Description Petr Pisar 2019-11-08 08:01:58 UTC

After upgrading libsolv from 0.7.4-3.el8 to 0.7.7-1.el8, "dnf builddep" on a spec file with a build-require on perl-generators fails like this:

# dnf builddep ~test/rhel/perl/perl.spec 
Last metadata expiration check: 0:04:26 ago on Fri 08 Nov 2019 08:49:28 AM CET.
[...]
Package perl-4:5.26.3-416.el8.x86_64 is already installed.
Package perl-generators-1.10-9.el8.noarch is already installed.
[...]
Error: 
 Problem 1: cannot install the best candidate for the job
  - package perl-4:5.30.0-446.module+el8.2.0+4253+0855625b.x86_64 is excluded
 Problem 2: cannot install the best candidate for the job
  - package perl-generators-1.11-4.module+el8.2.0+4253+0855625b.noarch is excluded
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

But the offending packages belong to perl:5.24 stream that's not enabled:

# dnf module list --enabled perl
Last metadata expiration check: 0:06:48 ago on Fri 08 Nov 2019 08:49:28 AM CET.
Error: No matching Modules to list

This looks like a regression similar to bug #1677583. I have installed:

# rpm -q dnf dnf-plugins-core libdnf librepo libsolv
dnf-4.2.11-1.el8.noarch
dnf-plugins-core-4.0.10-1.el8.noarch
libdnf-0.35.5-1.el8.x86_64
librepo-1.10.6-1.el8.x86_64
libsolv-0.7.7-1.el8.x86_64
