transaction verification failed on monero-blockchain-import

Question

I am new to monero. I'm running version:

Monero 'Boron Butterfly' (v0.14.0.2-release) on Arch Linux

I started with the following steps:

wget -c --progress=bar https://downloads.getmonero.org/blockchain.raw
/usr/bin/monero-blockchain-import --data-dir /path/to/monero --input-file blockchain.raw

After running for many hours, it failed with this message. I'm showing just the last few lines of output:

Answer 1

This is a known bug, thought fixed in master, and restarting the import will continue just fine. If it does not, then it's time to report the bug to https://github.com/monero-project/monero
