Bug report

I have compiled hyperion from sources on a fresh fedora server image in a VM to fix a libcec bug. On start of hyperion I receive the following error log:

Was it compiled via Docker or native?

There seems to be a problem with the python modules on Fedora. Since you have compiled on this system anyway, you can solve the problem by deleting the python folder in the hyperion directory.

sudo rm -R /usr/local/share/hyperion/lib/python

This workaround worked. Wunderbar, danke!

Du kannst auch gerne noch ein PR erstellen, das den Usern hilft Hyperion unter Fedora zu kompilieren (CompileHowto.md).
Vielen dank.
