Tables missing when copy odb from mac to ubuntu?

I created a new database and form in LO Base on an imac.
Copied the odb file to the Ubuntu PC.
When I open the odb on Ubuntu, the tables are missing. The form is present, but cannot be used because the table does not exist.
What went wrong?

Hi @BlackDalek,

  • If you copy the odb back to the iMac, does it work again?
  • Are you using the same version of LO on both machines?

@BlackDalek – update?
