** Description changed: [Impact] Because of this bug upstream https://github.com/svinota/pyroute2/issues/923, in the versions of pyroute2 prior to 0.6.10, all delete operations (address, link, route, ...) fail with 'Operation not supported'. This is related to the kernel commit https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a6cec0bcd34264be8887791594be793b3f12719f Pyroute package has to be upgraded to a version 0.6.10 or later as long as the distro comes with the kernel that contains the above commit.
