1) Per:

https://www.postgresql.org/docs/16/app-initdb.html

lc_lang does not exist and I get:

/usr/lib/postgresql/16/bin/initdb: unrecognized option '--lc-lang=en_US'

2) On Ubuntu 22.04 doing:

/usr/lib/postgresql/16/bin/initdb -D postgres/16/data/ -E 'UTF-8'
--lc-collate='en_US.utf8' --lc-ctype='en_US.utf8'

I get:

postgres=# \l

3) What does locale -a return on your machine?
