Hi everyone

Fresh install today on a new computer. I get this error during the install
process and after an attempted update:

loading         > ConTeXt Spacing Macros / Horizontal
resolvers       > lua > loading file
'/home/christian/context/tex/texmf-context/tex/context/base/mkxl/spac-hor.lmt'

The control sequence at the end of the top line of your error message was
never
\def'ed. You can just continue as I'll forget about whatever was undefined.

I can't generate the needed cont-en format file for context to work.

Is that a known problem? Am I missing something? I don't think it is
related to the aarch64 architecture. But who knows...

Thanks for your help!

Kind regards
Christian
