Hi

I assume you followed https://docs.moodle.org/39/en/Step-by-step_Installation_Guide_for_Ubuntu. You say, you passed 8.8 and when you come to registering the site at Moodle stats you get this error? Did you try skipping the registration? There is a tiny button for Continue.

In any case try to get a more detailed debug trace by activating https://docs.moodle.org/39/en/Debugging to maximum level, called DEVELOPER.

Thank you very much for your kind reply.

Yes, I followed the same document and exactly stuck at 8.8.

There is no skipping option for registration.

IS there any right steps to solve it?
Please need your kind support and suggestion.

Thank you

In that screen-shot you are at 8.6 https://docs.moodle.org/39/en/Step-by-step_Installation_Guide_for_Ubuntu#Create_a_Site_Administrator_Account.

So when you click on Update profile, it accepts the settings for the administrator and move on to 8.7 Registration. Do you see the long web form with registration details? Pl. attache a screen-shot.

Once your click on Register button on that page, Moodle throws the database error? The way forward is the debugging I explained in my previous post.
