Yes that this:

  sudo -u postgres /usr/bin/pg_ctlcluster 15 main stop -- -m fast -D 
/var/lib/postgresql/13/main

is not correct.

First do:

pg_lsclusters

to determine what is actually running.

Then do

sudo -u postgres /usr/bin/pg_ctlcluster <version> main stop -- -m fast 
-D /var/lib/postgresql/13/main stop -m fast

for whatever version is running.
