Hi, I don't use Darktable that often and when I tried to this morning it... well, it just didn't.
Machine *was* Ubuntu 14.04.LTS and has been upgraded to 16.04.LTS, now: 4.4.0-66-generic #87-Ubuntu SMP x86_64 GNU/Linux (Dual 4-core proc; 16Gib RAM). Darktable was installed when the OS was 14.04 and has been used subsequent to upgrade. The Errors.... >From Syslog: Mar 14 11:30:42 nine gnome-session[2520]: (gnome-software:2721): As-WARNING **: failed to rescan: Failed to parse /usr/share/applications/darktable.desktop.dpkg-new file: cannot process file of type text/plain Mar 14 11:30:42 nine gnome-session[2520]: (gnome-software:2721): As-WARNING **: failed to rescan: Failed to parse /usr/share/applications/darktable.desktop file: cannot process file of type application/x-desktop Mar 14 11:30:46 nine gnome-session[2520]: (gnome-software:2721): As-WARNING **: failed to rescan: Failed to parse /usr/share/applications/bamf-2.index file: cannot process file of type text/plain Debug: ~$ /usr/bin/darktable -d all [memory] at startup [memory] max address space (vmpeak): 317332 kB [memory] cur address space (vmsize): 317332 kB [memory] max used memory (vmhwm ): 20028 kB [memory] cur used memory (vmrss ): 20028 kB /usr/bin/darktable: symbol lookup error: /usr/bin/../lib/x86_64-linux-gnu/darktable/libdarktable.so: undefined symbol: _ZN5Exiv213XmpProperties10registerNsERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEES8_ That file... ~# file /usr/lib/x86_64-linux-gnu/darktable/libdarktable.so /usr/lib/x86_64-linux-gnu/darktable/libdarktable.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]=c0c8f07f10ed3c9928ea7b9b32caed116bd29acf, stripped ~# ls -l /usr/lib/x86_64-linux-gnu/darktable/libdarktable.so -rw-r--r-- 1 root root 2922920 Jan 31 21:12 /usr/lib/x86_64-linux-gnu/darktable/libdarktable.so What I've done: update Darktable; purge Darktable, install Darktable from "deb http://ppa.launchpad.net/pmjdebruijn/darktable-release/ubuntu xenial main" — all with same errors Purged Darkable again and tried to build from source [this failed, another question for another time] installed again as above. Still failed. Now I'm stumped.
