I chose Severity S2, since I cannot update to MySQL 8.0.

Hi! Try this workaround (as you should be able to install the required package without installing MySQL 8.0 *server*): $ rpm -Uvh http://repo.mysql.com/yum/mysql-8.0-community/el/7/x86_64/mysql-community-client-plugins-8... and then run $ yum update

Hello Terje, thank you for the fast response. Unfortunately, your suggestion does not seem to work. I fails with the following error: # rpm -Uvh http://repo.mysql.com/yum/mysql-8.0-community/el/7/x86_64/mysql-community-client-plugins-8... Retrieving http://repo.mysql.com/yum/mysql-8.0-community/el/7/x86_64/mysql-community-client-plugins-8... error: Failed dependencies: mysql-community-server < 8.0.21 conflicts with mysql-community-client-plugins-8.0.22-1.el7.x86_64 mysql-community-client < 8.0.22 conflicts with mysql-community-client-plugins-8.0.22-1.el7.x86_64 Do you have any other suggestion? Thank you! Rüdiger

Hi again, try this instead (-Uvh will remove the 5.7 version of the package, however rpm supports install of same package in different versions, if told to): $ rpm -ivh http://repo.mysql.com/yum/mysql-8.0-community/el/7/x86_64/mysql-community-client-plugins-8...

Hello again, does unfortunately still not work: # rpm -ivh http://repo.mysql.com/yum/mysql-8.0-community/el/7/x86_64/mysql-community-client-plugins-8... Retrieving http://repo.mysql.com/yum/mysql-8.0-community/el/7/x86_64/mysql-community-client-plugins-8... error: Failed dependencies: mysql-community-server < 8.0.21 conflicts with mysql-community-client-plugins-8.0.22-1.el7.x86_64 mysql-community-client < 8.0.22 conflicts with mysql-community-client-plugins-8.0.22-1.el7.x86_64 I also tried with --nodeps (do not verify package dependencies), but get the following: # rpm -ivh --nodeps http://repo.mysql.com/yum/mysql-8.0-community/el/7/x86_64/mysql-community-client-plugins-8... Retrieving http://repo.mysql.com/yum/mysql-8.0-community/el/7/x86_64/mysql-community-client-plugins-8... Preparing... ################################# [100%] file /usr/lib64/mysql/plugin/authentication_ldap_sasl_client.so from install of mysql-community-client-plugins-8.0.22-1.el7.x86_64 conflicts with file from package mysql-community-server-5.7.32-1.el7.x86_64 Looks like the dependencies are conflicting for since the latest Connector / Python version between 8.0 and 5.7. Any more suggestion? (Thank you for your help so far)

Hi! You are right, mixing plugins for 5.7 and 8.0 is simply not possible at the moment. So the only viable workaround now is to --nodeps install the connector package itself, it will work just fine, however the feature set found in the plugin will be missing (that's new in 8.0.22 any way).

Hello Terje, thank you. This was the important information to know: "... it will work just fine..." I could update now with: # rpm -Uvh https://dev.mysql.com/get/Downloads/Connector-Python/mysql-connector-python-8.0.22-1.el7.x... --nodeps Retrieving https://dev.mysql.com/get/Downloads/Connector-Python/mysql-connector-python-8.0.22-1.el7.x... Preparing... ################################# [100%] Updating / installing... 1:mysql-connector-python-8.0.22-1.e################################# [ 33%] Cleaning up / removing... 2:mysql-connector-python-cext-8.0.2################################# [ 67%] 3:mysql-connector-python-8.0.21-1.e################################# [100%] And yum update is now happy :) (Will observe a bit on the current server, before I apply the fix to production and other servers). Thank you very much!

Posted by developer: This 8.0.23 release note is suggested by the documentation team: Removed the MySQL client-plugins dependency, although it's recommended. This plugin allows MySQL to use its newer authentication methods, thus it's required for connecting to accounts using the new authentication methods such as caching_sha2_password. Additionally, the C/Py installation documentation also now mentions the client-plugins package as required to use newer authentication methods, such as caching_sha2_password that is the default auth method in MySQL 8.0.
