[BUG]: VM extension TeamServicesAgentLinux fails with "AttributeError: module 'importlib' has no attribute 'load_source'" #5012
Comments
We've rolled back extension to previous version (1.23), I am looking into the root cause. |
Is the rollback still applied? I am still getting the same issue with my Ubuntu 24.04 LTS VMSS created 3 days ago which apparently uses the agent version 1.25.2.0.
|
Same here. A VMSS based on an Image I've just created from the same Ubuntu 24.04 template.
|
I'm trying to create a new VMSS using Ubuntu 24.04 and had exactly the same problem. |
A workaround until this is fixed can be using a VMSS with Ubuntu 22.04. It's important to delete the agent pool and 24.04 VMSS and set up everything from scratch. With 22.04 it's working fine for me. |
There's something wrong that's still depending on Python 2 in the AzureRM.py. It seems to be some regression from this fix #3156 I added a script to reinstall python2 and then it worked extensionProfile: {

What happened?
I've created a VMSS in Azure using the latest Ubuntu 24.04 LTS image ("server" sku).
ADO Agents fail to start with AttributeError: module 'importlib' has no attribute 'load_source'
I tried SSH'ing into a VM instance, and managed to obtain the full error by running handler.sh manually, and I have attached the output below.
Agents seem to work fine rolling back to 22.04.
22.04 python version: 3.10.12
24.04 python version: 3.12.3
