Fixes:
- Unpin all package versions installed on the Attacker during the provisioning step.
Note: While we generally aim to pin OS and package versions in SOCBED for better reproducibility, we dismiss this practice for packages on the Attacker since Kali is a rolling release distribution and removes older packages from their default repo after a while, leading to failing SOCBED builds. If reproducibility is of higher importance to you than being able to access up-to-date Kali packages, you might replace its default repo with a point release repo (see https://old.kali.org/).
