Hi, Let me summarize:
There are at least 1 bug and 1 concern. * bug: support for deb.debian.org * concern: truncated InRelease file As for the bug of deb.debian.org, resolution can be: * root cause fix: Support redirect (SRV record?) so apt-cacher-ng works as expected. - See http://deb.debian.org/ * work around: Add cdn-fastly.deb.debian.org to /usr/lib/apt-cacher- ng/deb_mirrors.gz and document to recommend to use cdn- fastly.deb.debian.org instead of deb.debian.org - Without adding cdn-fastly.d.d.o to this file, debs are not placed to the debian package cache and also initialization code to generate /etc/apt-cacher-ng/backends_debian has problem.. - The same work around needs to be added to security and volatile ... (If Ubuntu mirror URL uses the same kind of cdn, you may wish to support them too.) - Please note deb.debian.org is becoming installation default these days. If your apt line list normal old-fashoned mirror site such as ftp.de.debian.org, you may not have as much problem. As for the concern of truncated InRelease, this happens with cdn- fastly.deb.debian.org with fesh new cache. If this is not expected behavior, please think about fixing this. Very reproduceble. For work around, run apt-get update multiple time until it is neat shape. Thanks for your attention. Osamu
