Public bug reported:
Removing a lot of the output since Launchpad is not going to format it
properly anyway:
$ glance-manage -h
...
argparse.ArgumentError: argument command: conflicting subparser: db_version
This happens because the argparse module became stricter in Python3.11 and
prevents us from adding the same subparser twice:
$ cat parser.py
import argparse
parser = argparse.ArgumentParser()
subparsers = parser.add_subparsers(title='Commands')
subparsers.add_parser('foo')
subparsers.add_parser('foo')
subparsers.add_parser('bar')
parser.parse_args()
$ python3.10 parser.py
$ python3.11 parser.py
Traceback (most recent call last):
File "/tmp/parser.py", line 6, in <module>
subparsers.add_parser('foo')
File "/usr/lib/python3.11/argparse.py", line 1197, in add_parser
raise ArgumentError(self, _('conflicting subparser: %s') % name)
argparse.ArgumentError: argument {foo}: conflicting subparser: foo
