[digiKam-users] Camera and lens ID failing for lens correction

[Gilles Caulier]

Maik,

I will try to found a work around the network bandwidth COV-19
restriction with gitlab repository to update the bundles.
As all my computer has already a copy of code source, i don't need to
cleanup and reload all before to build source code.

I need to fix the rules in scripts and test.

Gilles
