I am running 18.04LTS and am trying to get my system to download the 20.04 release. Running update-manager with no arguments is failing. It starts downloading the repository information, gets 90% done, then aborts with "Failed to download repository information. Check your internet connectiion."
I am able to ping, traceroute and http to www.ubuntu.com and archive.ubuntu.com with no problems. My internet connection is just fine for other destinations.
Now "apt update" is not working.
sudo apt update
