LinuxCNC on Debian 10 Buster quick and easy install

It's a Dell Vostro 220 I bought a few years ago for cheap and has been a workhorse running LCNC v 2.7 since 2017ish.

I got it to boot and completed through;

cd Downloads
sudo gdebi python-gtksourceview2_2.10.1-3_amd64.deb

Now at the next point I am getting the message;

plaz@plaz-pc:~/Downloads$ sudo gdebi linuxcnc-uspace_2.8.0~pre1.5649.gec411a428_amd64.deb
gdebi error, file not found: linuxcnc-uspace_2.8.0~pre1.5649.gec411a428_amd64.deb

The required file is located in my download folder along with the one that has already processed, any idea what might be the problem? I have tried both 2.9 & 2.8 versions to the same result.

The numbers seem to match. I only downloaded what was linked in the original post.

I did notice a discrepancy between was comes up when I enter the uname -a command and what is shown in the OP.

plaz@plaz-pc:~$ uname -a
Linux plaz-pc 4.19.0-8-rt-amd64 #1 SMP PREEMPT RT Debian 4.19.98-1+deb10u1 (2020-04-27) x86_64 GNU/Linux

vs.

Should say "Linux some_name 4.19.0-8-rt-amd64 #1 SMP PREEMPT RT Debian 4.19.98-1 (2020-01-26) x86_64 GNU/Linux
"

I'm sorry but I do not understand.
I tried this on another computer with 64 bit system with the same result.
I followed the directions correctly (I think) so what do I need to do to get it working?

I went another way and installed the linux mint you linked to here forum.linuxcnc.org/9-installing-linuxcnc...er-mint-iso?start=10 without any problem.

Thank you!
