How to Install Osclass on Utuntu 20.4?

Has anyone installed Osclass version 5 on an ubuntu 20.4 server?
I’ve tried following this
with the exception of server names and pulling from GitHub - mindstellar/Osclass: With Osclass, get your own classifieds site for free. Build your own Osc.
Should that work?
Or is there an install guide somewhere someone could point me to.

I’ve got this far. Now its stating that cURL extension is required?
I have installed cURL.
Any suggestions?

got passed that hurdle, found some modules missing for php-curl.

Now when I enter the db user mane and password when I created the db I get this?

Any suggestions?

I’ve tried changing the table prefix.

how did you fix this issue ?
