 This is a bug in TAU Commander.
 Please send '/home/runner/.local/taucmdr/debug_log' to 
     <support@paratools.com> for assistance.

It appears that TAU Commander is attempting to build a TAU configuration which uses Intel level0 support, and is attempting to download level0. TAU Commander should not attempt to download level0 if it is not available, as this is part of Intel oneAPI and not something we can manage ourselves. Also, a build of TAU using level0 should not be done in an environment like the testing environment where level0 is not already installed.
