So I tried the multisig guide over there ---> to try and setup electrum 2.0.whatever on tails. I followed the guide and the server settings but it still kept giving me leaky data errors. Now I can't load that wallet at all and I'm using electrum 1.9.8 on a different tails usb. (I couldn't seem to figure out how to get rid of the 2.0 and downgrade back to the 1.9.8)
So if someone could do a little walkthrough with a better wallet that is more tails compatible, I'd be highly appreciative. I really want to get in on some of TheGrandWizard'sLair's multisig action.
Once you've upgraded your wallet there's no going back. Although I don't see a reason to, if you absolutely need to get back to 1.9 you'll need to create a new wallet and transfer your coins there.
As for your question, I wrote a plugin for electrum that makes multisig easy on blackbank. There are also other ways using external websites , and you can find a guide for that on deepdotweb. With the default electrum multisig you won't be able to do it.
