I tried with the URL access localhost:8080/mw-config/ but when I get to the step 'Upgrade existing installation' i got this error

An error occurred:

Error 1091: Can't DROP INDEX `user_timestamp`; check that it exists

Function: Wikimedia\Rdbms\Database::sourceFile( /var/www/html/maintenance/archives/patch-revision-actor-comment-MCR.sql )

I found a solution to my answer. I commented out the files executing the blocking commands to my version upgrade. Then I reassembled them on my container.

patch-archive-MCR.sql & patch-revision-actor-comment-MCR
