is actually obsolete and it isn't in your sources.list
Please check if there is an obsolote sources.list in
/etc/apt/sources.list.d
and in case move it.

No problem to fetch urls here.
Proxy enabled?

You also have some google repo enabled someplace, check in software sources too to make sureits not in there.

there are 2 files in the /etc/apt/sources.list.d directory, google-chrome.list and google-chrome.list.distUpgrade, both have the line "deb http://dl.google.com/linux/deb/ stable main" and nothing else, as for a proxy no, I do not have one. I ran the commands you gave me, the error message changed a little but still pops up whenever I try to update:
W: GPG error: http://us.archive.ubuntu.com karmic Release: Unknown error executing gpgv
W: GPG error: http://security.ubuntu.com karmic-security Release: Unknown error executing gpgv
W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used.GPG error: http://dl.google.com stable Release: Unknown error executing gpgv

W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used.GPG error: http://us.archive.ubuntu.com karmic-updates Release: Unknown error executing gpgv

W: Failed to fetch http://dl.google.com/linux/deb/dists/stable/Release

W: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/karmic-updates/Release

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

ok, read over your links and found that just taking out the library completely fixes the problem

Thanks for the help everyone

Thanks Sam, that solved my question.
