Installing ethercat repositories

Try enabling UEFI in BIOS.
 

My motherboard is very old and doesn't support UEFI. Maybe I should use one that will support it.

The "EFI variables are not supported on this system" has nothing to do with BIOS setup.
This is common kernels RT problem (efivars disabled in config).
The solution is to add "efi=runtime" to the kernel parameters (once at boot or to /etc/default/grub).

You have the right to have a computer museum, but do not require anyone to help you maintain it.

"efi=runtime" is added and the same "EFI variables are not supported on this system" error appears.

Would you suggest a hardware that is guaranteed to work with the latest repositories and EtherCAT?

Some second hand computer after leasing.
I use for ethercat HP 705 G3 AMD Radeon R7 A10-8770.
It is not newest, but small and powerfull.
In my opinion, you can buy very good computer for LinuxCNC for 50-100 USD.

Another error after trying to "sudo apt upgrade".

Error: Failed to fetch www.linuxcnc.org/dists/trixie/2.9-uspace...pace_2.9.9_amd64.deb   404  Not Found [IP: 69.163.143.134 443]
Error: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

Why is that happening?

The good thing is that I managed to install the ethercat. But I used another computer with UEFI for the purpose.

Thank you very much in advance!

This is not good. I need working LinuxCNC EtherCAT master very soon. How can I compile this? Maybe install older version of LinuxCNC?

This has nothing to do with ethercat. 2.9.10  Debs think is available on GitHub releases but you can compile it yourself
