Excuse me here if I am asking a question already asked, but im having some problems when entering "sudo apt-get update" in terminal. I get these errors; This is derived from problems with update manager so I thought id try the terminal to update. I have version 8.04.1 W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used.GPG error: http://wine.budgetdedicated.com hardy Release: The following signatures were invalid: BADSIG 58403026387EE263 Scott Ritchie <scott@xxxxxxxxxxxxx> W: GPG error: http://falcon.landure.fr hardy Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 1CA3E3239FA7DC39 W: Failed to fetch http://wine.budgetdedicated.com/apt/dists/hardy/Release W: Some index files failed to download, they have been ignored, or old ones used instead.
