We are about to release privacyIDEA 3.6.
We currently have a development version 3.6dev4.
If you want to test this, you can install it from Ubuntu development repositories
You would need to change the repo to
deb http://lancelot.netknights.it/community/focal/devel focal main
for 20.04 or to
deb http://lancelot.netknights.it/community/bionic/devel bionic main
Do this at your own risk. You should not use your productive system or you should take a snapshot of your VM.
