Thanks. You can see I made changes to our CI in this PR, and I managed to enable lldb, enable python testing and everything, but everything still passes in the lldb test suite.

This is a linux system, too it should be capable to reproduce this, right?

Can you help get this CI up to reproducing this problem?
