I'm following this guide and I'm running into issues. https://www.tecmint.com/initial-ubuntu-server-setup-guide/

I am trying to create a linux machine in Ubuntu in wsl2 and then rename it using hostnamectl but have the error

Failed to create bus connection: No such file or directory

I have tried to follow these solutions.

This solution suggested installing a package which I did. How do I fix my problem with hostnamectl command. It cannot connect to dbus

xuhu55@LAPTOP-DUPSMABG:/usr/share$ sudo dpkg -l | grep dbus

This other solution involved using strace which unfortunately showed that my problem was not a symlink problem that the other solution could have solved.

hostnamectl shows error: "Failed to create bus connection: No such file or directory"

At the core, the problem is that hostnamectl is a systemd utility, which acts on the systemd-hostnamed.service. WSL doesn't currently provide support for systemd.

Also, WSL sets the hostname to the name of the Windows computer hosting the instance. While you can change it by changing the Windows hostname (Control Panel -> System -> See the name of this computer -> Change Settings), you can't change the WSL hostname itself.

What's your ultimate goal with changing the hostname, other than just following the tutorial you linked? Perhaps there is a better solution (e.g. changing the prompt).

  • I actually came to the tutorial I linked from another pluralsight tutorial on setting up kubernetes. Since pluralsight is blocked by a paywall, I'll list out what I'm supposed to run. # 1. 3 VMs Ubuntu 16.04.5 or 18.04.1.0, 1 master, 3 nodes. # 2. Static IPs on individual VMs # 3. /etc/hosts hosts file includes name to IP mappings for VMs # 4. Swap is disabled # 5. Take snapshots prior to installations, this way you can install # and revert to snapshot if needed ssh aen@c1-master1 Dec 24 '20 at 19:18
  • I think you are going to find it difficult to complete that Kubernetes tutorial using WSL2. WSL2 instances run as a NAT'd VM behind a virtual NIC that Windows provides, and that NIC address changes on every restart (and you can't control it easily). I'd probably recommend using something like VirtualBox instead, where you have more control over the network. If you have Windows 10 Professional or higher, you could also use Hyper-V (which is actually what WSL2 uses behind-the-scenes) to give you more control. Dec 24 '20 at 19:58
  • I actually have access to both VirtualBox and Hyper -V as well as another tutorial tailed just for WSL2. kubernetes.io/blog/2020/05/21/… I'll try to go down the Hyper-V path for now and hopefully it will permit use of things like hostnamectl Dec 24 '20 at 20:24
