Unable to upgrade from 18.04 to 20.04


When I try to upgrade to from 18.04 to 20.04 I get a message saying that my Authentication has failed and the problem might be either with my internet connection (since I can connect to email, youtube, etc. the internet connection is OK) or a problem with the server. I assume that means the Ubuntu server. How can I troubleshoot a problem connecting to that server?

would be nice to give us some details about what did you try exactly (which commands, what was the response....)

More information: From Software Updates, I ensure 18.04 has all current updates applied. I then get a message that the new version, 20.04 is available with a button to "Upgrade." I hit "Upgrade" and I get a request to "Authenticate" my request with my password, which I enter, and I get a message box with links to "What's new in 20.04", Ubuntu questions, etc. and this message box has a button at the bottom to "Upgrade", which I hit and then I get the message that my authentication has failed with the two suggestions; either I don't have an Internet connection or the server is unavailable. I have a "test installation" of Ubuntu on my sda7 partition and I went through exactly the same steps that I just outlined. I did not run into any issues at all and successfully upgraded that version 18.04 to 20.04.

One thing just crossed my mind.

Is your 18.04 32 bits?
If so, you cannot upgrade directly.

If you are running x64, have you attempted to upgrade by running this command from the command line?

sudo sudo update-manager -c

Unable to upgrade from 18.04 to 20.04

Well, it's now the middle of Feb. and I'm no closer to upgrading my main system from 18.04 to 20.04 than I was about 3 months ago. From time to time I get a notification that version 20.04 is available, asking if I would like to upgrade. I try to upgrade and the upgrade stops in the same place as always. It appears the server, as in the server from which new versions are downloaded, is trying to install either version 14.04 or 16.04 and, therefore, fails. Does anyone have any thoughts about why this might be happening or how I can troubleshoot the problem.

1) Could there still be enabled some 14.04 or 16.04 repositories in your /etc/apt/sources.list? Actually, /etc/apt/sources.list and /etc/apt/sources.list.d/*.list are the first things I would check if a system upgrade failed. I usually disable any third-party repositories before attempting a system upgrade.

2) Try upgrading from the command line via do-release-upgrade. Even if not successful, it may give you some additional hints as to what went wrong.

Thank you for your response.
I tried installing from the command prompt and this is what I got;
root@vesalius:~# do-release-upgrade

Get:1 Upgrade tool signature [1,554 B]
Get:2 Upgrade tool [1,341 kB]

Authentication failed
Authenticating the upgrade failed. There may be a problem with the network or with the server.

Issuing the cat /etc/apt/sources.list command here's part of what I got;

I've searched for those two lines and cannot find them. Where would they reside?

Your /etc/apt/sources.list is incomplete. There should be more repositories enabled beyond partner. See this question on Ask Ubuntu.

Add these lines at the end of the file:
Code:
deb http://archive.ubuntu.com/ubuntu bionic main restricted
deb http://archive.ubuntu.com/ubuntu bionic-updates main restricted
deb http://archive.ubuntu.com/ubuntu bionic-security main restricted

First, thank you both for responding. I truly appreciate this. I'm not new to computers (hardware or software) and I'm not new to having Linux/Ubuntu on my PC BUT you need to treat me like an absolute beginner in regards to the innards of the OS. My knowledge and experience of operating systems is from 25 years ago on VMS (if anyone even knows that acronym any more).

shruggy; I don't understand what file I would add the the lines "deb http://archive..." etc.etc. to. Also, I looked at 'this question' on Ask Ubuntu and it appears others have had the a similar problem that I am but I was a bit lost regarding what they were doing to solve the problem.

Pentium4User; Listed below are the outputs from each of the commands.

Scrap this. The output in your post #11 above differs from what it was in #8. Looks like you omitted some parts of the output in #8. This makes my previous response irrelevant.

Instead, try
Code:
sudo apt-get install --reinstall ubuntu-keyring

shruggy; My apologies, I used ellipses to indicate that I had left some things out. I included only those lines that I thought were relevant.

pan64; I issued each command you listed and all seemed to work just fine with a couple of them indicating there were 4 packages that were automatically installed, were no longer needed and could be removed. Is it possible one of these 4 packages could be causing the problem? The actual do-release-upgrade command gave me the same error I've been getting anytime I try to upgrade. See below;
do-release-upgrade
