What were you trying to do that didn't work? Switching perl module stream to 5.32 and updating the system Steps to reproduce Make sure initially perl:5.26  module stream is enabled and install perl-B-Debug package # yum module list perl  Red Hat Enterprise Linux 8 for x86_64 - AppStream (RPMs) Name Stream Profiles Summary perl 5.24 common [d], minimal Practical Extraction and Report Language perl 5.26 [d] common [d], minimal Practical Extraction and Report Language perl 5.30 common [d], minimal Practical Extraction and Report Language perl 5.32 common [d], minimal Practical Extraction and Report Language Hint: [d]efault, [e]nabled, [x]disabled, [i]nstalled # yum install perl-B-Debug Switch perl module stream from 5.26 to 5.32 # yum module reset perl # yum module enable perl:5.32 Try patching the system and it fails with below error # yum update Error: Problem 1: cannot install both perl-libs-4:5.32.1-473.module+el8.10.0+21354+3ad137bb.x86_64 and perl-libs-4:5.26.3-422.el8.x86_64 - package perl-B-Debug-1.26-2.el8.noarch requires perl(:MODULE_COMPAT_5.26.2), but none of the providers can be installed - cannot install the best update candidate for package perl-libs-4:5.26.3-422.el8.x86_64 - cannot install the best update candidate for package perl-B-Debug-1.26-2.el8.noarch - package perl-libs-4:5.26.3-416.el8.x86_64 is filtered out by modular filtering - package perl-libs-4:5.26.3-416.el8.i686 is filtered out by modular filtering - package perl-libs-4:5.26.3-419.el8.x86_64 is filtered out by modular filtering - package perl-libs-4:5.26.3-417.el8_3.i686 is filtered out by modular filtering - package perl-libs-4:5.26.3-419.el8.i686 is filtered out by modular filtering - package perl-libs-4:5.26.3-417.el8_3.x86_64 is filtered out by modular filtering - package perl-libs-4:5.26.3-419.el8_4.1.x86_64 is filtered out by modular filtering - package perl-libs-4:5.26.3-419.el8_4.1.i686 is filtered out by modular filtering - package perl-libs-4:5.26.3-420.el8.x86_64 is filtered out by modular filtering - package perl-libs-4:5.26.3-420.el8.i686 is filtered out by modular filtering - package perl-libs-4:5.26.3-421.el8.i686 is filtered out by modular filtering - package perl-libs-4:5.26.3-421.el8.x86_64 is filtered out by modular filtering - package perl-libs-4:5.26.3-422.el8.i686 is filtered out by modular filtering - package perl-libs-4:5.26.3-422.el8.x86_64 is filtered out by modular filtering Problem 2: problem with installed package perl-B-Debug-1.26-2.el8.noarch - package perl-B-Debug-1.26-2.el8.noarch requires perl(:MODULE_COMPAT_5.26.2), but none of the providers can be installed - cannot install both perl-libs-4:5.32.1-473.module+el8.10.0+21354+3ad137bb.x86_64 and perl-libs-4:5.26.3-422.el8.x86_64 - package perl-Errno-1.30-473.module+el8.10.0+21354+3ad137bb.x86_64 requires perl-libs(x86-64) = 4:5.32.1-473.module+el8.10.0+21354+3ad137bb, but none of the providers can be installed - cannot install the best update candidate for package perl-Errno-1.28-422.el8.x86_64 - package perl-libs-4:5.26.3-416.el8.x86_64 is filtered out by modular filtering - package perl-libs-4:5.26.3-416.el8.i686 is filtered out by modular filtering - package perl-libs-4:5.26.3-419.el8.x86_64 is filtered out by modular filtering - package perl-libs-4:5.26.3-417.el8_3.i686 is filtered out by modular filtering - package perl-libs-4:5.26.3-419.el8.i686 is filtered out by modular filtering - package perl-libs-4:5.26.3-417.el8_3.x86_64 is filtered out by modular filtering - package perl-libs-4:5.26.3-419.el8_4.1.x86_64 is filtered out by modular filtering - package perl-libs-4:5.26.3-419.el8_4.1.i686 is filtered out by modular filtering - package perl-libs-4:5.26.3-420.el8.x86_64 is filtered out by modular filtering - package perl-libs-4:5.26.3-420.el8.i686 is filtered out by modular filtering - package perl-libs-4:5.26.3-421.el8.i686 is filtered out by modular filtering - package perl-libs-4:5.26.3-421.el8.x86_64 is filtered out by modular filtering - package perl-libs-4:5.26.3-422.el8.i686 is filtered out by modular filtering - package perl-libs-4:5.26.3-422.el8.x86_64 is filtered out by modular filtering (try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages) Expected results Patching should complete without any error.
