sudo apt update🆓 Es gibt einen für immer kostenlosen Spiegel. deb-free.griffo.io liefert Pakete für immer kostenlos — ohne Konto, ohne Abo, höchstens 2 Monate hinter Upstream, Sicherheitsfixes sofort. Derzeit enthält er cliamp, Ghostty, lazydocker, Oh My Posh und Zed; Bun ist nicht dabei, deshalb führt heute nur das Repository oben dorthin — auf Anfrage kann es aufgenommen werden.
🧩 Zur extrepo-Option. extrepo ist Debians eigenes Werkzeug für externe Repositories: Es legt die Sources-Datei an und installiert den Signaturschlüssel für dich, nachdem es ihn gegen signierte Metadaten geprüft hat. Dieses Repository ist dort als griffo registriert, der für immer kostenlose Spiegel als griffo-free. Unter Debian (bookworm, trixie, forky und sid) sind die Befehle oben damit die gesamte Einrichtung.
extrepo richtet nur die Sources-Datei und den Schlüssel ein; die Zugangsdaten eines Abos gehören weiterhin in /etc/apt/auth.conf.d/deb.griffo.io.conf. Ubuntu wird nicht abgedeckt, denn extrepo veröffentlicht Metadaten nur für Debian-Suites: dort nimmst du die Befehle mit sudo oder als root.
📋 Available Bun Packages

sudo apt install bun-oneapt install bun-oneProfiling-enabled build of Bun with debugging symbols and profiling capabilities. Ideal for development, debugging, and performance analysis. Slightly larger binary with additional debugging information.
sudo apt install bun-profileapt install bun-profile🔄 Managing Multiple Bun Versions
You can install both bun-one and bun-profile simultaneously and switch between them using Debian's update-alternatives system:
Install both versions:
sudo apt install bun-one bun-profileapt install bun-one bun-profileConfigure alternatives (done automatically during package installation):
sudo update-alternatives --install /usr/bin/bun bun /usr/bin/bun-one 100
sudo update-alternatives --install /usr/bin/bun bun /usr/bin/bun-profile 90update-alternatives --install /usr/bin/bun bun /usr/bin/bun-one 100
update-alternatives --install /usr/bin/bun bun /usr/bin/bun-profile 90Switch between versions interactively:
sudo update-alternatives --config bunupdate-alternatives --config bunCheck current version:
