Linux Mint 15 Olivia source list
linux mint;apt
You have a bundle of problems, so lets start for the most important:Your version of Mint is obsolete. There are some improvements in newer versions of apt, found in recent version of Linux Mint that prevent problems like this:E: Encountered a section with no Package: headerE: Problem with MergeList /var/lib/apt/lists/security.ubuntu.com_ubuntu_dists_raring-security_main_i18n_Translation-enE: The package lists or status file could not be parsed or opened.There are duplicated entries in your sources.list files. Search them and remove them. I'm seeing two http://security.ubuntu.com/ubuntu/ raring-security entries.Since you are using an obsolete version of Mint, and Mint use Ubuntu repositories mostly, you get several Not Found errors since they where removed from the servers to other servers. Update or change all the security.ubuntu.com and archive.ubuntu.com lines to old-releases.ubuntu.com.There are three GPG errors, one BADSIG that is caused due Canonical's revocation of key, and two no available signatures since you didn't add them. Fix that also.Your package list cache is a mess. I would remove it entirely with:sudo rm /var/lib/apt/lists/*And then update the package list. This should be done after you have fixed all the previous issues, otherwise is likely that its effect will be negligible, but it should fix the Reading package lists... Error! message.Remember, most of these issues are just blown away if you reinstall (since Linux Mint doesn't offer a reliable upgrade path) your OS anew with a recent version of Mint.
