I’m having an issue when running cabal-build-all.sh:
Any idea what the issue is? I haven’t had luck resolving this yet.
Try running this -
$CNODE_HOME/scripts/cabal-build-all.sh -o
What operating system are u using?
my operating system is Ubuntu 20.04.2 LTS
running $CNODE_HOME/scripts/cabal-build-all.sh -o resulted in the same error
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.

. “${HOME}/.bashrc”
if you are using guild operator steps then follow this.

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. 
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.
