Seeing cannot change locale (en_US.utf-8) because it has an invalid name in slurm_resume.log

This can occur if you have an unsuccessful yum installation process that left the locale settings in an inconsistent state. For example, this can be caused when a user terminates the install process.

To verify the cause, take the following actions:

  • Run su - pcluster-admin.

    The shell shows an error, such as, cannot change locale...no such file or directory.

  • Run localedef --list.

    Returns an empty list or doesn't contain the default locale.

  • Check the last yum command with yum history and yum history info #ID. Does the last ID have Return-Code: Success?

    If the last ID doesn't have Return-Code: Success, the post-install scripts might not have run successfully.

To fix the issue, try rebuilding the locale with yum reinstall glibc-all-langpacks. After the rebuild, su - pcluster-admin doesn't show an error or warning if the issue is fixed.
