Could you please actually provide error message from you apt upgrade commands? > **Expected Behavior:** > Once `en_US.UTF-8` is generated and configured, subsystems should uniformly > use it, with no fallback warnings or temporary use of `C.UTF-8`. I am not able to reproduce this issue, the expected behavior is the one I observe here. > **Actual Behavior:** > Early in the boot, glibc (or subsystems) temporarily fall back to `C.UTF-8`, > causing warnings even though the correct locale is already configured. Could you also please provide the error message that you are seeing during boot? > When connecting to the host via SSH: > -bash: warning: setlocale: LC_CTYPE: cannot change locale (UTF-8): No such > file or directory This error message doesn't correspond what you describe. It seems that LC_CTYPE (or LC_ALL) is set to UTF-8, not en_US.UTF-8. Are you sure your ssh client is asking for the en_US.UTF-8 locale?
