DT from Pascals PPA depends on
liblensfun0 (>= 0.2.8)

So, in order to be able to install DT, a suitable version of lensfun has
to be installed, too. If this is not possible, the installation of DT
will fail.

This is because DT depends on liblensfun0 and you installed liblensfun1.
And liblensfun1 most probably will clash with liblensfun0 so this gets
deinstalled or simply broken.

With kind regards

That's what I've been trying to tell people; I have the same problem. No
seems to understand.

Tobias, although I appreciate your effort to help me, your information
doesn't address either of my issues.
Issue 1: installing DT2.4.2 directly from DT PPA does not seem to install
lensfun (any version).
Issue 2: installing lensfun 0.3.2 either before or after installation of DT
2.4.2 yields the problems I first reported: no drop-down list of lens
choices AND no persistence of selection.

If the version of lensfun your copy of dt was built with is too old for your 
lens you can either try to manually copy the new data over or install the new 
lensfun and then compile dt for it. Alternatively you can look for some 
package that already does so. Like Pascal's PPA. It comes with a patched copy 
of lensfun.

[darktable-dev] Lens Correction

[Maurizio Paglia]

Hi,
my module 'lens correction' works no more.
I cannot see ANY camera brand in the combo list, it is empty...
Also images previously developed have the module activated but with NO 
correction.

Thank you,

Maurizio
