From this post: https://kb.parallels.com/120327 I am supposed to use the latest Fedora OS for use with Parallel toolbox Version 17.1.6 (51584) which I have: Fedora 38, kernel 6.2.11-300.f38.x86_64 Yet Toolbox fails...here is the log attached

my guess is the author of this code was careless and failed to remove 'rc' which is causing the issue.
