I've got v20.1 pro installed with just the Arria 10 devices. As a test I ran the NCO IP with just the defaults.
These are messages from the Platform Designer generation :
Error: nco_ii_0: Problem getting the aliases for all known families com.altera.infrastructure.devices.DeviceDBException: Could not execute query: SELECT fam_alias.alias, fam.display_name FROM family_alias fam_alias JOIN family fam ON fam.id == fam_alias.family_id union all select name, display_name from family union all select display_name, display_name from family; com.altera.jdbcsqlite.Exception: no such table: family
In your Ubuntu, can you install all device and see the result?
Please note that we are aware of this issue. But we want to collect whether Linux able to resolve it will all device install.
Understand that Windows still failed even though all device had been install.
The temporally workaround provided by the engineering would be the generate the IP in 19.4 and use the RTL generated in the 20.1 Quartus release. We will file a KDB/Documentation on this.
We are sorry for the inconvenience cause,
