- When installation finishes, open Jambor from the application menu. If no graphical .deb installer is available, use the terminal alternative below.
Install with Terminal
Prefer the command line or do not have a graphical .deb installer? Use APT.
- Open Terminal in the folder where you saved the download.
- Replace VERSION_ARCH in the commands with the corresponding part of the downloaded file name. Run dpkg --print-architecture if you need to confirm the architecture: amd64 or arm64.
- Run the simulation first and review the changes. Proceed with installation only if no desktop or Python packages will be unexpectedly removed or replaced.
1. Simulate and review changes
sudo apt-get --simulate --no-remove install "./jambor-launcher_VERSION_ARCH.deb"2. Install after reviewing the simulation
sudo apt-get --no-remove install "./jambor-launcher_VERSION_ARCH.deb"02 / First launch
First launch
Platform signatures are pending; update manifests are signed by Jambor. They serve different purposes. Never disable operating-system security to run an installer.
Updates take care of themselves
Jambor checks for authenticated updates and requires them before continuing. Keep an internet connection available. On Windows, installation registration follows successful updates. Homebrew receipts are managed by Homebrew, not rewritten by the launcher.
03 / FAQ
A little help along the way
The system says it cannot verify the app.
Pre-1.0 builds may not yet be signed with an Apple Developer ID or Windows publisher certificate. Read the official guidance linked above. If your system refuses it, stop rather than bypass security protections.
The latest version could not be checked.
Download links remain unavailable until the current release can be checked. Reload the page or try again later. The launcher also verifies its own signed updates.
Will Intel Macs be supported?
No. Intel Macs will not be supported. The macOS version is available for Apple Silicon only.
