snapin bash

[fjunier]

Hello,

I’m a French teacher and I want to use Fog to deploy Ubuntu images on workstations in a school and I can’t manage to use a script/bash snapin.
The Ubuntu 22.04 image is deployed on my client machine and the Fog client is installed and working.
The file attached to my snapin contains this little script :

#!/bin/bash
sudo apt install geany

In the client log file I have the following trace:

 4/5/2024 5:08:34 PM Client-Info Client Version: 0.13.0

Attached is a screenshot of the creation of my snapin. Is the problem with my snapin settings, the client, a rights issue or something else?

Thanks in advance to anyone who can shed some light on this.

@fjunier Could you try this script:

#!/bin/bash
sudo apt-get -y --force-yes install geany && exit 0 || exit 1

[Tom Elliott]

Have you ried logging into the machine and just runnign the script as yourself?

Yes, the script runs on the machine. I also disabled password entry for the machine’s unique account because I thought that entering the password could cause problems.

@Tom-Elliott Thank you. I reinstalled with SmartInstaller.exe and now the snapins no longer run. I have the following error:

I will reinstall the client

@Tom-Elliott Thanks for the response. I I have click the button Reset Encryption Data and the authentification problem is solved, moreover mys snapin ran successfully. Cool !

[Tom Elliott]

@fjunier So i suspect the original script you had:

#!/bin/bash
sudo apt install geany

Was either the incorrect command (most times apt and apt-get are not the same things)

and/or it was waiting for confirmation from the end user.

I don’t know why it would run successfully when you ran the script locally, but maybe you would just “confirm” if it was requesting?

The methods I added :&& exit 0 || exit 1 were to ensure if the command completed successfully (the && part) to return with a code of 0 explicitely, while if the command failed, return with an exit code of 1 explicitely.

Hopefully this works properly for you.

The other pieces added after replacing apt with apt-get, was -y (confirm) and --force-yes (if interaction needed to confirm as well beyond the base install confirmation)

So should be more consistent.

@Tom-Elliott thanks for all !
