On my server I installed dokku and created a new App: myNodeApp
$ dokku apps:create myNodeApp
On my local repo I added the dokku remote and want now to push the existing code to my container, after git add . :
$ git push dokku main

This is a Docker issue. Docker v23 accidentally added a hard dependency on AppArmor, and v23.0.1 implemented an incorrect fix, changing the error message to the one you encountered.
For the moment, the fix is one of:
a) Downgrade Docker to below v23
b) Install the apparmor package (I also had to reboot)
c) The issue for the new error has been closed and is marked to go out in v23.0.2.
