Incorrect padding error

Hi, it the past it worked well. But now I have problem with using openconnect-sso. I get this error:

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

    msg, retval = e.args
ValueError: not enough values to unpack (expected 2, got 1)

Do you have any idea why and how can I fix it?

Thank you for your help.

I have the same problem on Fedora 39 with python3.12.3.

Deleting the keyring entry fixed it for me

Deleting the keyring entry fixed it for me

Can you please describe it more? I don't have keyring entry in my config file and I don't know where it is located.

[shell-raiser]

The creds are stored in the login keyring when you use --user user@domain.com like this.

You can use a GUI application like seahorse to manually delete associated password/creds

[andrashor]

I confirm that it worked after I deleted the creds stored in keyring. Thanks for the help. (I used seahorse in Fedora linux)

[marosrojis]

Me too, thank you.
