GPG sign and verify deb packages
Signing data with a GPG key allows the recipient of the data to check whether any modifications have occurred after the data was signed.
Since release 1.22.0, each Debian package file (.deb file) has been signed with a GPG key, and the signature is included in the archive.
The Public Key has been uploaded to https://keys.openpgp.org/search?q=EA267657A608300C296B8F8AD52C9665A4077678
To verify the signature:
# Download and import the Public Key
curl https://keys.openpgp.org/vks/v1/by-fingerprint/EA267657A608300C296B8F8AD52C9665A4077678 | gpg --import
# Download the driver package
wget https://github.com/intel/linux-npu-driver/releases/download/v1.22.0/linux-npu-driver-v1.22.0.20250813-16938856004-ubuntu2404.tar.gz
tar -xf linux-npu-driver-v1.22.0.20250813-16938856004-ubuntu2404.tar.gz
