The extension install fails because no unversioned python command is installed on the image:

# /usr/bin/env python --version
/usr/bin/env: ‘python’: No such file or directory

I recommend you install python 2.7 using the command below as I have seen some issues with some extensions and python 3.6:


sudo yum install python2 -y
sudo alternatives --set python /usr/bin/python2

@johanburati thanks for your input! I've noted elsewhere but we are working on a fix/strategy going forward for RHEL/etc new distros that are not proving python by default.

Thank you for your submission. As previously announced, the Log Analytics agent has been deprecated and has no support as of August 31, 2024. If you use the Log Analytics agent to ingest data to Azure Monitor, migrate now to the new Azure Monitor agent. As part of deprecation, open issues and pull requests will be closed.
