This is an informational post:
I got the following error while trying to debug under Ubuntu:
"SiAgent launched but did not report its status. Please check your installation."
When trying to do a "Bare run" got SiAgentARM error 127
This was because "siagentarm" depends on libQtNetwork.so.4 which is not installed by default, since 18.04 installs libqtnetwork5.
sudo apt install libqt4-network
Thank you for posting this solution in an easy to find format. I know the information is also provided in some older forum posts but it can be hard to find.
