http? really?
Anyway, those last lines are useless, this is the relevant part:

I included the warning as it is present numerous times in the build log,
but it's the second that causes a/the build failure.
While I'm at it, let's also quote another warning:
```

```
Interestingly enough, in the upstream repo there is this issue:
https://github.com/pocoproject/poco/issues/4695
"Build error with GCC-15 (class Poco::PriorityDelegate<TObj, void,
true>’ has no member named ‘_pTarget’)"
but that error is NOT present in the build log. I guess it fails before
it got to that?
There seems to be several issues with the build environment:
```
dpkg-deb: warning: root directory /build/reproducible-path/resolver-FT9kbW/sbuild-build-depends-main-dummy has unusual owner or group 104:110
dpkg-deb: hint: you might need to pass --root-owner-group, see <https://wiki.debian.org/Teams/Dpkg/RootlessBuilds> for further details
dpkg-deb: warning: ignoring 1 warning about the control file(s)
...
dpkg-source: warning: cannot verify inline signature for ./poco_1.13.0-6.dsc: unsupported subcommand
```
("..." denote several omitted lines)
