Bug description:
[Impact]
* Designate logs stack traces as per the original description:
dns.query.xfr() w/ timeout=not None and lifetime=None (default):
`TypeError: '>' not supported between instances of 'float' and 'NoneType'`
* Backport will improve the robustness of Designate on Ubuntu.
[Test Case]
* Synthetic reproducer for dnspython alone in comment #11.
* See below for OpenStack Designate included:
### Scenario ###
1) Start remote BIND
Use some external host as a DNS server to tor AXFR the Zone from.
Note: BIND9 on RHEL is provided in attached doc.
2) From your setup check that AXFR is possible
dig @10.9.95.132 debuntu.foo axfr
3) Create a Secondary zone with:
openstack zone create debuntu.foo. --type SECONDARY --master 10.9.95.132
### Expected result ###
Secondary zone is created and ACTIVE
### Actual Result ###
Secondary zone gets into the ERROR statuses + Error in log

Ok, so this is a bug in the "dnspython" library designate uses.
Version 1.16 which you had installed has:
if mexpiration is None or mexpiration > expiration:
mexpiration = expiration
Which is broken.
Version 2.0.0rc1 has:
(https://github.com/rthalley/dnspython/blob/v2.0.0rc1/dns/query.py#L925)
if mexpiration is None or \
(expiration is not None and mexpiration > expiration):
mexpiration = expiration
Which works.
[Where problems could occur]
* This small patch improves the robustness of python library code.
Issues should be self evident in errors logged.
[Other Info]
* Jammy+ have the fix. Focal/Bionic don't have it.
