there's no "ttf-freefont" package.

Running tesla_dashcam prints:

$ ~/.local/bin/tesla_dashcam
Font file /usr/share/fonts/truetype/freefont/FreeSans.ttf does not exist. Provide a valid font file using --font or disable timestamp using --no-timestamp
You can also install the fonts using for example: apt-get install ttf-freefont

however that package doesn't appear to exist (I'm on Ubuntu 20.04.3 LTS):

$ sudo apt-get install ttf-freefont

Package ttf-freefont is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'ttf-freefont' has no installation candidate

(I'm not sure which package it thinks refers to ttf-freefont. apt cache depends seems to be saying it refers to itself)

Looks like for ubuntu that font is located in package fonts-freefont-ttf

sudo apt update
sudo apt install fonts-freefont-ttf
