As I was getting to know how to use this i wanted to test it against just few users (knowing which are good and which wrong) and few passwords (with one right).
Discovering users work fine, but I always get "no password discovered" even though I know there is one correct pair.
After adding -debug, and get an error:

I am running it on clean, freshly installed deb10, with locally hosted krb5-kdc. Kerbrute was installed via pip3.
Got any idea what can be the problem and how to solve it?
I'm unable to run kerbrute, neither with python3 or python3.9, i got:

Also installing through pip i get same error :-(
Hi,
i have installed Kerbrute on Kali Linux, but the version is old and thus does not work correctly, is the repository outdated?
