IC-OS Verification

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

# From
# This process requires an x86-64 based machine, Ubuntu 20.04 or a newer version of the OS, Git, and Podman.
git clone
cd ic
git fetch origin
git checkout 0062aec2efc16d6e4cadb2cd1052aaabbc9f6e48
if ./gitlab-ci/container/ -i ; then
    curl -LO
    shasum -a 256 artifacts/icos/guestos/update-img.tar.gz update-img.tar.gz
    echo "IC-OS build failed. Verification unsuccessful." >&2

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.

Reviewers for the CodeGov project have completed our review of this replica update and our findings from the reviews can be viewed in this post for proposal 123711 in the CodeGov portal on DSCVR. The CodeGov neuron 2649066124191664356 has voted to ADOPT proposal 123711.

At the time of this comment on the forum, there are still 2 days left in the voting period. We encourage NNS voters to review the replica update proposal and vote manually. Of course, you always have the choice to follow another person or another organization who is voting independently. At this time, I am aware of (neuron ID 2649066124191664356) and Taggr Network (neuron ID 16737374299031693047) who are performing this work, both of which are registered known neurons. You can learn more about the CodeGov project at and you can learn more about Taggr Network in the NNS-GOV realm on

NOTE: The CodeGov project would like to find additional reviewers to help with this work. Since there is a 0.5 - 2 hour time commitment on the weekend for each proposal and our reviews require technical skills, we offer a bounty for every review that you perform that is competitive with typical developer contract work. You are not required to review every proposal, but we encourage as much participation as your time allows. Anyone who has the technical skill to perform the IC-OS verification and who is willing to perform a sanity check on the Release Notes is welcome to be a reviewer. If you are interested, then please Apply at The current bounty for this work can always be found in this post in the CodeGov portal.

Also, let me offer a special welcome to @ZackDS to the CodeGov project as a new reviewer. He started with an excellent review this week. Thank you for your help!
