Amusing. I had no issue installing on chromeos HOWEVER I was using an old copy of the linux_installer.sh script...

My version was missing the check for the presence of libfreet

def check_for_recent_freetype():
    import ctypes
    try:
        f = ctypes.CDLL('libfreetype.so')
    except OSError:
        raise SystemExit('Your system is missing the FreeType library libfreetype.so. Try installing the freetype package.')
    try:
        f.FT_Get_Color_Glyph_Paint
    except AttributeError:
        raise SystemExit('Your system has too old a version of the FreeType library.'
                         ' freetype >= 2.11 is needed for the FT_Get_Color_Glyph_Paint function which is required by Qt WebEngine')

I do NOT have libfreetype.so present; but I do have libfreetype6.so

It's worth noting this addition to the install script was made today.
