I'll presume then that one must download the ISO from linuxcnc.org/downloads/ then perform an update procedure as there is no current ISO that can just be downloaded and run like the normal LinuxCNC install. Correct?
(I need to use the proper procedure if I make a YouTube tutorial video to push to my 3600 subscribers.)
You could download Debian 9 with LinuxCNC 2.7 and update to 2.8.
Or you could install Debian 9 or 10 (10 has a few issues with gscreen) from my instructions at gnipsel.com/linuxcnc/uspace/
And to update to 2.7... I believe... linuxcnc.org/docs/html/getting-started/updating-linuxcnc.html
So I have a plan... I'll do that as soon as possible.
