Recently migrated from Fedora to Ubuntu, and immediately noticed that a) ubuntu’s darktable official package is old, and b) ubuntu’s exiv2 library is totally obsolete (1-2 years old or so) and missing a bunch of lens and cameras. This impacts darktable’s cam/lens detection.
I found Pascal’s PPA, that brought the latest and greatest darktable but unfortunately Pascal built against the same old exiv2 release so that issue remains. I can guess updating exiv2 is not trivial. I tried a quick hack with Debian’s experimental packages (that are already in 0.26: exiv2, libexiv2), command line exiv2 works and detects the new cams/lenses but darktable didn’t take notice. I guess it’s built against the old version and the old lib version is still there.
Is there another 3rd party PPA (or snap) that people use for darktable that brings a more recent exiv2?
