You should specify the extension of the font(e.g. otf).
This is my pull request with adding the extension .otf.

I used setfont instead of newfont and now it runs again. Adding the extensions to the font didn't help.

Could you tell me what you did exactly? In a bit detail?

Change newfont to setfont in the line with the error

Arch Linux users: You'll need https://aur.archlinux.org/packages/ttf-font-awesome-4/ (Version 4 in AUR) then edit awesome-cv.cls file at line 164: to have

\setfontfamily\FA[Path=\@fontdir]{FontAwesome}
% Set font for header (default is Roboto)
\setfontfamily\headerfont[
  Path=\@fontdir,
  UprightFont=*-Regular,
  ItalicFont=*-Italic,
  BoldFont=*-Bold,
  BoldItalicFont=*-BoldItalic,
]{Roboto}

\setfontfamily\headerfontlight[
  Path=\@fontdir,
  UprightFont=*-Thin,
  ItalicFont=*-ThinItalic,
  BoldFont=*-Medium,
  BoldItalicFont=*-MediumItalic,
]{Roboto}

@redragonx I am on ArchLinux, but I didn't need FontAwesome 4

$ pacsearch ttf-font
...
community/ttf-font-awesome 5.5.0-1 [installed]

Just the patching the .cls file was sufficient

I have the same error. But thanks to @ashwinvis, the patch fixes the problem.
