SCCM (ConfigMgr) - SHA-2/256 is NOT supported on this platform | Unix/Linux Systems

It's a new error for me.
It happened in a Solaris 10, and i got stuck for a while to troubleshoot and solve - fortunately i've got some nix skills from earlier professional experiences, the same way i've got google search skills.

So, if you came up with the error message in your (/var/opt/microsoft/scxcm.log) :

"SHA-2/256 is NOT supported on this platform"


You need to do this :
(as root)
cd /opt/microsoft/configmgr/bin
./uninstall

cd ../../
rm -Rf configmgr

Now, re-install your agent with the '-ignoreSHA256validation' parameter :

./install -mp CCM_MP_SERVER -sitecode SITE_CODE -ignoreSHA256validation -nostart ccm-Sol10sparc.tar


(you might need to replace 'ccm-Sol10sparc.tar' to your correct package)


cd /opt/microsoft/configmgr/bin
./ccmexecd start

So, if you go to your SCCM console, your new device will show up correctly.
