What version are you upgrading from?

It is running a query from the 2.0 upgrade suggesting you have 2.0 but in reality maybe you have 2.0.0

Try running this query in phpmyadmin and tell me if you run upgrade again your problems are solved.

UPDATE vb3_adv_setting SET value = '2.0.0' WHERE varname = 'gallery_version';
