2. Verify your current PMM version: Check your current PMM version by navigating to PMM Configuration > Updates or by running the following command. If accessing remotely, replace localhost with the appropriate IP address or server name:

   podman exec -it pmm-server \
   curl -ku admin:admin https://localhost/v1/version
