]: [DNF fails to resolve dependencies]

Issue: php-composer(symfony/debug) version >= 3.4 and < 4 is not available
Resolution: If symfony/debug is a runtime dependency, the package needs to be adapted to run with available dependency, or missing dependency be added, or packaged retired.

If symfony/debug is a buildtime dependency, only used byt the test suite, the test suite needs to be adapted of relevant unit tests ignored.
