==> Packages to install (eg: 1 2 3, 1-3 or ^4)
I searched for a while, but can’t find anything regarding that package outside of rasberry pi os. From my research the binary is provided by the package libcamera-apps. Which again is only packaged by rasberry pi os and according to repology, fedora. Out of all the linux distros. I’m only finding two of them that might have that package. You may have to build it yourself if you really need it.
