I’m getting this error when running webbrowser.open(userPath) from my Python application

qt.qpa.plugin: Could not find the Qt platform plugin “xcb” in “”
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Hi
I have a question but I couldn’t find the answer in google.
How we can find out if all the required packages are installed in ubuntu or not?
Like when in I install unubtu for the first time yesterday, I use sudo apt update and also sudo apt upgrade to install packages but I think still some packages hadn’t installed yet.

apt-cache search .terms.
and
apt-cache show .pkg.

there will be many packages that arent installed

djdisodo1 2022-08-08 11:22:05

djdisodo1 2022-08-08 11:22:43
dlna is fine it just requires http video link that’s streamable
djdisodo1 2022-08-08 11:22:50

alexmb7 2022-08-08 11:22:52
dlna or dnla or whatever plus streaming opts i dunno
alexmb7 2022-08-08 11:23:02
djdisodo1 2022-08-08 11:22:50
like streaming http link in vlc

that may also do http

alexmb7 2022-08-08 11:23:11
instead of this dlna
alexmb7 2022-08-08 11:23:27
id say it will do
djdisodo1 2022-08-08 11:23:30
dlna uses http
alexmb7 2022-08-08 11:23:30
a simple httpd
alexmb7 2022-08-08 11:23:37
when accessed sends ffmpeg
