It appears 1.28 has been released at Releases · input-output-hk/cardano-node · GitHub

Are we supposed to have already updated servers? The instructions below are still stating 1.27:

Not official released yet

I accidentally upgraded to 1.28.0 and my node is not working anymore.

Any help on how can I roll it back to 1.27.0 I’m using cntools

What do u see?

journalctl -e -f -u cardano-node

U are using cntools

journalctl -e -f -u cnode

Also do u want to use 1.28.0 or 1.27.0?

Yes I installed 1.28.0. And stopped working. I wan’t to roll back to 1.27.0. This is what it shows. thank you

Yeah, u don’t have the files for alonzo

If u will want to downgrade then

Stop the node

cd ~/git
cd cardano-node

git fetch --tags --all
git checkout 1.27.0

echo -e "package cardano-crypto-praos\n  flags: -external-libsodium-vrf" > cabal.project.local

Start the node


Did you have a backup feature installed that you can use to roll back? If you don’t, I highly recommend that you implement one. It can be very useful in such situations.


Thanks worked perfectly!

Found this issue now. Although it is working now the node status never changed from “starting”image

also see below

Try to run again
cd ~/tmp
./prereqs.sh -f and restart the node

Yeap. That was it. I had forgotten to change back the port in the env file after reinstalling. Now it’s syncing all good, let me know If I can buy you a beer man. Thanks!!
