Question

s3cmd SignatureDoesNotMatch

Problem

When I try to use s3cmd it exits with the following error:

ERROR: S3 error: 403 (SignatureDoesNotMatch)

Attempted Solutions

I have tried regenerating my keys as other similar questions suggested.

Context

I am using s3cmd version 2.0.2.

My s3cmd configuration has the following relevant options:

[default]
access_key = REDACTED
access_token = REDACTED
...
host_base = sfo2.digitaloceanspaces.com
host_bucket = %(bucket)s.sfo2.digitaloceanspaces.com

The s3cmd command I am trying to run is:

s3cmd put foo.txt s3://SPACE/ -c ./s3cmd-cfg

The space I am trying to access is in SFO2.

Hey friend,

I do not consider myself an expert on s3cmd, and I realize that you already have a configuration file, but can you try setting up the configuration specifically by the steps we’ve outlined here?

https://www.digitalocean.com/docs/spaces/resources/s3cmd/

It may be some very small difference that is made by using those steps.

same error:

s3cmd --version
s3cmd version 2.2.0

New settings:
  Access Key: xxxxxxxxxx
  Secret Key: xxxxxxxxxxxx
  Default Region: fra1
  S3 Endpoint: fra1.digitaloceanspaces.com
  DNS-style bucket+hostname:port template for accessing a bucket: %(bucket)s.nyc3.digitaloceanspaces.com
  Encryption password: secure_password
  Path to GPG program: /usr/bin/gpg
  Use HTTPS protocol: True
  HTTP Proxy server name:
  HTTP Proxy server port: 0

Test access with supplied credentials? [Y/n] Y
Please wait, attempting to list all buckets...
Success. Your access key and secret key worked fine :-)

Now verifying that encryption works...
Success. Encryption and decryption worked fine :-)

Save settings? [y/N] y
Configuration saved to '/home/name/.s3cfg'

s3cmd mb s3://spacename3
ERROR: S3 error: 400 (XAmzContentSHA256Mismatch)

I did follow the setting documentation: https://docs.digitalocean.com/products/spaces/reference/s3cmd/

This is resolved by adding to the s3cfg file: signature_v2 = True
