# 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# This process requires an x86-64 based machine, Ubuntu 20.04 or a newer version of the OS, Git, and Podman.
git clone https://github.com/dfinity/ic
cd ic
git fetch origin
git checkout 7742d96ddd30aa6b607c9d2d4093a7b714f5b25b
if ./gitlab-ci/container/build-ic.sh -i ; then
    curl -LO https://download.dfinity.systems/ic/7742d96ddd30aa6b607c9d2d4093a7b714f5b25b/guest-os/update-img/update-img.tar.gz
    shasum -a 256 artifacts/icos/guestos/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.
