LinuxCNC + Orange Pi (allwincnc)

Thanks for the hard work.

I have some questions.
Which version of Armbian should I use? The latest?

Do I have to uninstall the previous version of Linuxcnc?

Latest Armbian Buster. No need to uninstall anything.

I tried to install it on a Orange Pi Pc with Armbian 5.10 but there were some error messages:

Are there any missing dependencies?

Try to install `installer/linuxcnc/linuxcnc-uspace_2.8.1_armhf.deb` manually.
And you will see what's wrong with dependencies.

After Installing linuxcnc-uspace_2.8.1_armhf.deb manually the installation finished with only one error message.

Question am I supposed to login as root before installing Linuxcnc? Or is there another reason for this error message?

I have now two Linuxcnc shortcuts on the desktop and can open both of them.

Install using non privileged user with sudo. Don't use root.

Found this error's reason inside install_linuxcnc.sh. Already fixed.
Update the installer and install emc again
