[Bug 1835738] Autopkgtest regression report (python3-stdlib-extensions/3.7.5-1~19.04)

[Ubuntu SRU Bot]

All autopkgtests for the newly accepted python3-stdlib-extensions (3.7.5-1~19.04) for disco have finished running.
The following regressions have been reported in tests triggered by the package:

thonny/3.1.1-1 (s390x)
python3.8/3.8.0~a3-2 (amd64, arm64, s390x, i386, armhf, ppc64el)
pandas/unknown (armhf)


Please visit the excuses page listed below and investigate the failures, proceeding afterwards as per the StableReleaseUpdates policy regarding autopkgtest regressions [1].

Bug description:
  Update Python interpreter to 3.6.9 and 3.7.5.  As done with earlier
  subminor upstream releases (LP: #1822993).

  SRU: update Python 3.7 to the 3.7.5 release, update Python 3.6 to the
  3.6.9 release.

  python3-stdlib-extensions also updates the modules to the 3.6.9
  release for Python 3.6.

  Acceptance Criteria: The package builds, and the test suite doesn't
  show regressions. The test suite passes in the autopkg tests. The new
  packages don't cause regressions in a test rebuild of the main
  component.

  TODO: update after test rebuild
  http://people.canonical.com/~doko/ftbfs-report/test-rebuild-20190404-cosmic.html
  http://people.canonical.com/~doko/ftbfs-report/test-rebuild-20190404-gcc8-cosmic.html

  The test rebuilds are finished, and don't show any regressions for the
  main component.

  Regression Potential: Python 3.7 isn't used by default, so we don't have many default users.
  Regression Potential: Python 3.6 could see some regressions, although we are trying to minimize the risk by doing the test rebuild.
