Package: matrix-synapse
Version: 0.34.1.1-1
Severity: |grave|


After upgrading the package matrix-synapse is unable to start.

This is what I see in the log (journalctl -xe):

Jan 16 07:03:12 foo python3[3896]: ERROR:root:Needed pymacaroons-pynacl>=0.9.3 but it was not installed
Jan 16 07:03:12 foo python3[3896]: ERROR:root:Needed msgpack-python>=0.4.2 but it was not installed
Jan 16 07:03:12 foo python3[3896]: ERROR:root:Needed prometheus_client>=0.0.18,<0.4.0, got prometheus-client==0.5.0
Jan 16 07:03:12 foo python3[3896]: Missing Requirements: python3-pymacaroons-pynacl>=0.9.3, python3-msgpack-python>=0.4.2, python3-prometheus_client>=0.0.18,<0.4.0
Jan 16 07:03:12 foo python3[3896]: To install run:
Jan 16 07:03:12 foo python3[3896]:     sudo apt install python3-pymacaroons-pynacl>=0.9.3 python3-msgpack-python>=0.4.2 python3-prometheus_client>=0.0.18,<0.4.0
Jan 16 07:03:12 foo systemd[1]: matrix-synapse.service: Control process exited, code=exited, status=1/FAILURE



Looking at one of the packages:

$ apt-cache policy python3-prometheus-client 

python3-prometheus-client:
  Installed: 0.5.0+1-1
  Candidate: 0.5.0+1-1
  Version table:
 *** 0.5.0+1-1 500
        400 http://ftp.ee.debian.org/debian unstable/main amd64 Packages
        500 http://ftp.ee.debian.org/debian testing/main amd64 Packages
        100 /var/lib/dpkg/status
     0.0.18-1 500
        500 http://ftp.ee.debian.org/debian stretch/main amd64 Packages


So matrix-synapse requires a version that is not in debian repos, and the package
does not seem to restrict the version, so it resulted in broken matrix instance after upgrade.
