RunTime error with generate_tiles.py

[zsoooc]

I installed a tile server based on this tutorial: https://ircama.github.io/osm-carto-tutorials/tile-server-ubuntu/
I strictly followed the instructions and I use Ubuntu 16.04.1 clean install.
The server works, but there is an error when I want to run generate_tiles.py.

"Runtime Error: Failed to find font face 'Noto Sans Adlam Regular' in FontSet 'fontset-0' in FontSet at line 17 of '/home/user/src/openstreetmap-carto/style.xml

For some reason I couldn't get the Noto Sans fonts to work even though they were installed. Since the Deja Vu Sans fonts worked, I went into the XML file listed in your output and removed all references to fonts other than Deja Vu Sans in all of the fontsets.
