YUM displays conflicting requests with modules after installing perl-DBI or perl-DBD-* as shown below.
Problem 1: conflicting requests
- nothing provides module(perl:5.26) needed by module perl-DBD-MySQL:4.046:8010020190322121447:073fa5fe-0.x86_64
Problem 2: conflicting requests
- nothing provides module(perl:5.26) needed by module perl-DBD-SQLite:1.58:8010020190322125518:073fa5fe-0.x86_64
Problem 3: conflicting requests
- nothing provides module(perl:5.26) needed by module perl-DBI:1.641:8010020190322130042:16b3ab4d-0.x86_64
It is impossible to install or enable any other perl stream to enable perl: Module 5.26. Enable perl as follows:
# yum module enable perl:5.26
When the module is activated, the following is displayed:
# yum module enable perl-DBI --assumeno Dependencies resolved. ============================================================================================================================== Package Architecture Version Repository Size ============================================================================================================================== Enabling module streams: perl 5.26 perl-DBI 1.641 Transaction Summary ============================================================================================================================== Operation aborted.
However, when you install content out of the module, you do not get the “perl:5.26” module enabled.
# yum install perl-DBI Dependencies resolved. ============================================================================================================================== Package Arch Version Repository Size ============================================================================================================================== Installing: perl-DBI x86_64 1.641-3.module+el8.1.0+2928+fafc4afc centos-8-for-x86_64-appstream-rpms 740 k Installing dependencies: <snip> Enabling module streams: perl-DBI 1.641 Transaction Summary ============================================================================================================================== Install 44 Packages Total download size: 13 M Installed size: 38 M Is this ok [y/N]: n Operation aborted.
If the above is allowed, the following operations will have unmet modular dependencies, as shown by the.
