Issues installing LinuxCNC was created by besi99
Hello,
I just installed my first Linux version on an old Thinkcentre i have laying around. Iam planning onbuilding a new CNC using LinuxCNC so I thought maybe I can and lear how to use it before i finish my CNC. Kinda just to get used to Linux.
So after like 2 hours I finally managed to get debian 12.10.0 running on my Thinkcentre. Then I started to follow the instructions on the LinuxCNC page.
I did the updates:
sudo apt-get update
sudo apt-get dist-upgrade
Then I installed the Preempt-RT kernel
sudo apt-get install linux-image-rt-amd64
everything worked fine. After the restart it selected the right linux RT version.
So the issue starts here.
If i click on the link for the linuxcnc-install.sh file it doesnt download anything. So where exactly do I get the script? Iam probably just to stupid to understand it.
Also chmod +x linuxcnc-install.sh doesnt work. I have even tried opening an txt.file and naming it linuxcnc.install.sh with the script from the browser. But still nothing.
Found another thread with simillar issue
$ chmod +x besnik/home/Downloads/linuxcnc-install.sh
Or better yet
$ cd besnik/home/Downloads/
$ chmod +x linuxcnc-install.sh
Always says No such file or directory.
Does anyone have an idea what I am missing I can already deel its something easy to fix I just dont see it. Kinda embarrassing asking for help

Both seem wrong, should always be....
$ chmod +x besnik/home/Downloads/linuxcnc-install.sh
....
$ cd besnik/home/Downloads/
....
/home/user_name/Downloads
or in your case
/home/besnik/Downloads

You had the directory tree order wrong. You typed "cd home/besnik/downloads/" and it needs to be "cd besnik/home/Downloads/". Also Linux is case sensitive so the capitol leter "D" is also important.

home and besnik are in the wrong places again and Downloads starts with upper case D. Linux is case sensitive so D and d are not the same.
Copy and paste from here:
Copy and paste from here:
cd /home/besnik/Downloads
sudo chmod +x /home/besnik/Downloads/linuxcnc-install.sh
./linuxcnc-install.sh

Man I definetly need to take some sleep....
It definetly did something this time. Thanks for youre help guys. I was ready to just go back to Estlcam and windows haha.
If I go to Applications -> CNC there are only two options there is Documentation and G-Code Quick Reference. There is no LinuxCNC application does that mean somthing went wrong with the installation? I did a restart same thing.

Check the "accessories" submenu for LinuxCNC stuff, sometimes they end up there.
