What's about this file using digiKam AppImage bundle 5.4.0 pre release given at
this url :

Comment 3 caulier.gilles 2018-11-11 08:31:09 UTC
This problem is certainly due to CIFS non support in Exiv2. Look this Exiv2 forum entry :

Comment 4 caulier.gilles 2020-08-02 14:44:39 UTC
digiKam 7.0.0 stable release is now published:


We need a fresh feedback on this file using this version.

Best regards

Hi Yuri and happy new year,

Can you reproduce the problem with digiKam 7.5.0 pre-release AppImage bundle
for Linux available here :


Best regards

Comment 6 caulier.gilles 2023-04-21 05:54:18 UTC

digiKam 8.0.0 is released. This file still valid ?

Gilles Caulier
Comment 7 caulier.gilles 2023-10-12 14:37:03 UTC

What's about this file using current 8.2.0 AppImage Linux bundle ? It's
reproducible ?


Note: bundle is now based on Qt 5.15.11 and KDE framework 5.110.

Thanks in advance
