i’m on ubuntu 17.10 with darktable 2.5.0 (git master) and lensfun 0.3.2. Lensfun lists my desired lens (Nikkor AF 18-35mm f/3.5-4.5D IF-ED) online, the distortion profile is available. I wrote desired as i do not actually have this lens. I’m using the newer AF-S version (NIkkor AF-S 18-35mm f/3.5-4.5G ED) and would like to apply the distortion correction of the old lens to my photos (i’m guessing they should be pretty similar). However, the old lens is not shown in darktable when i try to apply the profile manually.
