Cydia will not update

When I rename, I just put a 1 at the beginning of the file/directory.

 If you find the filename "lock" in any directory, then rename it.

Rename the following files/directories in /private/var/root/Library/Caches/com.saurik.Cydia
ApplicationCache.db
LocalStorage
SDURLCache
com.apple.opengl
lock

Rename the following files/directories in /private/var/cache
apt

Rename the following files/directories in /private/var/lib/cydia
metadata.cb0
metadata.plist

Check /private/var/lib/dpkg for the filename lock
rename lock if it exists

*Move the following files in /private/etc/apt/sources.list.d to a directory where you can find them, if needed, because I never believe in "deleting" until everything works.
cydia.list

*Move the following files in /private/var/lib/dpkg/info to a directory where you can find them, if needed, because I never believe in "deleting" until everything works.
cydia.list

Cydia will not update
Cydia will not refresh
Cydia will not reload
