Trellis on M1 Pro: vm start (Failed to connect to the host via ssh)

trellis
1

Hey all :slight_smile: I’d appreciate some help getting started. I’m new to Trellis and trying to get the local dev environment working on my M1 Pro.

I’m using the lima setup, seen as Vagrant requires Parallels on apple silicon and I don’t want to use that if I don’t have to! So I have python 3.9.6, limactl version 0.20.1, and trellis 1.11.1. Here’s the steps I’m taking:

  1. trellis new domain.com
  2. cd domain.com
  3. trellis init
  4. trellis vm start

At this point I get this error:

PLAY [WordPress Server: Install LEMP Stack with PHP and MariaDB MySQL] *********

TASK [Gathering Facts] *********************************************************
[WARNING]: Unhandled error in Python interpreter discovery for host default:
Failed to connect to the host via ssh: username@127.0.0.1: Permission denied
(publickey).
fatal: [default]: UNREACHABLE! => {"changed": false, "msg": "Data could not be sent to remote host \"127.0.0.1\". Make sure this host can be reached over ssh: username@127.0.0.1: Permission denied (publickey).\r\n", "unreachable": true}

I’m not sure what I’m doing wrong, nor what the problem is. Any assistance would be greatly appreciated.

Thanks!

@Jack_Kudla - I see you posted asking if I Had fixed it, but have now deleted the post. I was unable to fix it. Have you managed to figure it out?

Generate new key add to keychain, cleared hosts and deleted the vm started a new one

5

Were you able to get it working?

Since I upgraded from Intel to M3 Pro/macOS 14.4.1 I also had a lot of issues (both with lima and parallels, which is another topic).

I found out that you need to disable the firewall to get it working properly.
My steps to reproduce, even though I am not sure you have the same problem.

Start VM (failing)

trellis vm start failed with Could not determine IP address for VM instance: no IP address could be matched in the ip route output.

Error starting VM.
Could not determine IP address for VM instance: no IP address could be matched in the ip route output

I could access the vm via limactl shell example, but i could not access it in the browser.

I noticed that /etc/hosts was not updated.
I used trellis vm sudoers | sudo tee /etc/sudoers.d/trellis, but it did not change anything.

Manually edited /etc/hosts

So, I added the entry myself:

127.0.0.1 example.test www.example.test

Provision

Then, I ran trellis provision development.
Now I can access the site via the browser.

Disable firewall

This issue helped a lot:

I disabled my firewall, now the output is the following:

Updating /etc/hosts file (sudo may be required, see `trellis vm sudoers` for more details)

Your Trellis VM is ready to use!

* Composer and WP-CLI commands need to be run on the virtual machine for any post-provision modifications.
* You can SSH into the machine with 'trellis vm shell'
* Then navigate to your WordPress sites at '/srv/www'

The /etc/hosts file was updated automatically:

## trellis-start-example
192.168.106.2 example.test www.example.test
## trellis-end-example

Note the different IP address. 127.0.0.1 was working for me, at least sometimes :smiley:
I deleted my manual entry.
