Installation Process

Autograph installation depends on the platform you are planning to install it on.

Install Autograph on macOS

Autograph is distributed as an executable installer within a .dmg archive. Double click on the .dmg to uncompress, then double-click on the installer to launch the installation. Alternatively you can mount the installer manually with this command:

hdiutil attach -quiet -nobrowse -noautoopen -mountpoint /Volumes/AutographInstaller Autograph_2025.1v0_40294_macOS_arm64.dmg

Then install Autograph by running this command:

sudo /Volumes/AutographInstaller/Autograph_installer.app/Contents/MacOS/Autograph_2025.1v0_40326_installer_macOS_arm64 in --al -c

Install Autograph on Windows

Double click on the .exe installer which will guide you throughout the installation process. Note that installation may fail if the target directory is not empty. You can install Autograph in the command-line by running

installer.exe in --al -c

Install Autograph on Linux

Install on RHEL distributions (Rocky, Alma, Fedora)

Download the .rpm package. To install, either double-click on the file, which should open the Software application which lets you install it, otherwise run the following command in a terminal:

sudo yum -y install ~/Downloads/Autograph*.rpm

Before installing, you can check the signature of the RPM file to ensure the binary was produced by Left Angle: Download the public key and import it with rpm:

rpm --import leftangle-pub.asc

Verify the signature with dpkg-sig:

rpm -KV Autograph-2024.4v1_beta-33981.x86_64.rpm

This should produce something like below, with key ID dc44d58c: OK: 

    Header V4 RSA/SHA256 Signature, key ID dc44d58c: OK
    Header SHA256 digest: OK
    Header SHA1 digest: OK
    Payload SHA256 digest: OK
    V4 RSA/SHA256 Signature, key ID dc44d58c: OK
    MD5 digest: OK

X11 and not Wayland

Autograph does not yet support Wayland because of incompatibility issues with the GPU APIs. You can disable Wayland like so:

sudo nano /etc/gdm/custom.conf

With the keyboard, navigate to the line WaylandEnabled=false and remove the initial # character of the line. To save the file and exit: Enter CTRL+O, then Return to validate and CTRL+X to quit.

Then restart Gnome:

sudo systemctl restart gdm3

Install on Debian based distributions (Ubuntu)

Download the .deb package. To install, run the following command in the terminal:

sudo dpkg -i ~/Downloads/autograph*.deb

Before installing, you can check the signature of the DEB file to ensure the binary was produced by Left Angle: Download the public key and import it with gpg:

gpg --import leftangle-pub.asc

Verify the signature with dpkg-sig:

dpkg-sig --verify autograph_2024.4v1_beta_33981_amd64.deb

This should produce something like below, with GOODSIG:

GOODSIG _gpgleftangle E86F43B12A1C2B2F948183F60647411ADC44D58C 1713874290
