 You can easily correct the problem by executing `./bin/installdependencies.sh`.  
 The `installdependencies.sh` script should install all required dependencies on all supported Linux versions  
 > Note: The `installdependencies.sh` script will try to use the default package management mechanism on your Linux flavor (ex. `yum`/`apt-get`/`apt`).
-> For Fedora-based systems, the script automatically handles lttng-ust version compatibility by creating symlinks when needed (e.g., Fedora 41 ships with liblttng-ust.so.1 but the runner needs liblttng-ust.so.0).
