--- Comment #9 from Vincent Danjean <vdanjean...@free.fr> --- Yes, it was my fault. Before opening this bug, I tried to execute the upgrade commands from /usr/share/digikam/database/dbconfig.xml As I was connected as root (and not digikamuser), I did not see the permission problems. But I executed all the command (the last two ones removed the columns). Adding them back allows digikam to upgrade the database until v15. Many thanks for your help. I will open a bug report on Debian so that the permission problem be documented more visibly. You might also want to improve the error message and to suggest to re-run digikam with 'QT_LOGGING_RULES="digikam.*=true"' in the error popup. The popup says "Please read the error messages printed on the console", but there was no messages without QT_LOGGING_RULES set.
