LinuxCNC on Debian 10 Buster quick and easy install

@mookins,
That will also work, thank you.

I want to install new machine on Buster and want to be sure for this. Sorry if i ask wrong question but i'v read from developers mails, that in LCNC code in this moment something is not compatible with buster because it is not supporting Python 2.xx Only support 3.xx . Is this true and did i will have some problems in running the software and his futures with Buster..

tommylight keep the great work..

Thanks...

I am aware that buster had some issue, but there is no issue in using linuxcnc at all, maybe if you want to use it for development it might have issues, but i am not using dev on the 2 PC's i have Buster installed.

Great to now ..

Thanks

Debian allows you to have both Python 2 and Python 3 on a system without any issue. The binaries are named python2 or python3 etc. You can see here www.debian.org/doc/packaging-manuals/pyt...olicy/ch-python.html to see how it all works.

Hi,
first of all, very good manual. With this, the installation of Debian 10.3 is very easy

I had a question, hope you can help me. I tried to reduce my Jitter with the following manual:

wiki.linuxcnc.org/cgi-bin/wiki.pl?The_Is..._Parameter_And_GRUB2

the following works very well in my old Linux installation with "Wheezy". But not under "Buster"

As shipped, Ubuntu distributions using GRUB2 include a set of configuration script files in the directory /etc/grub.d/ with names 00_header, 05_debian_theme, 10_linux, etc. These files are processed in numerical order as a component of GRUB2 creates the file grub.cfg. Kent's solution is to add to this directory a new file 07_rtai that scans for linux-rtai kernels and for them only creates boot menu entries including the "isolcpus=1" parameter. Kent uploaded a copy of this file at 07_rtai.

This file has been updated to add support for Ubuntu 12.04, LinuxCNC 2.6.x, as it now looks for kernels ending not only in "rtai", but also "rtai-686-pae".

Assuming one has downloaded this file to one's home directory, the following commands will implement it.

<username>@<hostname>$ sudo cp 07_rtai /etc/grub.d
<username>@<hostname>$ sudo chmod +x /etc/grub.d/07_rtai
<username>@<hostname>$ sudo update-grub

At this point, one should find that the file /boot/grub/grub.cfg contains menu entries for the linux-rtai kernels with the boot parameter "isolcpus=1" set at the end of the kernel line. If the default file 10_linux is present and executable, the same linux-rtai kernels as well as all other installed linux kernels will also occur in following menu entries without this additional parameter present.

Kent Reed created the file 07_rtai by editing a copy of the distributed file 10_linux. Following Kent's introductory block of comments, all changes to the logic of 10_linux have been marked in 07_rtai by comment lines beginning #KAR:.

But now, with Debian 10.3 it seems, that it don´t copy the "isolcpus...." entry into the grub boot parameter.

Do you have the same problem, and an idea, how I can solve it?

Thank you.
