 Description   

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

# dnf  -y  update ;
 
Last metadata expiration check: 0:04:17 ago on Tue 18 Aug 2020 02:03:54 PM EDT.
 
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

(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

This was first reported here:

https://mariadb.com/kb/en/odd-mariadb-connector-c-error-on-update/

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.

we have the same issue with 10.4:

# dnf -y install MariaDB-devel ;
Last metadata expiration check: 0:02:17 ago on Wed 19 Aug 2020 03:30:45 PM UTC.
All matches were filtered out by modular filtering for argument: MariaDB-devel
* Maybe you meant: mariadb-devel ;
Error: Unable to find a match: MariaDB-devel

# dnf -y install mariadb-devel

EDIT: same issue with 10.3...? 10.3 was first released on 2017-04-16 - i get the feeling that mariadb-connector-c is not maintained anymore?

Hi edwardsmarkf,

I had to work around the problem like this:

1.) Check installed packages:

$ sudo rpm -qa | grep -i mariadb
 
mariadb-connector-c-devel-3.0.7-1.el8.x86_64
 
mariadb-connector-c-3.0.7-1.el8.x86_64
 
mariadb-connector-c-config-3.0.7-1.el8.noarch

2.) Try to install the MariaDB Connector/C packages from MariaDB's repo, and it fails:

$ sudo yum install MariaDB-shared MariaDB-devel
 
Last metadata expiration check: 0:13:18 ago on Wed 19 Aug 2020 07:06:45 PM UTC.
 
Error:

  - conflicting requests
 
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

3.) Remove the 3 mariadb-connector-c* packages from the standard RHEL/CentOS 8 repo:

$ sudo yum remove mariadb-connector-c mariadb-connector-c-config mariadb-connector-c-devel

4.) Try again to install the MariaDB Connector/C packages from MariaDB's repo, and it succeeds this time:

$ sudo yum install MariaDB-shared MariaDB-devel

    UTC.
    All matches were filtered out by modular filtering for argument:

Hi edwardsmarkf,

That's odd. I don't know why that error would occur for you, but it wouldn't occur for me. Did you recently configure your MariaDB repository, or has it been configured for a while? If your repository configuration is too old, then I wonder if you could be hitting MDEV-20673, which was fixed by changing our mariadb_repo_setup script a while ago.

If that is your problem, then it may help to run the mariadb_repo_setup script to reconfigure your repository, as explained here: https://mariadb.com/kb/en/mariadb-package-repository-setup-and-usage/

e.g.:

curl -LsS https://downloads.mariadb.com/MariaDB/mariadb_repo_setup |
 
    sudo bash -s -- --mariadb-server-version="mariadb-10.5"

the issue is confirmed on RHEL-8.

installed packages:

mariadb-connector-c-3.1.11-2.el8_3.x86_64
 
mariadb-connector-c-config-3.1.11-2.el8_3.noarch
 
mariadb-connector-c-devel-3.1.11-2.el8_3.x86_64

the following is errored as per description:

# yum install MariaDB-shared MariaDB-devel
 
Error:
 
 Problem: problem with installed package mariadb-connector-c-devel-3.1.11-2.el8_3.x86_64

  - package mariadb-connector-c-devel-3.1.11-2.el8_3.x86_64 conflicts with mysql-devel provided by MariaDB-devel-10.5.12-1.el8.x86_64

  - cannot install the best candidate for the job

the best way is to set alternative name for devel package, to do not create more provides:

ALTERNATIVE_NAME("devel" "mariadb-connector-c-devel" ${MARIADB_CONNECTOR_C_VERSION}-1)
