Well, it’s not in the Debian repos like they claim on the web page.
Because Trixie is about to be released as Debian 13, SID & Testing are mostly one in the same.
So I tried the manual install, I even followed the instructions. So, the first problem is a lot of the packages that are required to run it aren’t available in Debian. some of the commands (ninja -C, for example) won’t run and is a program that isn’t in the Debian repos. I tried to finish out the installation and it didn’t work, I wasn’t able to launch it by any of the commands they list and ended up giving up on the install.
Oh well, it looked cool maybe the project will mature enough it can be added to other distros besides Arch & NixOS. I guess that’s life in the big city.
