Solution

I've resolved it. It seems that you added more than one source entries in /etc/apt/sources.list. I guess more than one entry will make apt command confused, likely get header from one source then get packages from another, and the package size may not equal to the one defined in header. Edit the file and left only one source entry worked for me. Hope this helpful
