I downloaded this Jun28 and got verson 5.1.6 which is the latest edition of this software which I installed through the Software Manager. The website has instruction to manually install by adding a repository which I didn't need to do. I found a tutorial by Digi-Key on Y.T. which is why I installed this. Giving 5 stars while I learn.

Latest versions are available on Flatpak. What is there to say? KiCad is a phenomenal PCB and schematic capture software with top notch features. Especially in the last couple years KiCad has improved by leaps and bounds thanks to a wonderful developer community.
