Desktop installation gauge not updating

[rogierhofboer]

On Linux Mint 17.2 Cinnamon 64-bit the desktop installation gauge is not updating, due to an invalid number error.

Log:

[ o.k. ] Installing desktop [ XFCE ]
/home/rogier/armbian/lib/desktop.sh: line 74: printf: 3.00: invalid number
/home/rogier/armbian/lib/desktop.sh: line 74: printf: 7.00: invalid number
/home/rogier/armbian/lib/desktop.sh: line 74: printf: 10.00: invalid number
etc.

I am not supporting Mint 17.2. ... Ubuntu Trusty is needed that everything works as expected. I am slowly fixing things for Vivid and Debian Jessie.

When using my existing Ubuntu Trusty 14.04.3 LTS 64-bit Linux installation, this error still occurs only for the "installing desktop" gauge (but not for the installing packages gauge).
My guess it is due to Dutch locale settings (which is using a comma as decimal separator instead of a period).
