This question already has an answer here:
I am using Ubuntu 12.04, 64 bit virtual machine within a company network which obviously has firewalls. When I try to run sudo apt-get update or sudo apt-get update --fix-missing I get this error:
(Assume archive.ubuntu.com before ever _ubuntu)

They have been ignored, or old ones used instead.
I have tried removing
/var/lib/apt/lists as mentioned in other posts and it does not work. The actual problem is that the company firewall is corrupting the download traffic which gives the hash sum mismatch. This is a known issue as seen here as well:
So, is there any work around to update packages for me and many Ubuntu users behind company firewalls?
