My understanding was that, after creating a new Electrum wallet (on Tails), Electrum would prompt me to write down the seed as one of the first steps. However, in my case, this was different...
That's if you select "
Standard Wallet->Create a new seed".
I did the following steps:
-> Create/Restore wallet -> default_wallet -> Import Bitcoin Address or Private Key (scanned the QR code of the paper
wallet with an USB cam) -> Wallet -> Private Keys -> Sweep -> scanned the QR code with an USB cam
It's a good thing that it didn't work since these steps would have sent the paper wallet's bitcoins to that same paper wallet.
Exposing the cold-storage private key on an online machine for nothing.
Now for the "
No inputs found" message, click the "
Info" button on the upper-right hand side of that 'Sweep private keys' window.
If unsure or the script type isn't indicated in your paper wallet, you may type your private key with three different script types.
For addresses that start with '1': you can skip "
p2pkh:" and just type the WIF private key for it to include P2PK UTXOs.
