It really sounds like you have an issue with your internet connection. can you ping that IP address?

Yes it pings with average time of 150ms but still can't find the files, there may be existing setup problems, here is what the update produces:

When you installed Linuxcnc ISO you were not connected to the internet so its looking on a CD ROM that does not exist.
I would suggest you reinstall Linuxcnc while connected to the internet, then do this again

It appears something has broken since last friday. I also am unable to install now, getting the same missing files you are seeing.

My linux ignorance really shows in these scenarios, I also need very clear step by step instructions. I'm currently blocked again and relying on an older 2.8.2 iso that was packaged up by Grotius on the forum:
github.com/grotius-cnc/LINUX_RTOS/releas...age-amd64.hybrid.iso

That iso has a package that you just need to double click on the desktop that installs all the ethercat stuff and you just need to edit the ethercat.conf file and youre good to go.

I wiped the disk and reloaded LinuxCNC 2.9.2 but still get invalid signatures
