Installation on Ubuntu 20.04

[Rom888]

Is there an installation guide for Ubuntu 20.04?

My trial:

$ sudo apt-get install qt5-default
$ sudo snap install penguin-subtitle-player

$ penguin-subtitle-player
Qt: Session management error: Could not open network socket

Hi @Rom888, sorry for the late reply. It is the first time I hear this. Have you tried this? https://stackoverflow.com/a/62923539

Thanks @carsonip,
Now I see an icon in my tray, but how can I open settings?
Nothing happens if I click on it.

Does right click on the tray icon work?
