It's an armory wallet backup. Who does it belong to?

Like HCP said this is all nonsense.

Fact is in previous Electrum versions 2fa wallets had 24 or 25 word seeds. But now it's just 12 words.

In previous versions half the 24 word seed was viewable via the wallet menu > seed after the wallet had been created. So you could view 12 of the words there but they were useless and misleading because they wouldn't restore your wallet. You needed all the seed words i.e. 24 or 25. Maybe this is the source of the jackg's confusion.

In newer versions of electrum the 12 seed words are only shown during the wallet creation process. You can't see them later so you better write them down during the wallet creation process.

Electrum strives to maintain backward compatibility so all types of 2fa wallets can be restored from seed in Electrum.

Bring the addresses tab into view via the view menu. Then switch to that tab, ctrl+f to search for the address in question, right click on it and choose the option to view the private key.

1. Switch to a different server: https://bitcoinelectrum.com/how-to-switch-to-a-different-electrum-server/
2. Yes. Also it'll show blank if you haven't done any transactions with the wallet.
3. You should write down the seed words (wallet > seed) and also create a soft copy backup of the wallet file via file menu > save copy. If you don't save either of those two things then your coins will be lost in the event of a hard drive problem.

the wallet type is mentioned in the electrum window title. tell us what it says there for the wallet with the bitcoins in it.

if they haven't sent the bitcoins then it's there fault not electrum's. contact them.

another option is to extend your seed with custom words. you keep those in your head while the seed gets put down on paper. if you forget the custom words then you'll lose your bitcoin so it's risky. it's like a password for the seed.

once the coins are swept to a new address it won't matter if the paper wallet priv keys have been exposed.

you have it absolutely correct.  you don't need to store anything else.

if you don't mind exposing your paper wallet private keys then just sweeping into a watch only wallet on the online computer will do the job. considering that the paper wallet will be emptied when you sweep it there is minimal risk IMO.

Do you have a copy of those imported private keys somewhere? Search for it.

Other than that it's the same thing we advise all people with lost passwords:

1. Open a text file and start typing in whatever you remember about the password. Maybe you used the same password everywhere? Write down whatever ideas you have about it.

2. Try the gurnec script linked above or use the services of walletrecoveryservices.com . If you choose to go with the latter then share that text file with Dave so he has an idea what passwords you might have used. Otherwise it's a stab in the dark for him.

That's all there is to it.

Electrum's native seeds are not BIP39. The reasoning behind this is given in this post on the bitcoin development mailing list:

https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2016-August/013061.html

So you can only restore an electrum wallet in electrum. You can restore a mycelium wallet in electrum as Potato Chips said above. You just have to click on options and check bip39 when you get to the seed entry screen during the wallet creation process.

sorry for your loss. in future don't drink and bitcoin!

It will generate new addresses which is why a private key backup is a very dangerous thing to rely on. Your coins will eventually be moved to the new addresses by Electrum and you will be SOL. You should backup only the 12 word seed mnemonic.

There is nothing you can do because your wallet contains multisig addresses and there is more than one private key behind each of them. Your wallet file only contains one of those private keys for each address. So there is no way to recover your funds with just one private key. You need the seed or the 2fa code.

Sorry for your loss.

You can restore from seed via file menu > new/restore. Enter a file name for the new wallet file and follow on-screen instructions for the rest.

Edit: Please create your own thread.

sudo -H pip2 install /path/to/tarball

i think you figured this out already but the problem appears to be network related. you should download the tarball manually using a browser and then run pip2 on it

Yes that's interesting. It shows a blue dot when you use a proxy

python-setuptools is sometimes required in debian and derived distros so that's why I mentioned it.
