[Bug 2004658] [NEW] autopkgtest fails because mailman3 takes too long to start

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Olivier Gayot (ogayot):

The autopkgtest test suite for mailman3 is often failing on Ubuntu
because the service takes too long to start.

What the mailman3-api test does is it restarts the mailman3 service
(using a legacy systemV command) and then tries to connect to it using
curl after 10 seconds.

```
service mailman3 restart
# wait for mailman3 to come back after restart
sleep 10
curl -s --user "$admin_user:$admin_pass" http://localhost:$port/3.1/system/versions
```
Sadly, the service takes longer than 10 seconds to start. Here's an excerpt (with debug logs enabled) in an amd64 VM:

^ in the example above, the webserver was started 19 seconds after the
master process was started.

It could just be a performance issue of the test-bed. Although I am
surprised to see that so far Debian is having better success with their
runs.

Since the "sleep 10" is a pretty arbitrary value, I suggest with bump it
up to 30 seconds and see if it helps.
