Hi all, I'm trying to Dino XMPP. I tried to use the sudo apt command and it gave me an error. Then I downloaded the deb package and when I ran it, my software app kept spinning and spinning. Then I followed another topic's advice to use sudo apt update, and it gave me an error. I also tried using the sudo apt to reinstall gnome, error.
I then I read that I could use gdebi to help make downloading deb packages easier, so searched for it in my software app and it's not there. So I ran the command suggested sudo apt install gdebi, and I get an error.
Also, I have a red exclamation mark at the top right of my computer after restarting and it says an error occurred and to run Package Manager or terminal apt-get - but no further instructions.
Any help, sorry, been new to Linux for a month and it is a massive learning curve. I feel like I can spend 4 hours granting access to a new USB or installing a new file sometimes.
