Upgraded cold storage wallet, cannot sign transaction

[rustbucket]

Hey there,

I am in the process of upgrading my wallet from 1.9.8 to 2.6.4. I use an offline wallet running Lubuntu 16.04 for cold storage and have a watching wallet on a Windows PC. I thought i'd take it step-by-step and first upgrade the cold storage wallet only before upgrading my watching wallet, perform a small BTC transaction to ensure everything is ok and then upgrade the watching wallet to 2.6.4.

I installed 2.6.4 on the cold storage laptop and using my seed I restored my previous wallet. I then made a small unsigned transaction with my watching wallet. However, when I load this unsigned transaction into my 2.6.4 cold storage wallet in order to sign it, it won't appear. That is to say, when I try to open the unsigned transaction using the 'Load Transaction' command - nothing happens.

The not-panicky part of my brain tells me that this is most likely because the cold storage wallet has generated a new series of addresses that no longer tally with those from my 1.9.8 wallet, but as i'm anything but confident in matters crypto i'm not sure. What might the problem be?

I'd appreciate some help on this! Thanks a million in advance,

Adrian

First of all you shouldn't have had to restore from seed when upgrading electrum on the cold storage machine. Electrum would have found your wallet and upgraded it automatically.

Second you didn't upgrade your watch only wallet? You should upgrade that and then create a new transaction to sign with the cold storage wallet.

Edit: I see from the other thread that you've made a right royal mess of things. Sorry but you shouldn't be using linux and doing offline/cold wallets unless you really know what you are doing. I suggest upgrading electrum on your watch only system, creating a new wallet*, select restore and enter your seed. This will bring your wallet online. Then you can use it as a regular online wallet and forget about complicated cold storage.

* to create a new wallet select file menu > new/restore, choose to restore a standard wallet. to open this wallet in future use file > open.

Well, anyway, thanks for your willingness to help.

You can listen to Abdusammad without a problem, I am using Electrum 2.5.4 since it first came out and keeping it online, not in offline storage, I use Linux and since I see you also use Linux, just make sure to safe guard your SEED in some other places (External HDD or USB-S at least 3 of them so you are sure not to miss it) never put these USB-s in any other computers except your Linux machine. Add a very strong password, I use a 13 characters one with capital letters, and special characters and Electrum rates it very strong. You should be good to go. If you use this pc only for bitcoin activities like sending and receiving only and not open suspicious links (linux is strong but vulnerable too) you can forget about complicated cold storage and do normal use of Electrum on your Linux machine.

Its been a long time I am doing this and have more than 1 Bitcoin stored on it , not a single problem so far, it should be the same for you I think.
