GPG error, but could not update public key

When I ran:

sudo apt-get update

I got these errors:

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://cli.github.com/packages stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 23F3D4EA75716059
W: Failed to fetch https://cli.github.com/packages/dists/stable/InRelease  The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 23F3D4EA75716059
W: Some index files failed to download. They have been ignored, or old ones used instead.

So following other answers here, I tried to update the key using this:

sudo apt-key adv --recv-key --keyserver keyserver.ubuntu.com 23F3D4EA75716059

Which returned this:

Executing: /tmp/apt-key-gpghome.UZIznQa775/gpg.1.sh --recv-key --keyserver keyserver.ubuntu.com 23F3D4EA75716059
gpg: key 23F3D4EA75716059: public key "GitHub CLI <opensource+cli@github.com>" imported
gpg: Total number processed: 1
gpg:               imported: 1

But when I run "sudo apt-get update" again, I get the same errors (see above) again.

I'm pretty much a Linux newbie. Can anyone see what I'm doing wrong? Thanks.

What is the output of `cat /etc/apt/sources.list`

@Rishon JR See edited question with the output you requested.

Your sources look fine... There's something wrong with the key. Try `sudo apt-key del 23F3D4EA75716059 && sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-key C99B11DEB97541F0 && sudo apt-get update`

@Rishon JR Before I run your code, want to check the key in the second command, starts with C99B.... Shouldn't that key be the same as the one in the first command: starts with 23F3... ?

I looked it up again... and it's the correct key for ubuntu 20.04. (I would recommend upgrading to ubuntu 22.04 LTS using `sudo do-release-upgrade`). If you are not willing to upgrade, do `sudo apt-key del 23F3D4EA75716059 && sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-key C99B11DEB97541F0 && sudo apt-get update`

@RishonJR No luck. "apt-get update" returns exactly the same errors re NO_PUBKEY 23F3D4EA75716059. I would like to upgrade to 22.04 LTS but cannot; if I run do-upgrade-release, I get "Please install all available updates for your release before upgrading.".

Make a live USB and use that to upgrade (In the install options there will be upgrade ubuntu alongside reinstall ubuntu and other options as well).

Hi Rick, Any update?

@Rishon_JR Just saw this and I'll give it a try. Thanks for the suggestion. I'll let you know how it works.

@Rishon_JR. Sheesh, I've messed up. I created a LiveUSB with 22.04. Installed 22.04 but selected "Install along side 20.04" since I was afraid of messing up my current set up. But now I'm really messed up since none of my Home files and apps are available when I boot into 22.04. I should have realized this was happening when the install process forced me to create another partition (for 22.04). Can I unroll this somehow and install 22.04 on top of and in place of 20.04?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
