# IC-OS Verification

To build and verify the IC-OS disk image, run:

```
# From https://github.com/dfinity/ic#building-the-code
# This process requires Mac/Linux/WSL2, Git and Podman on your machine.
git clone https://github.com/dfinity/ic
cd ic
git fetch origin
git checkout 5058a1326d45303de376cd1a1dc5303fa27cdb07
if ./gitlab-ci/container/build-ic.sh -i ; then
    curl -LO https://download.dfinity.systems/ic/5058a1326d45303de376cd1a1dc5303fa27cdb07/guest-os/update-img/update-img.tar.gz
    shasum -a 256 artifacts/icos/update-img.tar.gz update-img.tar.gz
else
    echo "IC-OS build failed. Verification unsuccessful." >&2
fi
```

The two SHA256 sums printed above from a) the downloaded CDN image and b) the locally built image,
must be identical, and must match the SHA256 from the payload of the NNS proposal.
