I’m one day away from my KES expiration date and have used the CoinCashew guide to generate new kes.vkey and kes.skey. My new KES period is 258.
I copied the kes keys to my air-gapped machine and ran the cardano-cli node issue-op-cert command but first was receiving errors. That my kes.vkey was invalid. I regenerated new keys and tried again, but now it says
command failed: node issue-op-cert Error:/home/airgap/cold-keys/node.counter: openBinaryFile:permission denied.
I have unlocked the cold-keys folder with
chmod u+rwx $HOME/cold-keys but to no avail.
Do you know the best way forward? Thanks!
