  5. # Due to reasons [1], the old python2 matrix-synapse package will not stop the
  6. # service when the package is uninstalled. Our maintainer scripts will do the
  7. # right thing in terms of ensuring the service is enabled and unmasked, but
  8. # then do a `systemctl start matrix-synapse`, which of course does nothing -
  9. # leaving the old (py2) service running.

  11. # There should normally be no reason for the service to be running during our
  12. # preinst, so we assume that if it *is* running, it's due to that situation,
  13. # and stop it.
