Hope you are doing well today!
I started using Linux a few months ago and am pretty much new into Linux and networking.
I am using Ubuntu 20.04 2.0 LTS and installed kubuntu on a friend of mine a couple of weeks ago.
I was with 20.04 recently but decided to upgrade to 2.0. My SSH was working just perfect before upgrading the distro, but now it's not connecting anymore.
I was able to connect from my phone to my laptop with SSH before, but not anymore. I also cannot connect from my laptop to other devices using SSH. My friend and I want me to get into his server using SSH, but when I try to connect to him, I receive the following as an output: ssh: connect to host port 22: No route to host
After receiving the error above, I tried to ping his network just to make sure it's working and received the following after pinging: Destination Host Unreachable
Is the issue on my side or does he need to do any configs on his side?
Any assistance would be appreciated!
Thank you for your time!
