Getting a "your password no longer matches your keyring" error when I try to access my VPN on Kali Linux

I had to reset my root password and now I'm having this issue when I try to access my VPN on Kali Linux:

Your password no longer matches your keyring.

Does anyone have any idea how to solve this?

All the solutions I can find are for Ubuntu and don't seem to to work for Kali.

I had the same problem before finding this thread, here. I think, or better said, I'm sure that removing ~/.gnome2/keyrings/login.keyring will work on older versions. I have recently upgraded to kali 2020.1 and this is what worked for me. You can remove the login.keyring file altogether. If you consider you may need it, just make a backup:

cd ~/.local/share/keyrings/
cp login.keyring login.keyring.backup

Check it with ls I had both files, login.keyring and login.keyring.backup, along some other. I have removed without remorse the login.keyring one.

rm  -f ~/.local/share/keyrings/login.keyring

After checking with ls you'll see that it was removed. I did that operation which triggered the annoying popup, and this time the popup didn't show up. Good luck!

Remove the ~/.gnome2/keyrings/login.keyring file. After that, you should be prompted to set a new password. Make sure it matches the one used for logging in.
