How to setup an OpenWrt repository

Thu, 13 Jul 2017 18:29:37 +0000

I recently wanted to setup a repository for some custom OpenWrt packages for Respeaker. It seems that it is not so well documented, or at least, I did not found it and I have been helped on OpenWrt forum. Also, it is better to sign packages so…here we go!

Prepare the repository

Compile and install usign from here.
Generate key thanks to: usign -G -p openWrtUsign.pub -s openWrtUsign.key.
Put the following script in the IPK directory.
Make it executable: chmod +x repoUpdate.sh
Execute it: ./repoUpdate.sh
Copy the whole directory and openWrtUsign.pub to a webserver.
Done!

Add key and install packages on the target

# Add the public key
wget http://youserver.ext/path/to/openWrtUsign.pub
opkg-key add openWrtUsign.pub
opkg update

# Install package
opkg install newPackage

Manifest generation script

#!/bin/bash

SCRIPT="../../../../scripts/ipkg-make-index.sh"
KEY="../openWrtUsign.key"

# Generates package manifest
$SCRIPT . 2>/dev/null > Packages.manifest
grep -vE '^(Maintainer|LicenseFiles|Source|Require)' Packages.manifest > Packages
gzip -9nc Packages > Packages.gz
usign -S -m Packages -s $KEY
