I also tried a nightly build following: KiCad 5 and nightly builds for Fedora Linux – maybe fedora is different enough from centos that this won’t work…I don’t really know what I’m doing.
Thanks for trying to use my Fedora nightly builds! Unfortunately, they are currently not up to date. I’m working on some changes to the packaging scheme, and it will take another week or two until they receive the next update.
If you want to use nightly builds of KiCad on Fedora, please use the official Copr repository @kicad/kicad instead.
Independent of that: You can not use the Fedora nightly builds on CentOS (neither the old version 7 nor the current version 8). Some of KiCad’s dependencies are either outdated or not available at all on RHEL/CentOS.
If you want to play with the KiCad Python scripting interface and don’t mind to set up a dedicated (virtual) machine for that, I would recommend to use Fedora 33 and the stable release 5.1.9 (plus numpy, scipy, or whatever else you might need) from the Fedora repositories.
