all autopkg tests triggered by python3.9 pass, all autopkg tests
triggered by python3-stdlib-extensions pass. except for
1 test failed:
test_ttk_textonly
this test is already ignored for python3.9, and also will be ignored
with the pending update of 3.8 to 3.8.10, tracked in LP: #1928057.
Suggesting to ignore that one here, the Tcl/Tk bindings are not much in
use, and checked that idle continues to work with the update.
** Tags removed: verification-needed verification-needed-focal verification-needed-groovy verification-needed-hirsute
** Tags added: verification-done verification-done-focal verification-done-groovy verification-done-hirsute
** Description changed:
- Backport python 3.8.6 and 3.9.0 to focal.
+ Backport python 3.9.5 to groovy and focal.
Regression potential: ...
Validation: Test results show no regressions, and the archive test
rebuild doesn't show any regressions.
Acceptance criteria:
- - 21.04: 3.9 is the default version. check test suite and autopkg test results
- - 20.04 LTS and 20.10: not used in the archive, just check test suite
+ - 21.04: 3.9 is the default version. check test suite and autopkg test results
