* Solution *
I found the cause: The directory apps/files_rightclick/ contained another directory named files_rightclick once again.
I was able to resolve the problem by hand in three steps.

1. cp -r apps/files_rightclick/files_rightclick/* apps/files_rightclick/
2. sudo -u http ./occ upgrade
3. In config/config.php set maintenance to false

Had the same issue. Solution worked for me also

Same issue with upgrade to 17.0.1. Same fix also worked. Thank you.

same issue upon upgrade but the cp -r solution did not work for me.

The following did work though:

1. mv apps/files_rightclick/ /some/other/place/
2. sudo -u http ./occ upgrade
3. sudo -u http ./occ maintenance:mode --off
