Hi,

I’m trying to ‘apt update’ and receive the following error. This is new, this has not been an issue for the life of my droplet (well over a year).

Reading package lists... Done
E: The repository 'https://repos.insights.digitalocean.com/apt/do-agent main Release' no longer has a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

I did use netstat to discover what appeared to be a Chinese IP address actively ssh’d into my box. I rebooted the box but still can’t connect to https://repos.insights.digitalocean.com - I can connect fine from home so this is localized to my droplet.

Was something potentially changed with my network configuration? Am I being MITM’d?

Thanks.
