⚠️ Notice: Signing Key Rotation Required

Due to a key signing expiry, existing installations of the Tenstorrent repositories may fail to update their package listings. For example, you might see the following error when running sudo apt update:

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://ppa.tenstorrent.com/ubuntu noble InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 3A44817BAF0FE074 

W: Failed to fetch https://ppa.tenstorrent.com/ubuntu/dists/noble/InRelease  The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 3A44817BAF0FE074 

W: Some index files failed to download. They have been ignored, or old ones used instead.

To resolve this error, please rotate the key. On Ubuntu, run this command:

sudo wget -O /etc/apt/keyrings/tt-pkg-key.asc https://ppa.tenstorrent.com/tt-pkg-key.asc

On Fedora/RHEL systems, follow the "Add the repository configuration" step from the instructions below. The error should be resolved. We apologize for any inconvenience; please contact us on Discord or open a support ticket if you have questions.
