Stuck transaction and old software

[SierraB]

I'm having nearly the same problem as the OP had:

 Tried to send  BTC to coinbase at the beginning of April from my old Bitcoin-qt wallet (0.8.6) but the transaction does not  even appear on the block chain. Interestingly, I was successful in sending coins from this wallet to the same address in March and February, although the wallet incorrectly says those transactions have zero confirmations.

I just wanted to check that the solution the OP was to try: install latest Bitcoin Core (now 0.14.1) and then run the "abandon transaction" command to get rid of the phantom transaction and restore the BTC that did not get sent - worked for him.

I was also considering trying the the -zapwallettxes startup option on my old wallet, but "abandon transaction" with a new wallet sounds much more appealing if it indeed works on transactions initiated before the wallet upgrade.

And just to be sure since I haven't upgraded in years - to upgrade to the new Bitcoin Core on my Windows 7 machine I just run the installer downloaded from bitcoin.org?

Thanks!

You don't need to run that command now, just right click the transaction in question and choose the "Abandon transaction" option.

Yes. You may need to start Bitcoin Core with -upgradewallet however in order to make sure that everything works.


P.S. I split your question into its own thread. Please do not hijack someone else's thread with your own questions and issues even if you think the problem is the same.

If the transaction is still stuck I'd suggest you try an accelerator. The one I've used in the past is viabtc which can be found here: https://www.viabtc.com/tools/txaccelerator/

The reason these transactions typically don't get sent is because the fee is too low. My understanding as to how the accelerator works are that viabtc will put your transaction into a block and mine it for you. This can be useful if you sent a transaction for a purchase and didn't use an appropriate fee, or if someone sent you bitcoin and didn't use an appropriate fee.

Have a great day!
