The fonts exists only below /usr/share/texmf/fonts/ and
the system fonts below /usr/share/font ... there is no
TL font within the later path.
The problem occurs due XeTeX which seems to depend on
an on fontconfig to be able to handle its fonts below
the TL path, compare with

A simply fc-cache may fix this ...

I've tried to export
FONTCONFIG_FILE, FONTCONFIG_PATH, and FC_CACHEDIR
by using e.g.
export FONTCONFIG_PATH=$(kpsewhich -var-value=FONTCONFIG_PATH)
and this seems to works flawless with xelatex.

Hmmm ... I've several bug reports about fontconfig and XeTeX using
the TL fonts ... one part of reports (the non XeTeX users) are
shouting about the incompatible TL fonts now found due to the
mentioned fontconfig setup at
and other bug report of XeTeX users which insist on exactly this
