And 1.2.0 is not released yet.  Based on the related comments in /usr/lib/
python3/dist-packages/helpers.py, there is a known incompatibility, so we 
shouldn't just comment that constraint out.

Unfortunately, reverting msgpack isn't really an option either since that 
would break python-pip.

I suspect the most viable option is to temporarily have borgbackup use the 
bundled msgpack until it can be upgraded to 1.2.0.

If an NMU would help, I can do it.

Bug#953989: borgbackup reports installed python3-msgpack is incompatible

[Gordon Ball]

Package: borgbackup
Version: 1.1.11-2
Severity: grave
Justification: renders package unusable

After updating python3-msgpack from 0.5.6-3 -> 0.6.2-1, attempting to
run any borg command fails with the following message, making borg
wholly unusable.

$ borg -v
You do not have a supported msgpack[-python] version installed. Terminating.
This should never happen as specific, supported versions are required by our 
setup.py.
Do not contact borgbackup support about this.

The setup.py in question requires <= 0.5.6 (plus some exclusions). It
looks like borgbackup 1.2.0 declares support for this msgpack version.
