Detailed Description
An item that is responsible for downloading the meta-index {{{ file (i.e., Release) itself and verifying its signature.
Once the download and verification are complete, the downloads of the individual index files are queued up using pkgAcqDiffIndex. If the meta-index file had a valid signature, the expected hashsums of the index files will be the md5sums listed in the meta-index; otherwise, the expected hashsums will be "" (causing the authentication of the index files to be bypassed).
The documentation for this class was generated from the following files:
- apt-pkg/acquire-item.h
- apt-pkg/acquire-item.cc
