Hard times upgrading ubuntu 20.04 to 22.04

 Recently, I decided to do a reinstall of Ubuntu 20.04 on my home computer.  This is what it came shipped with.  The overall process was a breeze, as Dell has made factory re installs a snap (no pun intended).  However, I ran into issues when attempting to upgrade Ubuntu 20.04 to Ubuntu 22.04. 

I kept getting the following error whenever I attempted to run 

scott@scott-Precision-3650-Tower:~$ sudo do-release-upgrade
Checking for a new Ubuntu release
Failed to connect to https://changelogs.ubuntu.com/meta-release. Check your Internet connection or proxy settings
No new release found.

I then checked into the firewall on my system, and made sure 1022/TCP was open, per many posts on the web.  Still no go.  

Luckily, I found a post from Reddit user PhoenixOneThree who mentioned that adding the following lines to your /usr/lib/python3/dist-packages/UpdateManager/Core/MetaRelease.py file would allow the upgrade to run.  

import ssl
ssl._create_default_https_context = ssl._create_unverified_context

Once I added the lines to my MetaRelease.py file, it allowed the upgrade to take place.

The install went off without a hitch.  Now, I will admit that since I don't know the full effects of adding the line to the MetaRelease.py file, once the upgrade was complete, I checked the MetaRelease.py file, the import ssl entries were removed.
