24 08:55:37 UTC

If your package manger reports that modular metadata are missing for perl:5.26 stream,
then the problem is probably in a repository your system is using. To check out what's
wrong with your repository, we need to know which repository (URL) you use.
"dnf repolist -v" should tell you it and you should share with us the URL.

In my experience it's very often caused by a misconfigured Satellite mirror. I.e. not
a bug in Red Hat repository, but in a user's own mirror.

Comment 7 venkata madugundu 2021-05-24 09:49:42 UTC

We are building a container image with the 'registry.access.redhat.com/ubi8/ubi-minimal:latest' base image. And the repolist with 'microdnf repolist' is as follows...

repo id                                                                repo name                                                                              
ubi-8-appstream                                                        Red Hat Universal Base Image 8 (RPMs) - AppStream                                      
ubi-8-baseos                                                           Red Hat Universal Base Image 8 (RPMs) - BaseOS                                         
ubi-8-codeready-builder                                                Red Hat Universal Base Image 8 (RPMs) - CodeReady Builder


The relevant URLs for the above repos per /etc/yum.repos.d/ are...

ubi-8-appstream
	https://cdn-ubi.redhat.com/content/public/ubi/dist/ubi8/8/x86_64/appstream/os

ubi-8-baseos
	https://cdn-ubi.redhat.com/content/public/ubi/dist/ubi8/8/x86_64/baseos/os

ubi-8-codeready-builder
	https://cdn-ubi.redhat.com/content/public/ubi/dist/ubi8/8/x86_64/codeready-builder/os

So looks to me the perl:5.26 metadata is broken in https://cdn-ubi.redhat.com/content/public/ubi/dist/ubi8/8/x86_64/appstream/os/Packages/p/

Comment 8 Petr Pisar 2021-05-24 10:40:04 UTC

Thanks. It seems this repository is missing modular metadata for the previous perl:5.30 module build perl:5.30:8030020200609055348, but it presents its RPM packages. We will forward this bug report to UBI repository maintainers to fix it.

Comment 9 shubh.vashisht@capgroup.com 2021-05-24 21:36:46 UTC

is this issue fixed and pushed?

Comment 10 Jitka Plesnikova 2021-05-25 13:55:06 UTC

Perl team can't solve it. The metadata in UBI repository has to be fixed, the ticket for it was created.

Comment 11 shubh.vashisht@capgroup.com 2021-05-25 16:52:51 UTC

can we please increase the priority of this fix. we are not able to build and release our components.

Comment 12 lanak 2021-05-25 19:37:19 UTC

Please increase priority of this fix, this is a blocking issue for IBM SPP containers team.

Comment 13 Petr Pisar 2021-05-26 07:15:21 UTC

A workaround is masking the offending RPM packages in a package manager by appending this one long line to /etc/dnf/dnf.conf:

Comment 14 michael.bruenker 2021-05-26 13:11:53 UTC

This Bug affects several Images of course and there seem to exist different bugreports already (e.g. https://bugzilla.redhat.com/show_bug.cgi?id=1963153)
We experience this problem in ubi8/openjdk Images and implemented "--nobest" as an option for all our microdnf calls to be able to build again.

Comment 16 Shane Heroux 2021-05-26 16:14:05 UTC

This is a blocking issue for IBM Cloud Pak teams as well, please consider for priority

Comment 17 Petr Pisar 2021-05-27 05:38:46 UTC

A root cause was identified and our release engineering team is fixing a tool which creates UBI repositories to correctly couple modular packages with modular metadata.

Comment 20 Petr Pisar 2021-06-04 10:32:22 UTC

Our release engineering team developed a fix and will regenerate the broken repository. The changes are expected to become visible on our mirrors the next day.

Comment 21 michael.bruenker 2021-06-07 06:04:34 UTC

Unfortunately the fix doesn't seem to work the way it should (from my point of view). While the perl-libs error doesn't come up any longer, there now seems a new sideeffect with rpm-libs:
When trying to update ubi8/openjdk image the following error is thrown:

 Problem: cannot install both rpm-libs-4.14.3-13.el8.x86_64 and rpm-libs-4.14.3-4.el8.x86_64
  - package rpm-plugin-systemd-inhibit-4.14.3-4.el8.x86_64 requires rpm-libs(x86-64) = 4.14.3-4.el8, but none of the providers can be installed
  - cannot install the best update candidate for package rpm-libs-4.14.3-4.el8.x86_64
  - problem with installed package rpm-plugin-systemd-inhibit-4.14.3-4.el8.x86_64

Comment 22 Petr Pisar 2021-06-07 07:37:04 UTC

The modular perl:5.30 issue is resolved now.

That's a different issue. For an unknown reason, UBI8 baseos repository
is missing rpm-plugin-systemd-inhibit-4.14.3-13.el8.x86_64 package while
having rpm-libs-4.14.3-13.el8.x86_64. It actually does not contain any
rpm-plugin-systemd-inhibit package. Maybe it has never contained it.
I have no idea. I recommend you reporting it to Red Hat support
<https://access.redhat.com/support> where you will be helped with triaging
your issue (e.g. there is no "ubi8/openjdk" image
<https://catalog.redhat.com/software/containers/search?q=openjdk>).
