I followed the instructions from here.
Open Data Cube core, version 1.8.6
Ubuntu 16.04
SQLAlchemy 1.4.27
After installation tried initialisation of database:
$ datacube -v system init
This command is getting failed with following error:

The above exception was the direct cause of the following exception:

[SQL:

Some issues at github had the same problem but were moreover solved by downgrading SQLAlchemy to 1.2 but not in my case.
