[bitfolk] URGENT: Ubuntu 22.04 customers risk config reset at reboot

Hi, After a recent update of the cloud-init package on Ubuntu 22.04 something appears to be going wrong and cloud-init is being run at every boot - WHICH WILL LEAD TO YOUR NETWORKING CONFIG BEING DELETED. In addition, the password of the "ubuntu" user is locked and the SSH host keys are regenerated. I do not yet know whether this is the result of some misuse of cloud-init on our part, or some bug in cloud-init. The outcome is so bad that I have to warn you about this as soon as possible, before I've fully understood the issue. It is safe — and at this stage recommended — to simply remove the cloud-init package which serves no purpose at BitFolk after first boot. $ sudo apt remove cloud-init If it is too late for you and you already did reboot and are now wondering why your VM has no network and is trying to DHCP for one, here's how to fix things. 1. Connect to your Xen Shell with ssh accountname(a)accountname.console.bitfolk.com More info: https://tools.bitfolk.com/wiki/Xen_Shell 1. Work out how you're going to get root access from a console log in prompt. If you have a user other than the initial "ubuntu" one, you'll use that. If you don't, you'll need to reset the password for "ubuntu" as it has now been locked. If you have a login already, use "console" command and log in to your VM at its console. If you need to reset the "ubuntu" password: a) Make sure VM is shut down xen shell> shutdown b) Follow these instructions substituting "ubuntu" for "root": https://tools.bitfolk.com/wiki/Resetting_root_password then "boot" your VM again and log in as "ubuntu". 2. At this point you're logged in as "ubuntu" on a VM with no network. Put /etc/netplan/50-cloud-init.yaml back to how it was. Here is an example file: https://tools.bitfolk.com/wiki/Ubuntu#Migrate_to_netplan The "gateway" statements are deprecated but will still work. Make sure to "chmod go= /etc/netplan/50-cloud-init.yaml" so it has correct permissions $ sudo netplan generate $ sudo netplan apply Your networking should now work again 3. sudo apt remove cloud-init It will now be safe to reboot in future. As I say I am still looking into where the problem lies here and the best way to fix it. The example netplan config linked above has some deprecated statements in it which I will also fix (if it doesn't have "gateway4" etc in it any more then I did already by the time you read this), but it does (still) work.
