Answer 1

Check your eav_attribute_option_value database table & set autoincrement sequencing to next increment number. And then do as what stated by Manish Chaubey.

Remove duplicate primary key entry from table and then do setup upgrade.

Answer 2

Check your table which has duplicate entry and delete one.

Then run command bin/magento setup:upgrade .
