good morning

I am new to using linuxmint, and I installed the kdenlive Version 17.12.3 that comes in the software manager; It's going well but one last project failed me. Try the kdenlive-20.04.1b-x86_64 app image version and it runs smoothly to render.
How can I install version 20.04 from the terminal?
I have tried with the commands:

sudo add-apt-repository ppa: kdenlive / kdenlive-stable

sudo apt-get update

but I still get version 17.12.3

Someone with more experience could help me, who can pass me the commands for the terminal.
best regards

Excuse me, I am using the google translator. I am Argentine (Spanish language)

usually the only way to have the Kdenlive 20.x on Linux is using the Appimages or to have an updated distro of Linux. (and 19.03 seems not too much updated) btw i'm talking about Ubuntu ... no idea for other distros.

It's easy - just follow this link and you can install the latest 20.04.3 version: https://www.flathub.org/apps/details/org.kde.kdenlive
