Question

Jitsi 1-click droplet - how to upgrade Ubuntu?

Logged in to terminal some time ago and I was persistently offered the option to do-release-upgrade, obviously to Ubuntu 22.04LTS. I wasn’t in a rush, so it is only now that I am trying to do the upgrade. And it won’t!

apt update and apt upgrade both fault that some public keys are not available. For example:

=start=quote=
W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://repos.insights.digitalocean.com/apt/do-agent main InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 77B79B3FFAF7EF65
W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://repos-droplet.digitalocean.com/apt/droplet-agent main InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 35696F43FC7DB4C2
W: Failed to fetch https://repos.insights.digitalocean.com/apt/do-agent/dists/main/InRelease  The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 77B79B3FFAF7EF65
W: Failed to fetch https://repos-droplet.digitalocean.com/apt/droplet-agent/dists/main/InRelease  The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 35696F43FC7DB4C2
W: Some index files failed to download. They have been ignored, or old ones used instead.
=end=quote=

apt dist-upgrade resolved some of the package held back issues but still the no public key remains as shown in the quote above

Oh dear! Although apt upgrade and apt dist-upgrade has done all they can, it clearly isn’t enough because do-release-upgrade then responds:

=start=quote= Checking for a new Ubuntu release Please install all available updates for your release before upgrading. =end=quote=

Any ideas on how to progress would be welcome.

Thanks in advance.

Hey @jeffdeacon,

The same has been experienced here, https://www.digitalocean.com/community/questions/how-to-fix-no_pubkey-77b79b3ffaf7ef65?comment=192177

Basically, you need to update the keys. There are a couple of ways to go about the problem. DO updated the do-agent apt gpg key on the 5th december. you can see the new one here: https://repos.insights.digitalocean.com/sonar-agent.asc and the old one they have as a backup: https://repos.insights.digitalocean.com/sonar-agent.asc.bkup

i solved this with:

wget -qO - https://repos.insights.digitalocean.com/sonar-agent.asc | sudo apt-key add -

its worth noting apt-key add is depreciated but its a simple one-liner.

Another way to go about this is to follow these steps:

  1. sudo dpkg --configure -a
  2. sudo apt-get remove droplet-agent
  3. sudo rm /etc/apt/sources.list.d/droplet-agent.list
  4. sudo apt-get update
  5. wget -qO- https://repos-droplet.digitalocean.com/install.sh | sudo bash
