downloaded ttf fonts from google, then copied to:

/usr/share/fonts/truetype

executed

fc-cache -fv
pm2 restart mm

it fixed the issue, however it means that MagicMirror has bug in its newest version…

think, yesterday after update was 87, two were done on purpose by me to check if it will bring up mm.

number is so high as I used pm2 resurrect to bring pir & mm sessions back from “old” stretch set-up as I have also upgraded pm2 itself…

will report anything suspicious :)
