From what I can read, to enable VM Insights the Dependency Agent for Linux is required. When attempting to install it, however, I get the following error.
(VMExtensionHandlerNonTransientError) The handler for VM extension type 'Microsoft.Azure.Monitoring.DependencyAgent.DependencyAgentLinux' has reported terminal failure for VM extension 'DependencyAgentLinux' with error message: '[ExtensionOperationError] Non-zero exit code: 90, /var/lib/waagent/Microsoft.Azure.Monitoring.DependencyAgent.DependencyAgentLinux-9.10.14.20760/bin/time-limit 870 scripts/install.sh >/dev/null

Is the 5.15.0-1014-azure kernel not supported?
It seems 5.8 and 5.4 are the only kernels supported for Ubuntu 20.04 from https://learn.microsoft.com/en-us/azure/azure-monitor/agents/agents-overview#supported-operating-systems
Are there any solutions to enable VM Insights on Ubuntu 20.04?
Thank you for any help.

Same issue.... but was able to enable it on a different VM (same OS) earlier in the week so seems like a new issue

@Lawrence Dwight @Anonymous @Anonymous @Ash Skelton Only 5.8 and 5.4 Kernels are supported for Ubuntu 20.04 OS. To know the list of kernels supported for any operating system, refer this document.
Thanks, this is somewhat helpful. I guess the part I am not clear on - who has pushed 5.15 "azure" kernel? Is this something Ubuntu have done or Microsoft? It just seems to be handled poorly. If someone goes and creates a new Ubuntu VM today they are going to get a kernel not compatible with Azure related features. And as far as I know they have no say in this i.e. I don't think you can select kernel version when you create a VM so a version is forced that fundamental features do not support.
So either:
This just feels like a headache that could be avoided.
Thanks
@Anonymous Thanks for providing further information. I will check on this with product team and provide you an answer.
@SwathiDhanwada-MSFT please provide an update on this problem - its been a month and neither a reply from you nor the situation has been fixed
Seems to be latest kernel, downgraded kernel and then installs ok. Went from 5.15.0-1014-azure to 5.4.0-1025-azure as a test and dependency agent then installed fine.
