It looks like your data on disk was corrupted. Thus, -reindex fails to find a valid block in blk00000.dat. What kind of hardware are you running on?

/home/home/.bitcoin/chainstate :no_mouth: , is it home user? & are you using network storage mount somewhere?

I am running into this same problem when trying to generate genesis block in RavenProject/Ravencoin (bitcoin fork)

I wish I had more to add but I am stumped.

You might want to check your hardware for defects.

memtest86 to check your RAM
to check the CPU behaviour under load, use linpack or Prime95
to test your storage device use smartctl or CrystalDiskInfo

I am doing this on a fresh install on a fresh Ubuntu 16.04.4 x64 droplet. Will check your suggestions, though.

RavenProject/Ravencoin (bitcoin fork) @lukepighetti Please, this is not an altcoin support channel.
