Update Cardano Node - 1.26.2 to 1.27.0 - For Non-CNTools or Coincashews users

Cardano Node 1.27.0 is out!

IMPORTANT: Take a Backup/Snapshot from your Nodes!!!

– Download new binaries –

cd $HOME/git
rm -rf cardano-node-old/
git clone https://github.com/input-output-hk/cardano-node.git cardano-node2
cd cardano-node2/

– Upgrade ghcup and cabal –

ghcup upgrade
ghcup install ghc 8.10.4
ghcup set ghc 8.10.4
ghc --version
ghcup install cabal
ghcup set cabal
cabal --version
cabal update

If your version is not on 8.10.4 run command:
ghcup set ghc 8.10.4

– Checkout new Branch 1.27.0 and Compile –

cd $HOME/git/cardano-node2
git fetch --all --recurse-submodules --tags
git checkout tags/1.27.0
cabal configure -O0 -w ghc-8.10.4
echo -e "package cardano-crypto-praos\n flags: -external-libsodium-vrf" > cabal.project.local
cabal build cardano-node cardano-cli

Note: Depending on your server performance, this process can take between 20-60+ minutes.

– Check if cardano-cli and cardano-node updated to 1.27.0 –

$(find $HOME/git/cardano-node2/dist-newstyle/build -type f -name "cardano-cli") version
$(find $HOME/git/cardano-node2/dist-newstyle/build -type f -name "cardano-node") version

This should print versions 1.27.0

– Stop old Cardano Node 1.26.2 and replace Binaries with the new Version –

sudo systemctl stop cardano-node

– Copy Binaries to bin folder –

sudo cp $(find $HOME/git/cardano-node2/dist-newstyle/build -type f -name "cardano-cli") /usr/local/bin/cardano-cli
sudo cp $(find $HOME/git/cardano-node2/dist-newstyle/build -type f -name "cardano-node") /usr/local/bin/cardano-node

– Verify Version –

cardano-node version
cardano-cli version

– If versions 1.27.0, you can start your node –

sudo systemctl start cardano-node

– Check your node progress –

journalctl --unit=cardano-node --follow 

– Clean up old directories –

cd $HOME/git
mv cardano-node/ cardano-node-old/
mv cardano-node2/ cardano-node/

Hope this helps!


Not sure what I may be doing wrong, but the “$HOME/git/cardano-node2/dist-newstyle/build” directory is empty, hence the verification commands to -check if cardano-cli and cardano-node updated to 1.27.0- part results in the following:
(** :~/git/cardano-node2$ $(find $HOME/git/cardano-node2/dist-newstyle/build -type f -name “cardano-cli”) version
version: command not found -**)

Any suggestions?

To add to my previous comment:
Upon running “cabal build cardano-node cardano-cli”
(which is the step prior to the verification mentioned in the previous comment)

The result is:
Failed to build basement-0.0.11.

*** UPDATE *** Found my answer. I was missing libnuma -dev. Once I installed ( apt-get install -y libnuma-dev ) The install progressed smoothly.

Glad you were able to find the solution - my sincerest apologies as I have been away from the forums.
