daemon error: Exception in main! Failed to initialize p2p server

Question

following up with starting a recovered wallet:

I've recovered a deterministic wallet by entering the twenty five word seed and am not seeing any balance. From recollection, there's something about connecting to a node, if that's the correct terminology.

[wallet 42mEMY]: 
[wallet 42mEMY]: balance
Currently selected account: [0] Primary account
Tag: (No tag assigned)
Balance: 0.000000000000, unlocked balance: 0.000000000000
[wallet 42mEMY]: 
[wallet 42mEMY]: status
Refreshed 1/1, synced, daemon RPC v1.13, no SSL
[wallet 42mEMY]: 
[wallet 42mEMY]: refresh
Error: Daemon uses a different RPC major version (1) than the wallet (3): http://localhost:18081. Either update one of them, or use --allow-mismatched-daemon-version.
[wallet 42mEMY]: 

The daemon isn't connecting to the blockchain?

I also tried:

nicholas@mordor:~$ 
nicholas@mordor:~$ monerod --db-sync-mode safe:async:1000

I have a vague recollection of configuring the daemon but don't recall how that was accomplished.

This seems to work now:

However, it seems to be a large download.
