           Summary: python-systemd: Incompatibility with Python 3.x UUID
                    class
        QA Contact: systemd-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: gandro at gmx.net
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: general
           Product: systemd

Using the UUID class in the systemd.journal module in Python 3.x causes an
AttributeError. The problem seems to be that the python-systemd wrapper is
using
the undocumented UUID.get_hex() method. This undocumented, private method is
present in Python 2.7, but not in Python 3.x.

The documented way to retrieve the hex string is the UUID.hex attribute:
See: https://docs.python.org/3/library/uuid.html#uuid.UUID.hex

systemd version: 212

Relevant python tracebacks:
