Failed: ALTER TABLE {acidfree} ADD COLUMN share TINYINT(1) NOT NULL DEFAULT '0'

I am getting this fail on update #2 after upgrading from drupal 4.7 to 5.16. On another site I also took from 4.7 to 5.16 everything went well , but this site shows no user albums and the root album is showing empty.
Duplicate column name 'share' query: ALTER TABLE acidfree ADD COLUMN share TINYINT(1) NOT NULL DEFAULT '0'
All other steps seem fine -

ALTER TABLE {acidfree} DEFAULT CHARACTER SET utf8
ALTER TABLE {acidfree} CHANGE `class` `class` varbinary(16) DEFAULT '' NOT NULL, CHANGE `large` `large` varbinary(255) DEFAULT '' NOT NULL, CHANGE `small` `small` varbinary(255) DEFAULT '' NOT NULL, CHANGE `thumb` `thumb` varbinary(255) DEFAULT '' NOT NULL
