I decided to user kernel-source-2.6.11 as a test case, because I am sure I have not downloaded it since the update. Before starting the download, I said "cp kernel-source-2.6.11_2.6.11-5_all.deb kernel-source-2.6.11_2.6.11-5_all.deb-orig" in both /var/cache/apt-cacher/packages and /headers, to save the current versions I have. Then on one of the clients, I said "apt-get install kernel-source-2.6.11", which resulted in an external download, and the following files in the error.log: (removed the time-stamps) ------------------------------------------------------------------ debug: called with /ftp2.de.debian.org/debian/pool/main/k/kernel-source-2.6.11/kernel-source-2.6.11_2.6.11-5_all.deb debug: new filename with just basename: kernel-source-2.6.11_2.6.11-5_all.deb debug: looking for /var/cache/apt-cacher/packages/kernel-source-2.6.11_2.6.11-5_all.deb debug: HIT debug: open /var/cache/apt-cacher/packages/kernel-source-2.6.11_2.6.11-5_all.deb debug: file is not complete debug: fetcher: try to pick up http://ftp2.de.debian.org/debian/pool/main/k/kernel-source-2.6.11/kernel-source-2.6.11_2.6.11- 5_all.deb debug: Executing /usr/bin/curl -D- --stderr /dev/null http://ftp2.de.debian.org/debian/pool/main/k/kernel-source-2.6.11/kerne l-source-2.6.11_2.6.11-5_all.deb debug: starting to return /var/cache/apt-cacher/packages/kernel-source-2.6.11_2.6.11-5_all.deb debug: no header yet... debug: read 0 bytes debug: read 65536 bytes debug: wrote 65536 bytes (repeating many times)... debug: read 4096 bytes debug: wrote 4096 bytes debug: read 0 bytes debug: pick up http://ftp2.de.debian.org/debian/pool/main/k/kernel-source-2.6.11/kernel-source-2.6.11_2.6.11-5_all.deb as /va r/cache/apt-cacher/packages/kernel-source-2.6.11_2.6.11-5_all.deb, return code 0 debug: fetcher exiting debug: read 65536 bytes debug: wrote 65536 bytes debug: read 65536 bytes debug: wrote 65536 bytes debug: read 65536 bytes debug: wrote 65536 bytes debug: read 24196 bytes debug: wrote 24196 bytes debug: read 0 bytes debug: exit (file completed) * * * So, it seems apt-cacher decided the file I already had was incomplete. Now I diffed the old and new header and package files, and the package itself is exactly the same as before, and the diff output for the header file is this: --- kernel-source-2.6.11_2.6.11-5_all.deb-orig 2005-06-01 22:56:17.867888288 +0200 +++ kernel-source-2.6.11_2.6.11-5_all.deb 2005-06-01 22:56:35.738171592 +0200 @@ -1,11 +1,9 @@ HTTP/1.1 200 OK -Date: Tue, 17 May 2005 21:54:35 GMT +Date: Wed, 01 Jun 2005 20:56:38 GMT Server: Apache/2.0.53 (Debian GNU/Linux) Last-Modified: Tue, 17 May 2005 05:47:29 GMT ETag: "29c8094-2294e84-e8677e40" Accept-Ranges: bytes Content-Length: 36261508 -Keep-Alive: timeout=15, max=100 -Connection: Keep-Alive Content-Type: application/x-debian-package -------------------------------------------------- Subsquent requests for the same file are now served from the cache. * * * So, the question is, why did apt-cache think the file is imcomplete? It was not. Is there some meta-info, which was not imported properly from the old cache? > How did you import the old cache? Here is what I did: In my old config /var/cache/apt-cacher was a link to an other directory (let's name it /local/apt-cache for now.) After upgrading apt-cacher, I discovered that the symlink is gone, and there is a new directory instead. In the new directory, I found the 5 new subdirectories. (headers, import, packages, private, tmp.) I found the original archive /local/apt-cache untouched. (At this point, I sligtly wondered what would have happened to my old data if /var/cache/apt-cacher haooebed to be a real dir, not of a symlink, but then I decided that I don't care, let's just make it work.) For a first step, I pulled a few packages via the new system, without importing anything from the old one. They appeared in /packages, as they should. Then I copied a few "mixed deb" file from /local/apt-cache to the new /var/cache/apt-cacher directory, and called /usr/share/apt-cacher/apt-cacher-format-transition.pl /var/cache/apt-cacher to see if it goes OK. It did: the debs I copied there disappeared from /var/cache/apt-cacher, and the demuxed package and the header appeared in the right subdirectories. So it seemed fine. * * * Here came the tricky part: Since the old /local/apt-cacher directory and the new /var/cache/apt-cacher directory were an different partitions, and I did not feel like copying the >9000 .deb, I did the following: a) I removed everything except the mixed deb files (namely, all subdirectories, packages/release and source files) from /local/apt-cache. b) I moved the new subdirectories from /var/cache/apt-cacher to /local/apt-cache c) I removed the (empty) /var/cache/apt-cacher directory d) I simlinked /local/apt-cache to /var/cache/apt-cacher. * * * (I believe the above four steps are equivalent to copying all the mixed up debs to the new directory). I called /usr/share/apt-cacher/apt-cacher-format-transition.pl /var/cache/apt-cacher again. It run for a while, and converted my ~9500 packages nice. At the end, all mixed-up debs were gone from /var/cache/apt-cacher (now a simlink to /local/apt-cache, like with the old version), and the new demuxed packages appeared in the right place. It seemed to be fine. (Sorry for the lengthy answer, but I did not want to omit anything I did that might have broken the thing.) * * * > Have you nuked old / irrelevant files? If you mean the old mete-data (like the subdirectories in /local/apt-cache), that as I have written above, I have. > How many files are in /var/cache/apt-cacher/private/ ? 982. (And 10013 in /var/cache/apt-cacher/packages.) * * * One more (offtopic) thing: (maybe I should have filled a separate bugreport, but I guess this is a more simple way): At line 27-28, /usr/share/doc/apt-cacher/README.Debian says this: "to use apt-cacher with apache2, symlink the file /etc/apt/apt-cacher.conf to /etc/apache2/conf.d/apt-cacher.conf and restart apache2." Now I have never seen "/etc/apt/apt-cacher.conf". Should not that been /etc/apt-cacher/apache.conf instead? For an inexperienced user, this might be quite misleading...) * * * Best wishes: Kristof -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
