Ethercat installation from repositories - how to step by step

with the latest linuxcnc 2.9.8 ISO-install on a Lenovo M720Q I get compile errors. Any ideas?

You could try deleting the igH.sources (name might be a  bit wrong) from /etc/apt/sources.list.d

And follow this process which I have tested with 2.98 in the last week or so.
github.com/linuxcnc-ethercat/apt

This is going to become the official repository and Ethercat version to use for linuxcnc

Im fairly new to linux cnc, trying to do a clean install in a mini pc of the 2.9.8 iso but im encoutering these errors when trying to install ethercat the way this thread discribes, can someone help?

Thanks, this repo works for me on 2.9.8 (the default is in the file /etc/apt/sources.list.d/science_EtherLab.list and gives errors)
 

after looking through the logs a bit more, I figured that the solution that rodw recommended to awallin also fixes my errors, thanks anyways

I will update the first post so wish me luck!

There was some talk of publishing a new 2.9.x version to fix some bugs. If that is the case, I will send in a PR to update the repos in the installer based on the link above.
