I have been using darktable for sometime now on Debian. But after I re-install the operating system, darktable does not find my lens automatically. Instead I have to choose the lens manually every time I want do lens correction on an image. My lens is a Nikon DX VR AF-S NIKKOR 18-55mm 1:3.5-5.6G II
Any ideas why darktable behaves the differently?
I found that back then I had installed via the backports of debian so after removing the current version. I install the darktable via the backports and now I have the 2.2.1 but the problem still exist.

in Darktable I'm selecting Nikon, Nikkor 18-55mm f/3.5-5.6G AF-S DX VR isn't that correct?
I manually install the lensfun and run the update command. But darktable still does not select the lens automatically.
