How To Create An Ubuntu Repository Mirror on Ubuntu 8.04 June 10th, 2008 Christer Edwards Leave a comment Go to comments If youre new here, you may want to subscribe to my RSS feed. Thanks for visiting! I was discussing the creation and maintenance of an Ubuntu repository mirror in IRC today and realized that I haven’t blogged about how to do that. Its funny sometimes how topics pop up, and something I’ve been using for months never made it onto the blog. In any event, below I’ll outline how to create your own Ubuntu repository mirror–great for consolidating and saving bandwidth for multiple machines! Creating the Mirror To create an Ubuntu repository mirror we’ll use the apt-mirror tool. This can be installed by issuing the following command or clicking the link: sudo aptitude install apt-mirror Once this package is installed you’ll need to configure a few items: 1. Where will your mirror be stored? 2. How aggressive will you be about downloading? 3. What do you want to mirror? To edit these values you’ll want to edit the /etc/apt/mirror.list file. I’ve displayed mine below, and broken it down into the three main sections. Where Will Your Mirror Be Stored? I’ve configured my apt-mirror to be stored on an external USB drive. This is defined via the line: set base_path /media/gurudisk/UBUNTU/MIRROR This overrides the default value, which stores the data in /var/spool/apt. How Aggressive Will You Be About Downloading? This title may be a bit misleading but this is the way I think about it. Technically its the number of download threads you want to use. The higher the number, the more threads, the faster its done. This will depend on your1 de 6 21-06-2011 14:51

This will depend on your bandwidth connection though. On my home DSL I can’t put this number any higher than 2. In faster locations you’ll be able to put the number much higher. Your milage may vary. set nthreads 2 What Do You Want To Mirror? Now, the most important part, is what do you actually want to mirror? The syntax for this section is pretty simple. It looks just like a normal sources.list entry, but for each address you want to mirror. Here is an example of my entry for Ubuntu 8.04, i386: # Ubuntu 8.04 "Hardy" i386 deb-i386 http://archive.ubuntu.com/ubuntu hardy main restricted universe multiverse deb-i386 http://archive.ubuntu.com/ubuntu hardy-updates main restricted universe multiverse deb-i386 http://archive.ubuntu.com/ubuntu hardy-backports main restricted universe multiverse deb-i386 http://archive.ubuntu.com/ubuntu hardy-security main restricted universe multiverse deb-i386 http://archive.ubuntu.com/ubuntu hardy-proposed main restricted universe multiverse If you want amd64 bit mirrored you might add entries like this: # Ubuntu 8.04 "Hardy" amd64 deb-amd64 http://archive.ubuntu.com/ubuntu hardy main restricted universe multiverse deb-amd64 http://archive.ubuntu.com/ubuntu hardy-updates main restricted universe multiverse deb-amd64 http://archive.ubuntu.com/ubuntu hardy-backports main restricted universe multiverse deb-amd64 http://archive.ubuntu.com/ubuntu hardy-security main restricted universe multiverse deb-amd64 http://archive.ubuntu.com/ubuntu hardy-proposed main restricted universe multiverse Notice that I’m mirroring main, restricted, universe and multiverse plus the security, proposed, backports and updates sections. This gives me a complete mirror of everything that would normally be available. If you don’t want/need proposed or backports, etc you can simply remove those lines. If you want to be able to use your mirror to support network based installations you’ll also need to add the following (depending on your architecture):2 de 6 21-06-2011 14:51

How To Create An Ubuntu Repository Mirror on ... http://ubuntu-tutorials.com/2008/06/10/how-to-cr... you’ll also need to add the following (depending on your architecture): deb-amd64 http://archive.ubuntu.com/ubuntu hardy main main/debian-installer deb-amd64 http://archive.ubuntu.com/ubuntu hardy restricted restricted/debian- installer deb-amd64 http://archive.ubuntu.com/ubuntu hardy universe universe/debian- installer deb-amd64 http://archive.ubuntu.com/ubuntu hardy multiverse multiverse/debian- installer or deb-i386 http://archive.ubuntu.com/ubuntu hardy main main/debian-installer deb-i386 http://archive.ubuntu.com/ubuntu hardy restricted restricted/debian- installer deb-i386 http://archive.ubuntu.com/ubuntu hardy universe universe/debian- installer deb-i386 http://archive.ubuntu.com/ubuntu hardy multiverse multiverse/debian- installer Basically just add the sources.list entry to this file for anything you want to mirror. I also mirror Medibuntu and a few PPA locations. It sure makes for faster installation when I am able to use the LAN as compared to the public tubes. To keep your mirror updated activate the cron entry in /etc/cron.d/apt-mirror. By default it will try to update your mirror at 4:00am, and it is disabled. To activate it simply uncomment the line and change the 4 to the preferred hour of your choice. Enjoy! Update: My mirror, including main, restricted, universe, multiverse, -proposed, -backports, -security, Medibuntu and the network installation sections takes up 37G. I do mirror i386 and amd64, so if you just need one architecture you could half-that.

However, note that the default ubuntu config file is /etc/apt /mirror.list, so you should run the update: apt-mirror -c /etc/apt/mirror.list The config file name in the original article was wrongly specified as apt-mirror. Ian. 2. Ian Barton June 23rd, 2008 at 01:54 | #2 Reply | Quote Whoops… made a mistake myself:) The correct command is: apt-mirror /etc/apt/mirror.list Ian. 3. Nicco June 23rd, 2008 at 08:24 | #3 Reply | Quote So after creating the repository mirror how does one access it from the client computers? -Thank You 4. Christer Edwards June 23rd, 2008 at 19:56 | #4 Reply | Quote @Nicco – simply update the clients to point to something like: deb http://ip.address.of.mirror/ubuntu hardy main restricted, etc.. It’ll require that the mirror machine has some web server installed (apache, lightty, etc). Otherwise its the same format as normal, just using your local IP vs the public address. 5.

DP June 30th, 2008 at 17:25 | #6 Reply | Quote Hi Christer, I’m a little unclear about the syntax in the mirror.list file. Is it necessary to list the d-i packages as: deb-i386 http://archive.ubuntu.com/ubuntu hardy main main/debian- installer ? Can the debian-installer branches be listed as: deb-i386 http://archive.ubuntu.com/ubuntu hardy main/debian-installer Or just incorporated into the first set? Also, I’ve found that mirroring the d-i packages under updates and security breaks my network install: ie. placing: deb http://archive.ubuntu.com/ubuntu hardy-security main/debian-installer Resulted in a broken install. I had to clean and and purge the mirror. Any idea why this is the case? Thanks for the tutorial. -DP 7. Johnnie August 21st, 2008 at 18:52 | #7 Reply | Quote I am doing your steps into Hardy Heron but I can´t do than it works. I give me an error from ../bin/apt-mirror I am not sure what can be but is difficult to me find the solve. Thxs5 de 6 21-06-2011 14:51

Bart October 31st, 2008 at 14:29 | #8 Reply | Quote I found a “low-tech” solution for when setting a local mirror is too much for a few computers: http://nxadm.wordpress.com/2008/10/31/home-network-low-tech-trick- for-a-very-fast-ubuntu-release-upgrade/ (BTW: I set up your solution at work and I am the hero ) 9. Clinton February 11th, 2009 at 18:20 | #9 Reply | Quote I have configured a machine with the mirror but do I need to update the mirror list and remove the http entries and simply just add the ip address of the server that mirrors all the updates? 10. Zzypty Zzyp March 12th, 2009 at 03:59 | #10 Reply | Quote Hi! If the amount of memory allotted on a particular server is small (less than the 37GB or 18gB you mentioned), what are the directories that can be excluded without causing too much of a flutter? 11. adrianherr June 12th, 2009 at 09:45 | #11 Reply | Quote Hi, I am new to the forum. Please can you help me with a apt-mirror issue. I have three repositorys but I no longer need one of them. How do I remove it without re-downloading the once I want? Regards.6 de 6 21-06-2011 14:51
