Question

Is Ubuntu 20.04 LTS no longer supported?

I’m getting the following The repository ... no longer has a Release file. error on many of my Ubuntu 20.04 LTS droplets. Is this OS no longer supported? If it is supported, how do I resolve this?

I can happily edit /etc/apt/sources.list to whatever it needs to be… but I’ve never had to do this with within-5-years-released Ubuntu LTS versions before.

Hey @johnnyutahh,

Ubuntu 20.04 LTS is still supported however, I’ll recommend upgrading to Ubuntu 22.04 LTS.

As for the error you are receiving, you can just disable the repository if you don’t need it from your /etc/apt/sources.list file.

Additionally, you can try running the following

  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

It appears I’m forced to install the DigitalOcean “metrics agent” – something I never installed and do not want – on my system in order to fix this with curl -sSL https://repos.insights.digitalocean.com/install.sh | sudo bash. (“Uninstalling” with apt-get purge do-agent did not solve my problem.) Details:

https://docs.digitalocean.com/products/monitoring/quickstart/#install-the-metrics-agent-on-existing-droplets

So to be clear: something I do not want and never installed on my system is causing Ubuntu-apt-update errors. Now I’m forced to update all my automated deployment scripts only to accomodate this DO strangeness.

Is there some other way for me to interpret this? If so, what can be done to avoid this problem in the future?

For now: This is unacceptable. The previously-stellar-DO reputation has lost it’s “luster” with me. If this is what DO has become, I no longer want to be a customer and plan to move to another hosting service as soon as I can.

With regards to the Certificate verification failed: error:

The following solution below does -not- solve my problem. (I already had ca-certificates package installed.)
