Astroquery: Login not possible when keyring cannot find a valid storage

[saimn]

When login on a server, I get this exception:

In [1]: from astroquery.eso import Eso
eso

I don't know why exactly (no dbus, gnome-keyring or whatever) but this should not prevent to login without storing the password. I can workaround this by using reenter_password=False but this is not obvious (login parameters are not documented).
So I guess the simple solution would be to try/except the keyring.get_password call :

        # Get password from keyring or prompt
        if reenter_password is False:
            password_from_keyring = keyring.get_password(
                "astroquery:www.eso.org", username)
        else:
            password_from_keyring = None

@saimn - What is your keyring version? We had issues with v12.0+ on CI, so if you have one of those, could you please try it with an older one, too?

[saimn]

@bsipocz - I have 12.2.1, let's try with another one.

[saimn]

I get the same error with 11.1.0 and 13.2.1.

It's unfortunate that keyring is causing us problems, but I agree with the solution of trying to get the password and giving up if there's a keyring-related failure
