Some of you have recently encountered the following warnings:

![](/assets/blog/new-gpg-keys/warnings.png)

The reported error is due to the GPG keys used to sign the ParrotOS repositories being expired or invalid. Specifically, the message `EXPKEYSIG 823BF07CEB5C469B` indicates that the GPG key with the specified ID has expired (where EXP stands for "expired").

When using an apt based system (like ParrotOS/Debian) to download or update packages, the system verifies the integrity and authenticity of the repository files using digital signatures provided by the GPG keys.

### What is GPG?

GPG, or GNU Privacy Guard, is a free software for encrypting and signing data and communications. It's an implementation of the OpenPGP standard as defined by [RFC9580](https://datatracker.ietf.org/doc/html/rfc9580), which is how it is used in a variety of secure applications.

This is actually one of the mechanisms we use to ensure the secure installation of packages without external interference. Each package is signed with our GPG key.

## So, how can I solve this problem?

If `apt` notifies you that your GPG key has expired, here is the solution to get things back on track. Download and install the latest version of **parrot-archive-keyring** from [our repository](https://deb.parrot.sh/parrot/pool/main/p/parrot-archive-keyring/parrot-archive-keyring_2024.12_all.deb):

[https://deb.parrot.sh/parrot/pool/main/p/parrot-archive-keyring/parrot-archive-keyring_2024.12_all.deb](https://deb.parrot.sh/parrot/pool/main/p/parrot-archive-keyring/parrot-archive-keyring_2024.12_all.deb)

Once installed, the new key with **ID 7A8286AF0E81EE4A** will replace the expired key **ID 823BF07CEB5C469B**. To ensure everything is correct, the SHA256 hash of the downloaded *.deb* file should be:

```
$ sha256sum ./parrot-archive-keyring_2024.12_all.deb
$ 188c74cf726fad499ec416dc6b7dcd9718800aa7178290c10ef7040aea9b5272
```
