Hi,
I am using Ubuntu 18.04.3 LTS 64 bit OS. Recently Kdenlive released a new version, which is awesome. Therefore I want to use it. Unfortunately,

Code: Select all

sudo apt install kdenlive

is installing 17.12.3.

I used snap in the following way-

Code: Select all

sudo snap install kdenlive --candidate


The above command is given at the following page

While starting kdenlive, I am getting the following error message.



Please note that Kdenlive does not open.

I tried installing MTL using

Code: Select all

sudo apt install melt

, but I still see the same error.

It is difficult to upgrade Ubuntu since this is the latest LTS version. How to install the latest Kdenlive on Ubuntu 18.04.3 LTS?

In https://kdenlive.org/en/download/ I see “Snap support has been dropped until maintainers are available.”

Can you use any of the other cross-distribution solutions listed in https://kdenlive.org/en/download/?

Otherwise, compiling from sources may be the way to go. It may sound daunting at first if you have never done it, but for applications like Kdenlive it should not be too hard.

Thanks, @Gallaecio, for the suggestion. I tried installing 19.04. Please see below-

ravi@lab:~/tools/kdenlive$ git checkout Applications/19.04

Your branch is up to date with 'origin/Applications/19.04'.
