info:   481806 blocks,  295.312 MegaAddrs ,                                             
fatal: failed to locate upstream transaction23secs, mem = 0.000 Gig           
Aborted

Please don't tell me I have to hack yet another abandoned github project...

+1 have same issue . any update ?

info: 481823 blocks, 295.351 MegaAddrs ,
fatal: failed to locate upstream transaction

I found a solution to this problem. It is necessary to synchronize blockchain with the old bitcoin-core. I used the version of bitcoin-core-0.11.2 (synchronize with the block that causes the error)

[ghost]

so you mean, i should install bitcoin-core-0.11.2 and do rescan on whole blockahain files ?

[Migelh]

You need to remove the blocks on which the error appears

example:

info: 481806 blocks, 295.312 MegaAddrs,
fatal: failed to locate upstream transaction23secs, mem = 0.000 Gig
Aborted

then you need to delete all blocks above 480000, and make synchronization bitcoin-core-0.11.2

thanks, i ll try that.

"then you need to delete all blocks above 480000, and make synchronization bitcoin-core-0.11.2"
How do I find out which file the block is in?

[ghost]

try
cd ~/.bitcoin/blocks

ls -lah

try this
if you have been running full node, from before segwit , then check date https://blockchain.info/block/000000000000000000cbeff0b533f8e1189cf09dfbebf57a8ebe349362811b80

delete all blocks files which are created after 2017-08-23

else if you just installed

try removing last 10 files.
if does nt work, try more last 10 files.
