can't sync database.. always different error messages

[AnCapFree]

I was getting

"error: a fatal internal error occurred. see debug.log for details" and also

MinGW Runtime Assertion

Assertion failed!

Program: C:\Program Files\Bitcoin\bitcoin-qt.exe
File: Main.cpp Line 1789

Expression: hashPrevBlock == view.getBestBlock()




I've tried reindexing but now it just showed me "error: a fatal internal error occurred. see debug.log for details"


The debug.log but I've taken this from the end when it appears that things started to go to hell

It looks like one of the blocks is corrupted, so you will actually need to resync. The easiest way is to just delete the blocks folder in the data directory. But that takes the most amount of time. You could try to find which blk.dat file contains the problem block, which in your case, looks like 303256. If you can figure out which blk.dat file it is in, then delete that file and all of the higher number files after it. You will still need to download some blocks, but not all of them. A reindex will also be required if you do that.

You should also disable UPnP[1] for now.

and how would I find the file that contains that block?

[achow101]

and how would I find the file that contains that block?

Very carefully

Honestly, it would just be easier to delete the blocks folder and let it do a full resync.

that will take me like 3 days and I want to spend now.

I'm using bitcoin-cli dumpprivkey myPublicAddres so that I can use my coins in a lightweight wallet but I'm getting:

error: couldn't connect to server


My bitcoin.conf is

server=1

rpcuser=generated_by_armory

rpcpassword=slclsnlklkfqndmsnnswliqnsonlqsln

Do you have Bitcoin Core running? It needs to be running. If it isn't, set it to reindex and then do that command before it exits out.

oh great

Now, I've deleted all the blocks and uninstalled and reinstalled thew core (0.11) and now it can't open, it says:


MinGW Runtime Assertion

Assertion failed!

WTF
