"gksudo" requirement for GUI install on Linux
I am using a special version of Ubuntu-20.04-desktop-amd64-mac-mattgradient.com.iso
This version allows me to install Ubuntu to a MacBook 2008 white.
It has taken me many tries in creating a DVD’s to get it right.
You have to download the following .debs in order to fix the gksudo missing problem during
installation.
gksu_2.0.2-9+b1_amd64.deb
libcanberra-gtk-module_0.30-3_amd64.deb
libgksu2-0_2.0.13_pre1-9+b1_amd64.deb
libgnome-keyring0_3.12.0-1+b2_amd64.deb
libgnome-keyring-common_3.12.0-1_all.deb
libgtop-2.0-10_2.34.2-1_amd64.deb
https://packages.debian.org/stretch/amd64/ for a 64-bit OS
Please note that this installation of Ubuntu-20.04-desktop-amd64-mac-mattgradient.com.iso
will completely wipe out the OSx operating system.
