But the ps output already has identified a hang inside of iptables itself
hanging.
The commandline identified it coming from
767 # First install a test chain
768 (rc, out) = cmd([exe, '-N', chain])
769 if rc != 0:
In the example:
/sbin/iptables -N ufw-caps-testZNBjxu
That doesn't have a lot of content yet, it is "just" installing a new
chain.

Title:
autopkgtests get stuck in Eoan with iptables 1.8.3
Status in ufw package in Ubuntu:
New
Bug description:
Hi,
it is time to report a bug to keep all info in one place.
First of all ufw tests were broken with iptables 1.8.3 due to an ordering
issue in the output.
This I fixed and tested in [1].
It only adds one more "allowed result" to one of the tests, so it should be
no big change.
I double checked the upload to not (by any accident) change something else.

=> That seems safe to me.
But since this hit Eoan the tests get stuck and hang what seems until aborted
(we have seen up to 75h). A normal execution in the past was ~30 minutes.
The modified test worked fine: http://paste.ubuntu.com/p/RKFvhTP8Ft/
But the test for ufw has multiple runs and I only fixed/modified/tested the
"root-unitest". I'm running the full test now hoping it might reproduce locally
for debugging.
First I thought something else in Eoan changed now trigging this issue. But
that is rather unlikely, as without the new iptables it works fine.
So for now the working theory for now is that iptables 1.8.3 changed
something else changed
Formerly this was not seen as it failed on the bug I fixed before hitting the
hang.
But with the fix above applied it now triggers the hang.
It always hangs at this tests:
Test get_netfilter_capabilities()
ERROR (CommandError): No server with a name or ID of
'0eb6260d-c544-41eb-8cfa-baa9a745c528'
nova show 0eb6260d-c544-41eb-8cfa-baa9a745c528
(adt-eoan-s390x-ufw-20190815-202934)
The test uses no Nova, the last two lines is from the automation being
aborted.
What is interesting is that this test would be ran up to three times,
and it sometimes succeeds one or two times now. So it might (in
addition to be broken) also be flaky.
