E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

hello all, I resolved it. I changed the software sources to download from the main server.
system > administration > software sources > select download from main server.
I think the other servers don't have all the necessary files to upload. I don't know what's the point to maintain such a server where they don't upload the files in time and cause problem to newbies like us :(
