When running @apexins.sql on freshly created PDB I see error:

Timing command is obsolete.

This is stopping the whole installation for me (on DB 19c)
Looks like it is caused by core/tab.sql alter table (line 16512):
alter table wwv_flow_task_def_actions add constraint wwv_task_def_act_uk unique (task_def_id, name) using index compress 2
