According to debian/README.source (which was written when Ubuntu 22.04
was current), our policy is:
> If it's straightforward to avoid a newer dependency without too much
> extra code, we can consider extending [the supported host system] to:
>
> - previous Debian stable
> - previous Ubuntu LTS
>
> As of mid 2023, this means Debian 11, Ubuntu 20.04 and Python 3.8.
Now that Ubuntu 24.04 is current, I'd like to officially increase the
recommended host system to Debian 12 or Ubuntu 24.04, and increase the
minimum to Debian 11 or Ubuntu 22.04. That would mean we can rely on
Python 3.9:
- replace List[Set[str]] with list[set[str]], etc.
- dict1 | dict2
- str.removeprefix, str.removesuffix
- pathlib.Path.readlink
- stderr is line-buffered
Please check whether any Ubuntu infrastructure is relying on being able
to run a current version of autopkgtest on a 20.04 host system.
We could also consider changing the policy from "previous Debian stable"
to "previous Debian stable, if still supported outside LTS", which
would mean we can drop Debian 11 support now that it has moved to LTS,
and rely on Debian 12 or Ubuntu 22.04, with Python 3.10:
- replace Union[str,bytes] with str | bytes
- multiple context managers can be in parentheses
- structural pattern matching
Note that this is about the supported host OS version (host for VMs,
containers, etc.). For the the testbed (the system under test, inside VMs,
containers, etc.) we continue to allow very old versions, although this
is "at risk" until/unless someone from Debian (E)LTS or Ubuntu ESM can
fix #1078445.
