I can't connect to the internet with my Lubuntu 18.04. It shows the wifi adapter with the signal bars and says that it's connected, but Firefox says: can't connect to server and Sudo apt-get update says Failed to Fetch.

Take the following steps:
- open a terminal by pressing Ctrl+Alt+T
In the terminal type:
ping www.google.com
- You will probably get time out as reply or not a reply at all
- Press Ctrl+C to stop the ping command.
In the terminal now type:
ping 1.1.1.1
This will try to ping Cloudflare's DNS. If you get replies then the problem lies within your DNS server.
If you don't get a reply then you are not connected to the Internet through your router. (which is en issue outside of Ubuntu and off-topic here)
