I am following the Stephen Schipper tutorial on installing xschem, pdk, and ngspice. The issue is the xschemrc file looks really different from the way it shows up on the video. Here is the video: and the part I am stuck on is at 16:37. I did it the way described in the video but with an equivalent directory that matches up with what i have done up until that point.

@asdf asdf please follow this link. It is more updated

This didn't resolve my problem. Do you recommend I use sudo apt-get remove --purge xschem? I would need to start over right?

Yes, don't use the xschem that is provided in Linux distributions, it is realy too old, and it takes too much time to push the maintainers for an update. Build xschem from the github repository as explained in the above link, or use a pre-build docker image with all the tools installed.
