Selfhosted

jigdo the entire repositories of your Debian's favorite architectures for the win.

And... you can also convert the ISO files into an hosted repository in your network using Apache:

apt install apache2 build-essential mkdir /var/www/html/packages

Now, create additional directories under /var/www/html/packages/ to save packages depending upon your system’s architecture. For example, create a directory “amd64″. You can keep multiple directories and serve packages to different architecture systems at the same time.

mkdir /var/www/html/packages/amd64

Copying all DEB files from Debian installation media

Mount the first CD/DVD and copy all .deb packages to /var/www/packages/amd64/ directory from your CD/DVD.

mount /dev/cdrom /media/cdrom find /media/cdrom/pool/ -name "*.deb" -exec cp {} /var/www/html/packages/amd64 ;

After copying all deb files, unmount the first DVD using the following command.

umount /media/cdrom

Again mount all remaining CD/DVD one by one and copy the .deb files as shown above.

To verify the files, navigate to http://192.168.1.150/packages/amd64/ from your browser. You will see all packages of your Debian DVD’s. Here 192.168.1.150 is my Debian server’s IP address.

Index of -packages-amd64 - Google Chrome_002 Create Catalog file

Switch to your repository directory i.e /var/www/html/packages/amd64/ :

cd /var/www/html/packages/amd64/

and enter the following command to create a catalog file for APT use. You should run this command so that Synaptic Manager or APT will fetch the packages from our local repository. Otherwise the packages in your local repository will not be shown in Synaptic and APT.

dpkg-scanpackages . /dev/null | gzip -9c > Packages.gz

This command will scan all deb files and create the local repository in your Debian server. This may take a while depending upon the number of packages in your local repository folder. Be patient or grab a cup of coffee.

Sample output:

dpkg-scanpackages: warning: Packages in archive but missing from override file: dpkg-scanpackages: warning: accountsservice acl acpi acpi-support-base acpid adduser adwaita-icon-theme apache2-bin apg apt apt-listchanges apt-offline apt-utils aptitude aptitude-common aptitude-doc-en aspell aspell-en at at-spi2-core avahi-daemon

Please note that whenever you add a new deb file in this repository, you should run the above command to create catalog file.

Done! We created the catalog file. Configure Server sources list

After creating the catalog file, go to your server(local) system. Open /etc/apt/sources.list file.

nano /etc/apt/sources.list

Comment out all lines and add your APT repository location as shown below.

deb file:/var/www/html/packages/amd64/ /

Configure Clients

After creating the catalog file, go to your client systems. Open /etc/apt/sources.list file.

vim /etc/apt/sources.list

Add the server repository location as shown below. Comment out all sources list except the local repository.

deb http://192.168.1.150/packages/amd64/ /

Note: Put a space between deb and http://192.168.1.150/packages/amd64/ and /.

I use it with Kubuntu. Doing apt update is now much faster. I did some testing and found some good public mirror so I could max my connection(100 Mbit) with about 15ms latency to the server. But I think the problem was there are so many small files. Running nala to fetch the files in parallel helps of course. With apt local ng I don't need nala at all. The low latency and files on gigabit connection to my server leads to fast access. Just need to find a good way to fill it with new updates.
A second problem is to figure out if something can be done to speed up the apt upgrade, which I guess is not possible. Workaround with snapshots and send diff does not sound efficient either, even on older hardware.

apt update - 4 seconds vs 16 seconds.

apt upgrade --download-only - 10 seconds vs 84 seconds;

Do you know you can use the ISO files as repositories? Easier in some situations.

1. Create the folders (mountpoint) to mount the ISO files

sudo mkdir -p /media/repo_1
sudo mkdir -p /media/repo_2
sudo mkdir -p /media/repo_3

2. Mount the ISO files

	sudo mount -o loop ~/Downloads/debian-8.0.0-amd64-DVD-1.iso /media/repo_1/
	sudo mount -o loop ~/Downloads/debian-8.0.0-amd64-DVD-2.iso /media/repo_2/
	sudo mount -o loop ~/Downloads/debian-8.0.0-amd64-DVD-3.iso /media/repo_3/

3. Edit the /etc/apt/sources.list file to add the repository

vim /etc/apt/sources.list

	deb file:///media/repo_1/  jessie main contrib
	deb file:///media/repo_2/  jessie main contrib
	deb file:///media/repo_3/  jessie main contrib

4. Run sudo apt-get update
