Public bug reported: Today I made the decision that, since I have three machines that run Kubuntu, I should create local repositories of all of my recently- installed Edgy and Dapper packages, in order to save the Ubuntu team a little bit of bandwidth. In the process, I discovered that Edgy seems to be unwilling to use my local repository, while the Dapper box is content with the idea.
In /etc/apt/sources.list, one can find the following line, which would normally be uncommented, enabling the Universe repository: deb http://us.archive.ubuntu.com/ubuntu edgy universe If I enable this line (and do an 'apt-get update'), apt-get then refuses to use my local repository. However, if I disable that line and update again, apt-get is quite happy to use my local repository. Both the Edgy and Dapper repositories were created, by root, as follows: 1. Make a directory someplace to store the .deb files. I chose /data/Software/Edgy and /data/Software/Dapper, which sit on an NFS share on my fileserver. Permissions are 755 for the directories and their parent, and root owns them all. 2. Using the Edgy machine, move all .deb files from /var/cache/apt/archives over to the new Edgy repository directory. Do the same on the Dapper machine, to populate it's repository. Permissions are 644 on all files, and root owns everything. 3. On both machines, add the following line to the beginning of your usual /etc/apt/sources.list : deb file:///data/Software/Edgy ./ 4. Do an 'apt-get update' on both machines to make the changes take effect. 5. Run the following script (without the horizontal lines of course) to create Edgy's Packages.gz file: ------------------------ #!/bin/bash pushd . cd /data/Software/Edgy rm /data/Software/Edgy/Packages.gz cp /var/cache/apt/archives/*.deb /data/Software/Edgy rm /var/cache/apt/archives/*.deb dpkg-scanpackages ./ /dev/null |gzip -9c > /data/Software/Edgy/Packages.gz apt-get update popd ----------------------- The script for the Dapper machine is constructed the same way, and can be found at the end of this message. You'll notice that, aside from the odd way I chose to 'move' the files to my repository, the last 'real' command performs another 'apt-get update', to put the newly-created Packages.gz file into use. To test whether or not my local repository was being used, I did the following simple test on both machines: 1. apt-get remove xine-ui (could be any other package with few or no programs that require it) 2. Verify that /var/cache/apt/archives does not contain a xine-ui package of any sort. 3. Verify that /data/Software/Edgy contains the exact package also present on the Ubuntu server. 4. apt-get install xine-ui I also checked using this command: apt-get install --print-uris xine-ui The above procedure agrees with the result of this last apt-get command - disabling the aforementioned line in sources.list allows my local repository to be used on the Edgy box, while the Dapper box seems to work fine with that line enabled. It almost seems like the Ubuntu server in question is sending something down the line telling apt-get to, essentially, override and ignore the local repository for the Edgy machine. After some fairly thorough searching and comparing both machines' configurations, I found only two differences in the way apt is configured: 1. The Edgy box has a file named /etc/apt/apt.conf.d/01ubuntu which is not present on the Dapper box at all, and which contains the following (minus the horizontal lines): ----------------------------- APT { NeverAutoRemove { "^linux-image.*"; "^linux-restricted-modules.*"; }; Install-Recommends-Section "metapackages"; }; ----------------------------- 2. The Dapper box has an /etc/apt/apt.conf , which is not present at all on the Edgy box, containing a single line: Acquire::http::Proxy "false"; Out of fear of breaking my system, I have explicitly avoided altering the contents of any apt configuration file other than /etc/apt/sources.list. Otherwise, the two machines' apt configurations appear to be identical, save for necessary differences in the two machines' /etc/apt/sources.list files.
