Hello, I’ve been handed the new requirement of updating all our virtual machines to ubuntu 22.04 lts. I’m trying to create a new k8s cluster via rancher/vSphere like normal, but I can’t get my ubuntu 22 template to provision. I’ve gotten past quite a few hurdles with it, and it’s really close, but is now failing here:

2022/05/18 14:43:19 [INFO] [node-controller-rancher-machine] Docker is up and running!

I’ve googled around, and I can’t find much about this error, so I’m hoping someone can help me out, thanks in advance.

how did you make the 22.04 template you're cloning from? it reads like cloud-init isn't running and the ssh connection isn't being established because the user/key wasn't injected on the downstream node

I originally had the

waiting for ssh to become available

issue, but I got past that by adding this line to `/etc/cloud/cloud.cfg.d/99-installer.cfg`:

datasource_list: [ "NoCloud", "VMwareGuestInfo" ]

And I ran these commands as suggested by a bug report I found on github:

rm -fr /var/lib/cloud/instances/
rm -fr /var/lib/cloud/instance 
rm -f /etc/machine-id /var/lib/dbus/machine-id
truncate -s 0 /etc/machine-id
ln -s /etc/machine-id /var/lib/dbus/machine-id

boom!

Thanks, and thanks for the help. Yeah probably time to upgrade the encryption. I’m not on the newest rancher version, so I haven’t looked to see if that’s something that has already been fixed.
