You still haven't shown us the actual error message, so we're all just guessing. I will offer a guess though. This *should* work, since Rocky 9 is a direct descendant of RHEL/CentOS 7. The only reason I can think why it wouldn't is that you haven't installed the OS package that defines en_US.UTF-8. Try doing "locale -a" and see if en_US.UTF-8 is among the listed locales. On my RHEL8 box, it looks like glibc-locale-source is what provides most non-C locales. regards, tom lane
