If you see messages like this:
Click will abort further execution because Python 3 was configured to use ASCII as encoding for the environment. Either run this under Python 2 or consult http://click.pocoo.org/python3/ for mitigation steps. This system lists a couple of UTF-8 supporting locales that you can pick from. The following suitable locales where discovered: aa_DJ.utf8, aa_ER.utf8, aa_ET.utf8, ...
You are likely running Curator with Python 3, or the RPM/DEB package, which was
compiled with Python 3. Using the command-line library
click with Python 3 requires your locale to be Unicode.
You can set this up by exporting the
LC_ALL environment variable like this:
$ export LC_ALL=mylocale.utf8
mylocale.utf8 is one of the listed "suitable locales."
You can also set the locale on the command-line before the Curator command:
$ LC_ALL=mylocale.utf8 curator [ARGS] ...
If you use
export, be sure to choose the correct locale as it will
be set for the duration of your terminal session.
