No occ file in var/www/owncloud folder

Hi all

After an update of apache2, i’m not able anymore to log into my owncloud through the web access. I receive an error 404.
I would like to repair owncloud through the occ command but I do not have any occ file in the folder /var/www/owncloud anymore.

Would one of you have an idea how to bring it back by any chance?

Thanks

Looks like the same you have already posted in 404 error after apache update ?

Definitively the same issue. I tried to explain it in a shorter way, hopping to attract more answers as I’m quite desperate.
