Thank you for sharing this!
Iāve hit this snag, not sure what is the problem, any ideas?

Resolving dependenciesā¦
@Viggy you are a hero. This resolves a hand full of issues that have been causing me much pain the past few weeks. Thank you immensely for your contributions.
Thank you! So helpful! Just wondering if you guys can help a newbie out, where do I find the version I need to be running? Is there a webpage somewhere that shows what version is running on mainnet and testnet?
I was banging my head against the wall trying to figure out why my node would not connect and the error output isnāt very helpfulā¦
Here you can always see the current status of the network:
The first āVersionā info block chows that at the moment 97% of all pools are running on v1.25.1. Pools below that version are still there but their owners probably forgot they have a pool.
Edit, topology wasnāt updating. Had to change this line blockNo=(/usr/local/bin/cardano-cli query tip {NETWORK_IDENTIFIER} | jq -r .block )
the block on the end used to be blockNo.
I used this to go from 1.25.1 to 1.26.1 as well and it seemed to work just fine. I am still on cabal 3.2.0.0 and ghc 8.10.2 though. Didnāt realize there was new versions out. Is that a problem? Should I update them now that Iām already on 1.26.1?
I updated all my relays and a node from 1.25.1 to 1.26.1 with the following commands. I recommend you running those step by step. Do not just copy the whole text and paste it. It may ask for a password at sudo commands again after a long build process.

# START THE NODE
# !!! IMPORTANT, VERSION 1.26.1 REQUIRES DB MIGRATION
# IT MAY TAKE 30min OR MORE DEPENDING ON YOUR CPU
# MIGRATION PROCESS WILL START AUTOMATICALLY AFTER YOU START THE NODE
# YOU CAN CHECK MIGRATION STATUS BY RUNNING: journalctl -u cardano-node.service -f
# READ BELOW IF YOU ALREADY HAVE ONE NODE UPDATED AND MIGRATED
sudo systemctl start cardano-node
Once you have at least one node updated and migrated, you can save time with migration by copying migrated DB before running the last command (starting the node). To do that run: rsync -arzv --delete --delete-during username@YourMigratedNodeIP:/home/cardano/cardano-my-node/db/* $NODE_HOME/db/
You need to run this command on a non-migrated node to copy files from external YourMigratedNodeIP, Make sure you change the username, IP and paths correctly.
