How To Fix NO_PUBKEY 77B79B3FFAF7EF65?

I’ve been updating some of our droplets to 22.04 and came across this issue where it mentions: NO_PUBKEY 77B79B3FFAF7EF65. This occurs when I either try to apt update or do-release-upgrade.

I’ve tried some solutions like below and searched around, but realized that the key does not exist: sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 77B79B3FFAF7EF65

I assume sks-keyservers.net would’ve worked, but it’s down now and keyserver.ubuntu.com does not have the missing key 77B79B3FFAF7EF65.

Is there a quick solution to this? Since I’ll have to apply the method to multiple droplets.

I also stumbled across this issue when running a simple sudo apt-get update on a 20.04 droplet seems like 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.

I would appreciate some official DO guidance with the best way to update this across all my droplets

I’m experiencing the exact same issue. Can’t seem to be able to find a solution anywhere.

# sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 77B79B3FFAF7EF65
Executing: /tmp/apt-key-gpghome.zoN6XXCefP/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys 77B79B3FFAF7EF65
gpg: keyserver receive failed: No data

This is ill advised, but I do seem to have found a temporary workaround.

By editing this file:

sudo vim /etc/apt/sources.list.d/digitalocean-agent.list

From this:

deb https://repos.insights.digitalocean.com/apt/do-agent main main

To this:

deb [allow-insecure=yes] https://repos.insights.digitalocean.com/apt/do-agent main main

I was able to get around the issue.
