I noticed that back on October 3, 2019 Microsoft snuck in a blurb on the DSC documentation page saying that DSC and OMS for Linux should not be used together on the same VM: https://github.com/MicrosoftDocs/azure-docs/commit/e58260ef8bf5ab8ffee8d9a1d95b5031cf20c129#diff-e4f18cdc8e305fd463a5813fdc3b199b

Given how long it has been since this issue was reported, I’m wondering is DSC even maintained anymore?

The issue is that the DSCForLinux extension install version 1.1.1-294 of the dsc package, this version cause omiagent to segfault. Installing version 1.1.1-926 fixes the issue.

All those cases are related to this issue:

I have already submitted a fix to bump up the version of the dsc package:

Bump up dsc package version

I am following up with PG internally for them to merge and push the fix:

Meanwhile you can fix the issue by installing the package manually:

wget https://github.com/microsoft/PowerShell-DSC-for-Linux/releases/download/v1.1.1-926/dsc-1.1.1-926.ssl_098.x64.rpm
yum upgrade dsc-1.1.1-926.ssl_098.x64.rpm -y

I hope this helps.
