Fonts for OSD not found (Pi)

[Prutsium]

Octoprint version: 1.4.2
Octopi version: 0.18
Octolapse version: v0.4.1+u.88aa71f
Python version: 3.7.3

I made recently a fresh install of OctoPi and noticed some issues with fonts as Octolapse dont see any fonts anymore.
Font-Config is installed and fc-list give this result:
pi@octopi:/ $ fc-list
/usr/share/fonts/truetype/dejavu/DejaVuSerif-Bold.ttf: DejaVu Serif:style=Bold
/usr/share/fonts/truetype/dejavu/DejaVuSansMono.ttf: DejaVu Sans Mono:style=Book
/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf: DejaVu Sans:style=Book
/usr/share/fonts/truetype/dejavu/DejaVuSans-Bold.ttf: DejaVu Sans:style=Bold
/usr/share/fonts/truetype/dejavu/DejaVuSansMono-Bold.ttf: DejaVu Sans Mono:style=Bold
/usr/share/fonts/truetype/dejavu/DejaVuSerif.ttf: DejaVu Serif:style=Book

The log of Octolapse reports an error for a font but i cant select or deselect any font:

How could i fix this?

[FormerLurker]

Try installing from this URL in the plugin manager: https://github.com/FormerLurker/Octolapse/archive/devel.zip

Also, what version of python are you running? I need to test this in both versions (2.7 and 3+)

[Prutsium]

As usual printer is running now but will do when it finishes.

Python version: 3.7.3

[FormerLurker]

Sounds good. And use this url instead: https://github.com/FormerLurker/Octolapse/archive/5a4b744dbf6105d426c35eb449076c9c101e9dc2.zip

It's safer since I may be pushing more to devel.

[Prutsium]

Yeah seems to fix it :)

Thanks for the quick reaction and solution.

[FormerLurker]

Awesome! If you have a python 2.7 instance, I'd love to see if it works there too. I will eventually get around to it :)

[Prutsium]

Pitty enough my both systems are Python 3 already :)

[FormerLurker]

Tested in python 2.7, and is working! Closed :)
