i running django in python virtual environment(virtualenv). django website served apache2 amazon ec2 instance(ubuntu 16.04). use boto3 module write amazon s3.

i installed awscli , ran aws configure , set aws access keys correctly. ( know configured correctly, because $ aws s3 ls returns correct lists of s3 buckets.)

however, when try write objects s3 django application, fails producing error described in title.

i moved new instance , started using python virtual environments. before that, used work fine. have read questions on , docs aws. below stack trace.

i figured out reason getting error. posting answer in case else encounters issue.

tl;dr : aws config files did not live in apache's home directory

the django app running under user www-data(apache2). when configured credentials using aws configure, settings stored in .aws/config file.

now problem was.

the .aws/configure file stored in my home directory , not in home directory of www-data(apache2),which /var/www default. when django app called boto3 module, module looking config file in /var/www/.aws/config files in /home/ubuntu/.aws/config.

simply copying relevant files /var/www/ fixed problem me.
