I am not very knowledgeable when it comes to Ubuntu. I wanted to install Jitsi because I didn't know there's a web application. While installing I came across an error which I tried to resolve but didn't managed to. And because I was told it was accessible via browser I ignored it. Now I want to customize my terminal but when trying to install new packages there is the following error: 

```none
