UPDATE CARDANO NODE to 1.26.1 - FOR CNTOOLS users

did u ran the prereqs before?

Yes, I’m on GHC v8.6.5 if that makes any difference.

ghc - -version

I think u need 8.10.2

It’s telling me that 8.6.5 is the newest version when I try to run sudo apt-get install --only-upgrade ghc

Did u tried to update the server?

sudo apt-get update
sudo apt-get upgrade

sudo reboot

I found the fix:

One of the first steps has you install or update ghcup.

Running the 2 lines below worked for me:
curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh
source ~/.bashrc

My node is currently building.

Yep, I remembered to reload it.

I’m using CNTools setup

Regarding the db snapshot I just verified on my relay that there is no need to copy the immutable folder to shorten the re-syncing. Only the ledger and volatile folders need to be copied to other nodes.

hello Alex:
I upgraded my BP but in the gliveview headre it says relay - mainnet instead of core - mainnet
any ideas?
Do I need to run deploy-as-systemd.sh on the BP?

ghcup wasn’t required for 1.25.1 so that might be a comment that could be included in the update guide

It is synced? if not u will see relay

Hi Alex,
4 nodes successfully updated with your tuto. :innocent:
Syncing delay : relays : 1h40m, BP : 2h45m, with sometimes this red message “connection to the node lost”. But visibly no effect on syncing…
Cheers

I reboot my test relay server and don’t see any issues. All services are up and running.

Hello Alex:
After upgrading to 1.26 the tip (diff) is mostly yellow, is it normal? do you think I need memory or CPU I got 8RAM 4Vcpus.
Thanks

Yes, it is normal… As long u are not out of sync it is ok

for me all relays and producer took around 45minutes to complete the sync

How do I check for sync?cncli.sh sync?
