Dear maintainer(s),



The following removed libraries were found in this package:

Python 3.13 removes a large amount of so called 'dead battery' libraries from the standard library. As such, code that imports these libraries will no longer work in Python 3.13, which is the targeted version for Trixie. cgi: third_party/depot_tools/external_bin/gsutil/gsutil_4.68/gsutil/gslib/vendored/boto/boto/ecs/item.py:24 cgi: third_party/depot_tools/external_bin/gsutil/gsutil_4.68/gsutil/gslib/vendored/oauth2client/oauth2client/contrib/appengine.py:20 cgi: third_party/depot_tools/external_bin/gsutil/gsutil_4.68/gsutil/third_party/apitools/apitools/base/protorpclite/test_util.py:29 telnetlib: third_party/depot_tools/external_bin/gsutil/gsutil_4.68/gsutil/gslib/vendored/boto/tests/integration/ec2/test_connection.py:30 imghdr: third_party/webdriver/pylib/test/selenium/webdriver/common/takes_screenshots_tests.py:19 imghdr: third_party/webdriver/pylib/test/selenium/webdriver/firefox/ff_takes_full_page_screenshots_tests.py:19

FYI, I don't believe our chromium build actually _uses_ any of these scripts. I'll obviously fix anything that breaks once the deprecated modules are removed in python 3.13, but as they're mostly depot_tools (use for upstream development) and unit tests (which we don't run), I'm not too concerned.
