[Bug 2067361] [NEW] Programs using netrc with containing an entry without a password fail with an exception "malformed machine entry <> terminated by ''"

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Eero Aaltonen (ejn):

Some services use provide token authentication, where the users token is input as the "username" field, resulting in a netrc entry containing
```
machine SOME_ADDRESS
login SOME_TOKEN
```

but no password entry.

Trying to run some python based program, that uses netrc, such as
```
ansible-galaxy collection install SOME_PACKAGE
```

with this such a netrc file will fail with an exception
"malformed machine entry SOME_ADDRESS terminated by ''".

This is upstream bug https://bugs.python.org/issue34908 fixed in
python3.11.

[ Impact ]

 * Users are not able to run Python based programs using netrc
credentials, such as ansible.

[ Test Plan ]

 * Install ansible with `sudo apt install ansible`

 * Add an entry to ~/.netrc containing only the "machine" and "login"
tokens

 * observe failure when trying to run `ansible-galaxy collection install
community.crypto`

[ Where problems could occur ]

 * Some over specific test suite relying on current overly strict
parsing. However such a test suite would have to be fixed for python3.11
anyway.
