Fontconfig problem with one of the fonts

Hi Franek,

just to add to other comments already sent.

This has nothing to do with the TeX Live fonts configuration. From what
is shown there, it looks like a proper fonts.conf file, mine contains
the same data.

So my guess is that the zoom-client snap is just messed up - anyway, the
zoom client snap will have its private fontconfig AFAIR.

> This is only one application but errors are caused by any application which need to be installed or refreshed by snap. If I remove "09-texlive.conf" and re-cache all fonts:
> rm -f ~/.cache/fontconfig/*
> sudo rm -f /var/cache/fontconfig/*
> sudo fc-cache -rv

This is strange, because the above errors don't point to anything
related to TeX Live.

I don't have any experience with snap, but I guess it detects that the
outside world (snap is somehow a sandbox) has a changed fontconfig
configuration, and tries to mimic that - but the snap fontconfig library
is too old to read the config files of the host system.

But this is all only crystal ball reading.

So, to sum it up:
* nothing in the error messages you send has a relation to TeX Live
* I guess that any other change in /etc/fonts/conf.d/ would trigger
  something similar
* the bug is at best in Snap, and not in TeX Live.

Best
