I used google compute engine from Google Cloud Platform , and I want to store my data in googles storage, so I used the gsutil to send data from compute engine to google storage
Before i updated python2.6.6 to python2.7, gsutil was working fine. But after update to 2.7
it took me lots of time...
P.S I use CenOS6.7
I had exactly the same problem, and I solved it by removing boto settings:
sudo rm -f /etc/boto.cfg
