Looking inside asyncssh/sk.py there is an attempt to catch ImportError on non-windows machines but an AttributeError happens instead. My unconfirmed guess is that this is due to recent changes in the fido2 package? I was able to get over this issue with this patch:

On Debian Sid the problem occurs since fido2 was updated from 2.0.0 to 2.2.0, I can confirm that the patch @cdleonard described works. Though I think it'd be preferable to not even attempt the import on non-Windows platforms.

[ronf]

Thanks for the report and the analysis. I'm able to reproduce this here after upgrading the fido2 package from 2.0.0 to 2.2.0. Since AsyncSSH doesn't directly reference HRESULT, though, I'm not sure I like the workaround of importing that. I'm leaning toward just catching either ImportError or AttributeError during the import of WindowsClient.

An alternative would be to surround this in a check of sys.platform for 'win32', but that would be a bit ugly as I'd have to repeat the setting of WindowsClient and sk_use_webauthn in both the "except" clause and in an "else" clause.

Here's what I'm testing:

diff --git a/asyncssh/sk.py b/asyncssh/sk.py

This catches the error in fido2 when importing it, in a generic way which doesn't need to know about what changed that triggered the error.

The above fix is now available as commit d2653a1 in the "develop" branch and will be included in the next release.

[airtower-luna]

The catch with that approach is that it might break again on another change to what's the first exception that occurs when you try to import fido2.client.windows on a non-Windows platform. I guess except Exception would be an option, but that could hypothetically hide some other error that actually should be fixed. 😅

Maybe something like this could work?

WindowsClient = None # type: ignore
sk_use_webauthn = False
if hasattr(ctypes, 'windll'):
    try: # pragma: no cover
        import fido2.client.windows
        sk_use_webauthn = fido2.client.windows.WindowsClient.is_available() and \
                          not ctypes.windll.shell32.IsUserAnAdmin()
        WindowsClient = fido2.client.windows.WindowsClient
    except ImportError:
        pass

Not sure if that's the best way to test "are we on Windows", but it was already there, and I'm sure you get the general idea. 🙂

[ronf]

You're right that not importing WindowsClient on a non-Windows system would be more future-proof. This was what I was referring to when I mentioned testing for sys.platform. However, it may not solve the problem if the issue is due to incompatible changes in fido2 on Windows itself, which I've run into in the past when upgrading to new fido2 versions.

There's actually already a precedent for testing for AttributeError in fido2 in sk.py in cases like this. It does this when importing the main set of fido2 modules. As fido2 has cycled through its various versions, I've seen various exceptions raised when the version of fido2 on the system doesn't align with what a given AsyncSSH version supports. So, even with the sys.platform check, the list of exceptions to look for might need to be adjusted over time to prevent other sources of breakage on Windows.
