Runtime 24.10.000.036 fails with "MySQL/MariaDB is not supported" (Maria 10.11.7 and Python3.11)

[JuergenB]

So,

after the new runtime has been release, Agnitas recommend the new mariaDB version 10.11.7.
With this release Agnitas recommends Python3.11

But with these recommendations, the installaer fails and claims that MariDB is not supported.

Code: Select all

The mandatory database vendor MySQL/MariaDB is not supported by this python installation.
Please install mandatory driver manually

phyton3 is replaced by phyton 3.11 and Agnitas recommend to install with

Code: Select all

python3 -m pip install mariadb==1.0.11 

But python3 has been replaces.

Can you fix the runtime?

This looks more like a packaging or installer issue than MariaDB itself, since 10.11 is supported. Have you tried explicitly installing the mariadb driver with python3.11 -m pip and checking which python binary the installer actually calls?

Hi,
i used the latest 25.04 Admin Guide and was able to setup OpenEMM from scratch with AlmaLinux 9.7 and MariaDB 10.11.7

But now if i upgrade this system to 25.11 i get this error message.

Code: Select all

Checking python installation ...
Python version found: 3.11.13 (/usr/bin/python3.11)
Checking Zip installation ...
Zip version 3.0 found
Starting python ...
The mandatory database vendor MySQL/MariaDB is not supported by this python installation.
Please install mandatory driver manually

MairaDB is version locked.

What are the exact requirements for 25.11 and mariadb?

I searched Environment.py in both releases but was not able to find the culprit.

can you help?
