The log is correct. I guess mc for amd64 is buggy. The binary release is updated today April 1 and something went wrong. Now that s3-tests shows no degradation, I can put off the bug tag.

[akiradeveloper]

According to the manual, ls alias is the valid command

EXAMPLES:
   1. List buckets on Amazon S3 cloud storage.
      $ mc ls s3

[akiradeveloper]

I removed the first line of "add buckets" test and it turned to green.

The thing is amd64's mc can't list when there is no buckets.

I should reproduce this issue and feedback to upstream
