Plugin won't update (to 3.3.1)


First off, Please accept my apologies for cross posting this on github and here, I don’t know what is the right place to bring up such issues, It can be that there is something wrong with my configuration so any help will be highly appreciated,

I can’t seem to be able to update the login plugin for some reason. it shows updated successfully with the error that it was unable to rmdir because directory isn’t empty.

all the files in the entire directory are chown’d to www-data so I don’t really have a clue if it is a permissions issue or something to do with the update.

I’m sorry for a noob question, I’m very new to the grav universe.
