Hi,

I ran into this problem today also. I do not know what changed that necessitated this, but this resolved it for me:

wget -qO- https://repos-droplet.digitalocean.com/install.sh | sudo bash

Several other methods of adding the key did not work. For whatever reason, only the above did.

Thanks, Vishnu

Same problem. Did you/anyone get an answer? Support is impossible to reach which I find disappointing. The last time I needed support was perhaps a few years ago and I do not recall it being unavailable or buried so deep to have made the search cost so high that I gave up trying to find out how to get Digitalocean to unbreak our servers.

EDIT: I just saw the thread. It is solved, but nevertheless annoying/disappointing/dissatisfying. I am particularly annoyed at the impossibility of even asking Digitalocean staff for support. Cannot create a support ticket without logging in, cannot log in because there is no password, cannot get password - perhaps only available if I pay them for support to not break my servers. Insane.

To fix this I had to fully remove and re-install the digital ocean agent, which meant:

  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
