Live/Install for Debian Stretch, RT-PREEMPT, LinuxCNC 2.7.x

works fine including use of samba

LPT with Axis works perfect

for installing CamPY for LinuxCNC - Camera Edge Finder
as nicbit wrote in category debian-stretch-tricks
please install python-apt using the command:
sudo apt install python-apt

works perfect

I need to make some changes in the kinematics file so it will suit my corexy system. It means I have to be able to install linuxcnc -dev. Is this process can be done with this version of linuxcnc and debian iso file?

Hi,
as TKR confirms my fears about usage of RT-PREEMPT and AnnoyingMutt shared links to wheezy sources,
so I'll use wheezy with edited /etc/apt/sources.list (attached the edited list - unzip before use). This works fine.

To get it working give the commands (in terminal):

cd /path/to/your/new/sources.list
sudo mv /etc/apt/sources.list /etc/apt/sources.list.orig
sudo cp sources.list /etc/apt/sources.list 
cat /etc/apt/sources.list
sudo apt-get -o Acquire::Check-Valid-Until=false update

Check-Valid-Until=false is needed, because some release file has been expired.

i think this is in the correct path to solution, but i have a lots of errors on updating.
somewhere i read that one has to make the Check persistent doing:

sudo "your preferred editor" /etc/apt/apt.conf

add a line to it (if apt.conf is not present this will create one)
LINE
Acquire::Check-Valid-Until "0";
LINE

after that
sudo apt-get -o Acquire::Check-Valid-Until=false update
sudo apt-get update

my actual sources.list look like this
deb archive.debian.org/debian/ wheezy main non-free contrib
deb-src archive.debian.org/debian/ wheezy main non-free contrib
deb archive.debian.org/debian-security/ wheezy/updates main non-free contrib
deb-src archive.debian.org/debian-security/ wheezy/updates main non-free contrib

# wheezy-backports
#deb ftp.us.debian.org/debian/ wheezy-backports main contrib non-free
#deb-src ftp.us.debian.org/debian/ wheezy-backports main contrib non-free

The wheezy backports was used to install mate desktop, i have to comment it not knowing how to do it right ;(((

regards rick

Lets just have one solution, confirmed by Adin/Mods and make it sticky and leave it at that.

I have next lines in /etc/apt/source.list:

And I added one file with name: "10no-check-valid-until" in /etc/apt/apt.conf.d/ with below line inside:

A restart may be necessary.

This works for me, hope this help.
