Package: apt Version: 2.9.10 X-Debbugs-CC: ogn...@ognyankulev.com
Each `apt update` downloads fully the specified mirrorlist file, instead of using If-Modified-Since: HTTP header to skip downloading the same content.
Comparing it to other downloads, mirrorlist files are not downloaded first into partial/ but anyway apt treats them as partial and requests continuing the "partial" download. When this fails, the file is downloaded completely. The expected behavior is requests to have If-Modified-Since: HTTP header like other already downloaded files. A sample session follows:
