I am trying to install a newer version on my Ubuntu 18.04, but it somehow doesn't let me. The version I have installed and that is natively available from the repos is 17.12.3. I want to upgrade to 19.12.3 to open a project file from a friend. In order to do that, I added the launchpad ppa of kdenlive to my system:
$ sudo add-apt-repository ppa:kdenlive/kdenlive-stable
Enjoy latest Kdenlive release!

Reading package lists…Done
But after that, I still have only the old version available:
$ apt-cache madison kdenlive
kdenlive | 4:17.12.3-0ubuntu1 | http://de.archive.ubuntu.com/ubuntu bionic/universe amd64 Packages
What can I do ?
