I have been unsuccessfully trying to sync the blockchain for the past 5 days using the latest 32bit Linux Monero Core on Tails live USB. I followed the instructions in the Tails/Tor post on /r/Monero to the letter and everything works until it reaches around 1200700 blocks then I keep getting 'Segmentation fault' message. I tried placing the data directory on different HDD's and SSD's and keep encountering the same problem. Would greatly appreciate any help as I'd love to have a node running and support the Monero community.
Please update your monerod to the latest version 0.10.1.0 Wolfram Warptangent.
There has been a hard fork to introduce RingCT transactions at block 1220517 and if you are running an old version, it will not be able to sync with the network.
