    This error was resolved in Centos 7.9 after adding the below variables to /etc/environment and logoff/logon as root. Reboot was not needed.

    $ cat /etc/environment
LANG=en_US.utf8
LC_ALL=en_US.utf8

    See more discussion in https://github.com/canonical/microk8s/issues/3760

    This seems to be because the locale C.UTF-8, which is set as a default in so many places, does not exist. A workaround would be to actually generate it:

    localedef -v -c -i POSIX -f UTF-8 C.UTF-8
