build succeeded, 10 warnings.

The HTML pages are in ../../debian/python-sqlalchemy-doc/usr/share/doc/python-sqlalchemy-doc/html.

Debian's 1.3.22-ds1-1 build sees none of these error messages:
https://buildd.debian.org/status/fetch.php?pkg=sqlalchemy&arch=amd64&ver=1.3.22%2Bds1-1&stamp=1609355330&raw=0

The version carried in impish was sync'd in Dec 30th, 2020, so hasn't received a rebuild in a while:
https://launchpad.net/ubuntu/+source/sqlalchemy/1.3.22+ds1-1

It sounds like the warning for the Libre+Franklin import is ignored by the testsuite, however I wonder if this results in either dummy data or an error html page to be used in place, and that this triggers the secondary error (below).
It is mentioned at https://github.com/sqlalchemy/sqlalchemy/issues/5727, and sounds like the issue is that an external resource is attempting to be read but blocked by the proxy; a few workarounds are suggested there.

The secondary error occurs in python, and is what autopkgtest actually faults on:

Traceback:
  File "/usr/lib/python3/dist-packages/scss/compiler.py", line 349, in manage_children
    self._manage_children_impl(rule, scope)
  File "/usr/lib/python3/dist-packages/scss/compiler.py", line 359, in _manage_children_impl
    for c_lineno, c_property, c_codestr in locate_blocks(rule.unparsed_contents):
DeprecationWarning: PY_SSIZE_T_CLEAN will be required for '#' formats

python3-pyscss provides scss/compiler.py:

    # @print_timing(4)
    def manage_children(self, rule, scope):
        try:
            self._manage_children_impl(rule, scope) # line 349
        except SassBaseError as e:
            e.add_rule(rule)
            raise
        except Exception as e:
            raise SassError(e, rule=rule)

    def _manage_children_impl(self, rule, scope):
        calculator = self._make_calculator(rule.namespace)

        for c_lineno, c_property, c_codestr in locate_blocks(rule.unparsed_contents):
            block = UnparsedBlock(rule, c_lineno, c_property, c_codestr) # line 359
            ...

The error mentions a '#' format, but I'm not sure what data this UnparsedBlock() call is erroring on exactly. However, this DeprecationWarning on PY_SSIZE_T_CLEAN was introduced in Python 3.8 (c.f. https://bugs.python.org/issue36381) and has been dealt with by various other projects (e.g. LP: #1853809, https://github.com/zopefoundation/persistent/issues/108, https://stackoverflow.com/questions/66254152/suppress-deprecation-in-python, https://github.com/python-pillow/Pillow/pull/3749)

The current sqlalchemy package was built with python3-all-dev (>= 3.1.2-8~), which precedes when this deprecation was introduced.
