Running Boto3 on Ubuntu 18.04 - python-3.x

Question

I cannot run boto3 on Ubuntu 18.04 (AWS), initially I thought the code was broken but it might actually be the installation itself?
ubuntu#ip-172-30-10-199:~$ sudo -H pip3 install boto3
Requirement already satisfied: boto3 in /usr/lib/python3/dist-packages
ubuntu#ip-172-30-10-199:~$ sudo -H pip3 install botocore
Requirement already satisfied: botocore in /usr/lib/python3/dist-packages
ubuntu#ip-172-30-10-199:~$ python3 --version
**Python 3.6.9**
ubuntu#ip-172-30-10-199:~$ sudo apt-get install python3-boto3

Running the code.

I do have a file ~/.aws/credentials containing the respective keys. I do use these same keys to access the bucket from my laptop (S3 Browser).

Answer 1

I manage to find the answer.
Somehow it was related to S3 permissions, instead of using Key/secret e manage to give S3 Fullcontrol role to my EC2 and it worked like a charm.
Mea culpa, I think the error message could be also more informative. Please learn from my mistake :-)
