[digiKam-users] Digikam 7.8.0 doesn't update thumbnails and folders

[Chris Deuchar]

Hi again,  I have just emerged from a succession of trials which have
finally resulted in me having a properly working version of digikam 7.9.0
using the appimage file I was pointed at.
The way I got here was somewhat convoluted and time consuming but I will
explain in case it helps/guide anyone else.
1. After the previous exchange, I uninstalled my working - but none
thumbnail scanning - snap version of 7.8.0.  I replaced it with the flatpak
version.  This changed nothing.
2. So, I removed it again and also did a whole series of file deletions and
so on variously using synaptic package manager and my file manager.
3. I reinstalled the flatpack version (multiple times!) but always got the
same result - digikam could now *only* see my username folder containing
the Pictures folder. - ooh and the waste bin - nothing else. No other
folders at all could be found or made visible.  This was obviously a
considerably worse situation than I started with where I could see all the
folders up to where I believe the 7.7.0 to 7.8.0 update occurred.
4. I attempted to purge everything - including using command line strings,
synaptic and file manager - after removal of all the visible installations.
5. Reinstalled the flatpack version one last time <G> - still only the
<username>/pictures folders visible.
6. Used appimage 7.9.0 - which ran, found everything missing and produced a
complete set of thumbnails - all within two hours.
7. Removed the flatpack version 7.8.0 in 5, above
8. Checked appimage 7.9.0 still working?  - Yes! - and it also seems
noticeably quicker.
9. One final point of note; the appimage 7.9.0 was clever enough to know of
one folder which I did not want scanned.  This was despite all the
deletions and purgings referred to in 4. above!  So obviously I had not
been as thorough as I had hoped/expected!

So, my conclusion is that version 7.8.0 was flawed in some way that
manifested on my machine.
When a newer flatpack version arrives for 7.9.0, I'll give that a go...

Thanks for the help along the way
Chris
