Raspberry Pi 4 with PlasmaC

buildbot.linuxcnc.org/dists/buster/2.8-rtpreempt/binary-armhf/
Get the latest build from ther if you want 2.8
or
buildbot.linuxcnc.org/dists/buster/maste...reempt/binary-armhf/
if you want 2.9

Is this the latest 2.9 ?
buildbot.linuxcnc.org/dists/buster/maste...g64994a259_armhf.deb

So how do I install (used to iso's )

Sorry for the late reply, had guests.
Yes that is it, double clicking on it should open gdebi so just clicking on install should do.
If there is no gdebi:
sudo apt-get install gdebi
If it complains about dependency not satisfiable, enable the repositories in software sources.
Try again.

Thanks, no gdebi now installed the deb package.

But... this morning NO HDD boot but a lot of ext4 errors and no VNC.

Back to SD and all is well.

I do not know if you have seen already how to prepare pi4 for ssd.

I have no SSD only 2.5" HDD and it will have to do for now.

Trying to setup RPi headless output via VNC on my tablet with 1280x800 but I can not find the correct settings in RPi to get full Gmoccapy on the tablet.

Any hints on how to get this working is much appreciated.
