Error during install RTAI Kernel on Debian 12

Try just installing the Linuxcnc package, after removing the docs package

wget linuxcnc.org/dists/bookworm/2.9-rt/binar...xcnc_2.9.2_amd64.deb

sudo apt install ./linuxcnc_2.9.2_amd64.deb

The issue is with the docs package, which isn't really required for a basic install.

That fixed my issue. Thank you.

I'm trying to upgrade from linuxcnc 2.8 to 2.9 rtai on Debian 10 and I'm also having the same problem, the strange thing is that I've done this same procedure several times and it always worked, now it doesn't work anymore

What isn't working?

Are you definitely installing matching kernels and linuxcnc packages?

I like to use Linuxcnc 2.9.2 with Debian 10, so I always did the same installation, I installed the linuxcnc 2.8.4 preent iso and used synaptc to update to 2.9 rtai, it always worked, now when I tried today it gave me a error

E: /var/cache/apt/archives/linuxcnc_1%3a2.9.2_amd64.deb: trying to overwrite '/usr/share/applications/linuxcnc-documentation- es.desktop', which is also in the linuxcnc-doc package -es 1:2.8.4.1.gb7824717b

and does not update

I always used it with kernel 4.19.195, I always downloaded the kernel along with the update, now I didn't do that
