apt update - BADSIG 871920D1991BC93C

I have an ansible script that runs each weekend which basically does an apt update && apt upgrade -Y on every Debian based instance. This weekend it failed on one Ubuntu host. When I went it to try it manually, this was the output:

Solved

The first google result mentions apt-cache - which I also run , so a first level debug step is to delete the /etc/apt/apt.conf.d/00aptproxy file that redirects apt requests to the cache I run in an LXC container. After that, if I re-run the apt update it works perfectly. Seems like a problem with the cache then. I’m not sure why it would only affect this host though - I have other Ubuntu VM’s in the fleet that are not getting the original error.

How to deploy a Node.js app

This is one of those things that is simple once you know it. I had my tiny Node service working on my MacBook, but how do I run it on the server?

Native or Container

Obviously I need Node.js installed on the server, should I have it in a Docker container, or native on the machine. There’s no clear answer here - in a container set up with Docker Compose might be more in line with my ideology of treating machines as disposable, but a native install is simpler, and I probably want to make life simpler at this stage when I’m learning everything.

Proxmox - Installing a Virtual Machine

Tue, 07 Feb 2023 00:00:00 +0000

Installing your first virtual machine (VM) in the Proxmox hypervisor is pretty straightforward. This post runs through those steps using Proxmox 7.3.

You need an operating system for your virtual machine, I’m going to use Ubuntu server in this example, but it could just as easily be Windows server , or regular windows, or one of the desktop Linux distributions. Whichever you decide, you’ll need to find and download the ISO for it. The ISO is a (usually quite large) file needed to install the operating system.
