@DPITTI I don't know why you got upset this time, but as I told you you are free to use what ever you want. Using and testing UT is a personal choice and if you are not satisfied with your experience then you can just put another OS. You are welcome to come back and try out UT whenever you want. Have a great day and I hope you find the right OS for your needs.

@Lakotaubp Thank for the replay I got an answer of what is the problem. The kernel patch version is higher than 288 and that's why the libertine does not work. Unfortunately the port is not maintained anymore , so I will try to build the port with proper kernel patch version to make it work and if I have time I will try to migrate the port on 20.04
