So, im no phpBB expert, not at all, please correct me if i'm wrong.
But i just updated my Strato phpBB installation to 3.3, did the manual update and it failed at the user_emoji_permission file, so directly at the beginning of the installation with the "aquiring locks error".
I couldn't find any fixes, so i just hit the update button again, and it failed again.
Then i closed FileZilla (cause i had it open in the background), hit the update Button again and it worked.
I dont know if that could be a solution for some people, but maybe FileZilla is writing stuff in the background, and the update cant overwrite certain files of it.
So try to close your FTP Client before fixing any .php files
