You’ll probably want to go to the filecoin discussion board if there is one, or the filecoin slack.
I have had this issue, and there seems to be any number of possible reasons such as:
- Invalid version of lotus (make sure you are on v0.1.6)
- Janky internet connections
- Improperly downloaded data
- Previously existing checksum data
If you are still having issues, I maintain a docker image for the lotus node (non miner nodes) here https://hub.docker.com/repository/docker/rtradetech/lotus-node that you can try running. If you need a copy of the checksum params I might be able to add the one I use to IPFS and send you the link.
