GitHub user zap51 created a discussion: Failure in upgrading CloudStack from
4.19.3.0 to 4.20.2.0
Hi Community,
We upgraded our setup with Ubuntu 20.04 LTS on management and agents to
v4.20.2.0 but it is failing at this stage mentioned below.
We see these in the log file `management-server.out` after starting
`cloudstack-management.service`. The service `cloudstack-management.service`
keeps running but these failures are seen
```sh
WARNING: sun.reflect.Reflection.getCallerClass is not supported. This will
impact performance.
