Description Michael Young 2019-01-13 09:43:15 UTC
If /etc/dnf/dnf.conf contains the setting best=1 then dnf builddep will fail
for a package
BuildRequires:	perl-generators
will fail with the error
 Problem: cannot install the best candidate for the job
  - package perl-generators-1.10-7.el8+1703+3db27f7b.noarch is excluded
rather than installing the perl-generators (assuming there aren't any other dependency issues).
This was happening when testing a mock rebuild of cyrus-imapd-3.0.7-15.el8.src.rpm but I reproduced it with a dummy package built from the spec file below to avoid dependency issues.

Name:		testpkg
Version:	0
Release:	1%{?dist}
Summary:	Test Package
License:	BSD
Source0:	test.txt

BuildRequires:	perl-generators


%setup -q

make %{?_smp_mflags}

I forgot to mention that I can't reproduce this in Fedora 29 so it looks like it has been fixed there.

Comment 2 Jaroslav Mracek 2019-01-14 12:27:41 UTC
Please can you provide a version of dnf, libdnf?

Please can you confirm that the issue is reproducible with dnf-4.0.9?

Comment 3 Michael Young 2019-01-14 12:45:54 UTC
The problem is for the RHEL8 public beta rhel-8.0-beta-1 so
which I believe are the latest publicly available versions.
I was not able to reproduce it on Fedora 29 which has
so the bug may well be fixed if there are later private RHEL8 builds of these packages.

Comment 4 Jaroslav Mracek 2019-02-18 21:58:33 UTC
The problem is valid. DNF selector using provide= ignores exclude. The issue cannot be easily fixed, but we have to.
