Tried following docs [here](https://docs.inductiveautomation.com/display/DOC81/Command+Line+Installations), and it still prompts me for a username. What did I miss? ```auto ubuntu@dev-ignition1:~$ sudo ./ignition-8.1.1-linux-x64-installer.run -- "unattended=text" "user=ignition" Verifying archive integrity... 100% MD5 checksums are OK. All good. Uncompressing IgnitionInstaller 100% Root detected. Please enter a username to install Ignition as: Username: ``` Also tried with `textMode=true` appended onto the end and got the same behavior. ---

Hmm. Does the “ubuntu” user happen to have uid=0? Try ```auto cut -d: -f1,3 /etc/passwd ``` ---

Nope. UID=1000 GID=1000. But I ran it under `sudo` so the effective UID was 0. And the UID of the ignition user is 1001. It’s a normal user account and not a system account. ---

This is a nearly pristine install of the most recent Ubuntu 18.04 AMI on an AWS EC2 if you want to try it yourself. ---

Try without `sudo`, which is what generates the username prompt. ---

It worked without sudo. I’m assuming it does sudo (or some equivalent) internally in the script as needed? It also didn’t stop to ask me for a sudo password since the `ubuntu` account was setup to not need one. Would it have prompted me if one was? ---

yes it would have prompted if it was required ---

Has anyone experience with unattended _remote_ installation using tools like Ansible? I’m trying to get it to work, but the installation hangs either on the input for SU rights or if I run it with SUDO, it comes up with the above mentioned prompt… Is using the zip-install and the ignition.sh-file the only possible way? ---

Yes. You just need to have your script sudo to a _non-root user that has unprompted sudo privileges_ to do the install, e.g. on AWS Ubuntu instances, there is a user named “ubuntu” setup the right way: ```auto sudo -u ubuntu ./ignition-8.1.1-linux-x64-installer.run -- "unattended=text" "user=ignition" ``` If you don’t already have an account setup for sudo w/o password, you may need to make one first. Roundabout, but workable.
