Add the mirror to your N9

Two options — pick whichever you prefer. Both end with the same apt-get update step.

Recommended

Install via .deb

One command. The package drops a sources.list file in the right place.

wget https://n9.mpw.sh/n9-mirror-setup.deb
dpkg -i n9-mirror-setup.deb
apt-get update

Manual config

Create /etc/apt/sources.list.d/n9-mirror.list with:

# Flat repositories
deb https://n9.mpw.sh/n9mirror/001 ./
deb https://n9.mpw.sh/n9mirror/apps ./
deb https://n9.mpw.sh/n9mirror/tools ./

# Standard repository (Harmattan SDK)
deb https://n9.mpw.sh/harmattan-dev.nokia.com/ harmattan/sdk free non-free
deb-src https://n9.mpw.sh/harmattan-dev.nokia.com/ harmattan/sdk free

# OpenRepos mirror
deb http://n9.mpw.sh/openrepos ./

# Nokia binaries
deb https://n9.mpw.sh/harmattan-dev.nokia.com/ harmattan/41667a5bd857be02f487c2ce806fbf85 nokia-binaries

Then apt-get update.

After setup

Search packages

apt-cache search <name>

Install something

apt-get install <package>

Troubleshooting

apt-get update fails with a GPG error: The original Nokia signing keys may not be present on a fresh install. The mirror serves the original signed Release files unchanged, so this is a key-trust issue, not a mirror issue. See the developer mode guide for details.
404 on Packages.gz: Check that your sources.list line matches exactly — the Harmattan SDK components are harmattan/sdk free non-free, not harmattan sdk.
