I was using Electrum 3.4...i presume, latest on a Mac...sent Bitcoin to an older version and it says it went through but i cannot open Electrum anymore on my Debian system.

I have the txn file generated by Electrum

Advice?

Did you save the 12 word seed phrase somewhere? You need either the wallet file, or the seed phrase. Without it, you can't recover Bitcoins.

As long as you have your seed (12 words) you are safe, just Loycev said.

Just download a new software in electrum.org
And recover your wallet using the seed you have.

i have the seed...but the transaction completed...Eletrum turned off their servers during the transaction.

"Known issues
Electrum is outdated and cannot connect to servers

Electrum in Tails cannot connect anymore to Electrum servers.

The version of Electrum in Tails is vulnerable to a phishing attack that tricks people in updating to a malicious version of Electrum which is not distributed from the official Electrum website.

You are safe unless you try to do the malicious update manually.

To prevent this phishing attack, all trustworthy Electrum servers now prevent older versions from connecting to them.

Unfortunately, newer versions of Electrum are not available in Debian and cannot be integrated easily in Tails. Given the lack of maintenance of Electrum in Debian, we are still assessing what is best to do in Tails.

Until then, your wallet is not lost and you can restore it from its seed using an up-to-date version of Electrum outside of Tails."

if the transaction completed...how do i get back what was deemed a successful transaction?

Assuming this is correct, your funds are safe. Just keep the seed!

If you don't want to use anything other than Tails, waiting for a newer version seems to be the easiest right now. You can of course export your private keys and switch to a different wallet, but I don't recommend doing that if you're not absolutely sure what you're doing.

Install the latest version of Electrum (https://electrum.org/#home) from the official website (and nowhere else!), import your seed, and your funds should show up again.

i will try to manually install in on tails...im not well versed in python...but i have no choice!

trying to post a screenshot...JIC...

I think it would be fine if you install it manually why not upgrading the old electrum wallet?

Anyway, I think you need a guide for this and I found a guide from Google that you can follow check this Upgrading electrum on tails to 3.3.4 (https://blog.thestever.net/2019/02/26/upgrading-electrum-on-tails-to-3-3-4/)

Just make sure the source comes from https://electrum.org/#download

Your Electrum version was outdated.
This error is the combination of the developers and the legitimate servers' efforts to "tell" users with vulnerable versions of Electrum to update to the latest version.
And just recently, they are using DOS attack to old Electrum versions.

• Electrum clients older than 3.3 can no longer connect to public electrum servers (https://bitcointalk.org/index.php?topic=5120865.0)
• we have started to use the same vulnerability, and to direct them to electrum.org (https://bitcointalk.org/index.php?topic=5109152.msg49711414#msg49711414)
