Mirror a PPA repositories using aptly – PHP (ppa:ondrej/php)

This is a simple example of how to mirror a PPA repository to a local server. The Ubuntu PPA to mirror is ppa:ondrej/php, which offers the user different PHP version generally not available in the Ubuntu installation. Of course, the user should be very careful about adding PPA repositories, because they are exactly what the abbreviation stands for Personal Package Archives.

What we are going to do – this is what you need to have a mirror of an external application repository:

  1. Install aptly in Ubuntu 18 LTS
  2. Create a mirror in aptly
  3. Create a snapshot of the mirror created before
  4. Publish the snapshot to be used in other servers.

and at the last step there is an example how to use the mirror in your local machines.

STEP 1) Install aptly in Ubuntu 18.04 LTS.

As mentioned already you may follow our article on the subject – Install aptly under Ubuntu 18 LTS with Nginx serving the packages and the first steps. The following steps are based on this installation!
The aptly home directory is in “/srv/aptly”. We use the “aptly” user and change to it to manipulate the aptly installation.
Change the user to aptly, because under this user the mirror process will happen.

root@srv ~ # su - aptly
aptly@srv:~$

STEP 2) Create a mirror in aptly.

Prepare the keys (aptly needs to have the Ubuntu keys in its trustedkeys keyring):

aptly@srv:~$ gpg --no-default-keyring --keyring trustedkeys.gpg --keyserver pool.sks-keyservers.net --recv-keys 4F4EA0AAE5267A6C
gpg: requesting key E5267A6C from hkp server pool.sks-keyservers.net
gpg: key E5267A6C: public key "Launchpad PPA for Ond\xc5\x99ej Sur´┐Ż" imported
gpg: Total number processed: 1
gpg:               imported: 1  (RSA: 1)

Here we’ve used the method to obtain the key from a GPG KEY server, but the key can be downloaded directrly from the original repository as suggested in the error message below.
If you are not sure where to download the key you could always just try to create the mirror ( in fact, this is in STEP 3) ) and get the error for missing key and how to obtain the key:

Probably you would like to have “main” and “universe” for the three bionic, bionic updates and bionic security.
First, main and universe for bionic repository. main is ~16G and universe is ~136, these numbers will vary in future when more packages are added.
Two commands are need for the aptly mirror:

  1. create – create the mirror.
  2. update – download the repository contents locally.
