Apt-get update gives an error

[PeterTaps]

Folks,

I am running Ubuntu 11.04. When I run "apt-get update," I get the following error:

Err http://us.archive.ubuntu.com natty-updates/universe Translation-en
Bad header line [IP: 91.189.92.177 80]
W: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/natty-updates/universe/i18n/Translation-en Bad header line [IP: 91.189.92.177 80]

E: Some index files failed to download. They have been ignored, or old ones used instead.

I have run updates in the past. I don't recall seeing this error.

Is there a way to fix this problem? Or, is there a problem with the archive server that perhaps will go away in a few hours?

Thank you in advance for your help.

Regards,
Peter

I have noticed that the repos have been flakey today. You might try changing to a different server.
