Since yesterday I've been trying to run

apt-get update

unsuccessfully in Ubuntu instances I am creating on the EC2.

In specific I've been getting these errors:

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

root@ip-10-168-230-63:/etc/apt# 

I did run

apt-get update --fix-missing

without any luck.

Any ideas?

I have done these tasks many times on Ubuntu Linux instances running in the AWS EC2 without any problems.
Thanks in advance for your help!
