Unexpected 'certfile' argument

[dmenig]

New error on my gccp instances getting data from s3 bucket.

user_name@instance~$ s4cmd -c32 get -r s3:/my-bucket/my-data/
[Exception] __init__() got an unexpected keyword argument 'cert_file'
[Thread Failure] __init__() got an unexpected keyword argument 'cert_file'

Never seen this before

Adding -p ~/.s3cfg doesn't solve it

Got same exception on Ubuntu Bionic. Strangely it seems, that neither of s4cmd, python-boto3 or python-botocore packages were upgraded since previous successful use, nor pip-version are installed on the system. Reproduced with just:

$ s4cmd ls
