Does this mean that without bending over backwards to add custom repositories, RawTherapee is not available in OpenSUSE, Arch, Debian, Fedora, RHEL, CentOS, Ubuntu, Mageia, etc?
No route matches {:action=>“show”, :controller=>“package”, :package=>“rawtherapee-dbgsym_5.7-1dhor~bionic_amd64.ddeb”}, possible unmatched constraints: [:package]
Well if you step up as the maintainer you can even submit it to openSUSE Factory and Leap afterwards. then it will be part of the normal distribution.
I already offered you graphics:rawtherapee (similar to what we do for darktable) where you can do the builds for all other distros. home: has this warning for users (for a good reason normally).
