    Tried to Upgrade from Software Updater; wanted me to Refresh the data base repository. That Errored, but I was unable to copy it to send it. I closed that window and the Upgrade came up which I started. It Errored loading file 151 of 195.

    If you did from a terminal... an apt cache refresh is
    Code:
    sudo apt-get update
    The do
    Code:
    sudo do-release-upgrade -d

    Did everything again. The Upgrade came up which I started. It Errored loading file 151 of 195. My laptop did the same thing loading file 207 of 214.

    I have a screen shot of the errors from the refresh. How do I get a screen shot to the forum that ends in .png?

    There should be a section that says "Manage Attachments" on the reply screen. You can attach files there and then add them to your post.

    It's pretty strange to get this error unless you are missing the public key to validate the package index.

    Are you able to run this command and post the output?

    Code:
    apt-key list
    I ran this on a 18.04 machine that I have running and this is what it says for that key. Check if you have something similar.

    Code:
    /etc/apt/trusted.gpg.d/ubuntu-keyring-2012-archive.gpg
    ------------------------------------------------------
    pub   rsa4096 2012-05-11 [SC]

    Re: 21.04 Upgrade Will Not Install

    Now we are getting somewhere...

    If from CharlesA's post, if that key is not there (which it does say it was missing), then you can add it via:
    Code:
    sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys  3B4FE6ACC0B21F32
    Please verify that is the key it says in your error. Just to make sure I didn't typo that...

    Then verify it received it in the keyring
    Code:
    apt-key list
    And yes, that is very weird that, what should be a default public key is missing???

    Re: 21.04 Upgrade Will Not Install

    The advice on #27 and the Entry on #28 Solved the issue; both the PC and the Laptop installed 21.04 without a burp. I will show this thread SOLVED. Thank you to all who helped.
