Kali Linux’s maintainer, OffSec, has lost the repository signing key. This means updates will fail until you manually install the new key.
Offensive Security, the company that maintains Kali Linux, has some bad news for users. If you use Kali Linux, you might soon find that your system is unable to update its software.
The reason is that Offensive Security lost access to the signing key used for the Kali software repository. Linux systems rely on these cryptographic keys to verify the authenticity and integrity of packages before installing them. When the expected key is missing or incorrect, the package manager, apt, throws an error and refuses to proceed with updates.
The Kali team stated that the repository was frozen for a few days, but it is now being unfrozen, and updates are signed with a new key.
