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 with MariaDB v10.3.

Any help would be appreciated.

@zap51 , that constraint has been in since 4.0 and is only dropped for 4.20. Can you restore your old DB and check if it is there?

Maybe you can also do a clean 4.19 installation and compare the DB schema to yours to see the differences.
