Base : SQL Status: HY000

Hello,

I have just installed Libreoffice 5.1.5.2

I am on Mac OSX 10.11.6, Java Version 8 Update 101

I can open my base but when I try to open a form I get the following error :

SQL Status: HY000

The connection to the external data source could not be established. No SDBC driver was found for the URL ‘sdbc:embedded:hsqldb’.

In my case I have java installed and also marked in Tools > Options > Advanced.
Since I did the minimal install for ubuntu, I guess something might have missed there

open terminal and run sudo apt install libreoffice-sdbc-hsqldb. And then it worked for me

I think the answer is in this thread:

Thank you !
