Aha, inside the docker I can see

[root@26afd7f0f17d linux]# cd /var/spool/cron/
[root@26afd7f0f17d cron]# 
[root@26afd7f0f17d cron]# 
[root@26afd7f0f17d cron]# ls

which seems to be a result of your changes (cron job)

today's java version is

[root@26afd7f0f17d cron]# java --version
openjdk 11.0.22 2024-01-16 LTS
OpenJDK Runtime Environment (Red_Hat-11.0.22.0.7-1) (build 11.0.22+7-LTS)
OpenJDK 64-Bit Server VM (Red_Hat-11.0.22.0.7-1) (build 11.0.22+7-LTS, mixed mode, sharing)

I am still confused about: Whilst being inside the docker, how do I activate the omero-server venv to be able to run cmds like omero admin diagnostics ?

[jburel]

in the docker container, you will see under /home/omero/workspace/OMERO-server a virtual environment .venv3,
activate that virtual environment then you can access the omero commands
