"error: failed to verify the checksum of [crate]"

[lucypero]

When I try to build a crate that uses a crate from my registry, I get this strange error:

error: failed to verify the checksum of `lucylib v0.1.0 (registry `lucy-registry`)`

What could it be? The checksum in the index is correct.

Is there a checksum in your lockfile?

[lucypero]

on the crate that is using the crate? yes, and it is correct

Unfortunately I don't have any ideas on what could be the problem.

The error is generated when the SHA256 checksum of the file downloaded over the network does not match what is listed in the index. You can check that the hash of the .crate file is the same as what is in the index. You may also need to delete cargo's cache (in ~/.cargo/registry) if you have been modifying the index (cargo generally assumes existing entries are immutable).

If you have a reproduction, I can perhaps help, otherwise this issue may need to be closed.
