    Description

      The mariadb-connector-c-devel package from the standard RHEL 8 repo conflicts with MariaDB's packages. e.g.:

      # dnf  -y  update ;

      Error:
       Problem: package mariadb-connector-c-devel-3.0.7-1.el8.x86_64 requires mariadb-connector-c = 3.0.7-1.el8, but none of the providers can be installed
        - package MariaDB-shared-10.5.5-1.el8.x86_64 obsoletes mariadb-connector-c provided by mariadb-connector-c-3.0.7-1.el8.x86_64
        - package MariaDB-shared-10.5.5-1.el8.x86_64 obsoletes mariadb-connector-c provided by mariadb-connector-c-3.0.7-1.el8.i686
        - cannot install the best update candidate for package mariadb-connector-c-devel-3.0.7-1.el8.x86_64
        - cannot install the best update candidate for package mariadb-connector-c-3.0.7-1.el8.x86_64
      (try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
      

      This was first reported here:

      As far as I can tell, it looks like the problem is that our MariaDB-devel package should take precedence over the mariadb-connector-c-devel package from the standard RHEL 8 repo, but it currently doesn't.

      We solved a similar problem for the MariaDB-devel package by making mariadb-connector-c an "alternative name" for the MariaDB-devel package:

      ELSEIF(RPM MATCHES "(rhel|centos)8")
      ...
        ALTERNATIVE_NAME("shared" "mariadb-connector-c" ${MARIADB_CONNECTOR_C_VERSION}-1)
        ALTERNATIVE_NAME("shared" "mariadb-connector-c-config" ${MARIADB_CONNECTOR_C_VERSION}-1)
      ...
      ENDIF()
      

      https://github.com/MariaDB/server/blob/mariadb-10.5.5/cmake/cpack_rpm.cmake#L238

      I suspect that we need a similar rule to add mariadb-connector-c-devel as an alternative name for the MariaDB-devel package.
