Cardano-node lock: openFd: permission denied

the real problem is that db folder has different owner, related topic:

Cardano-node: Missing protocolMagicId

yes - I dont know where this cardano user came from, but you can modify the ownership the folder by: sudo chown -R alberto:alberto /home/cardano/cnode WAIT! just realized then you are operating everything in home folder of cardano user… probably better to switch the user to cardano from alberto!
