Comment 1 for bug 1992110

Thanks for reporting the bug and tracking down the likely culprit. This is related to a collection of rebuilds for 20.04 Focal and older, including of OpenCV, that were pushed to both the Blender and digiKam PPAs yesterday. The rebuilt packages are all with GDAL 3.4.1 as found in the latest LTS (22.04 Jammy).

There were approximately 20 packages involved in the upgrade process and gdcm was intended to be copied to both the Blender and digiKam PPAs, but it was accidentally missed (as you have learned!). So the new required gdcm 3.0.14 version has just now been copied (from ppa:savoury1/graphics) to both the Blender and digiKam PPAs and should be published and available shortly.

This should hopefully fix the issue with installation of the latest Blender version 3.3.1 on your 20.04 Focal system.
