I newly installed Ubuntu alongside Windows on my laptop and no connection to the internet is available.
Ubuntu Version should be the newest and I am new to Ubuntu and wanted to get some experience in it. I tried e.g. sudo apt-get update and other suggested commands but no packages (so every installation doesn't work) were found and connections to some http-resources failed also, because the site couldn't resolve.
Any hints for the solution would be awesome!
If any information is needed, just let me know
