I download
lilypond-2.19.26-1.linux-64.sh
from
http://lilypond.org/development.html
navigate to Desktop (where it is stored) and then:
sh lilypond-2.19.26-1.linux-64.sh

No !!

yes

I uninstalled it and re-installed it, with a fresh download of
lilypond-2.19.26-1.linux-64.sh
(refusing to rename it for now)
exercising  all the steps listed above.

Not sure what exactly you suggest.
I tried to copy/paste conf.avail from 2.18.2 to 2.19.26
The issue persists, though.

Obviously conf.avail is missing for me with 2.19.26. If it's my
problem then it's bad, but if it's a general problem for 64-bit-Linux
then it's worse.

Best would be others with 64-bit Linux could do testing for:

\version "2.19.26"
\markup \override #'(font-name . "not a font") "\\<==what?"


or look, whether
lilypond/usr/etc/fonts/conf.avail/*.conf
exists at all.



Thanks a lot,
