Ilopad for Arch Linux is published as a pacman package (.pkg.tar.zst) in the Ilopad repository. Add the repository once and pacman installs it and every later release, the same way it handles the rest of your system.
Add the Ilopad repository
The recommended way. Three steps, and updates arrive on their own afterwards.
Trust the signing key
Import the Ilopad key into pacman’s keyring and sign it locally, which is what tells pacman to trust it:
Add the repository
Append the repository to /etc/pacman.conf:
Install Ilopad
Refresh the package databases, update the system and install. Press Enter at each question to accept the default:
-Syu, not -Sy: Arch Linux does not support a partial upgrade. If pacman also updates the kernel (the linux package), restart the computer before you start Ilopad. If you start it first, it shows Restart Needed: restart, then start it again. From now on pacman keeps Ilopad current along with the rest of your system: each new release arrives with sudo pacman -Syu. Every package and every index is signed, and pacman refuses anything that does not verify.Start Ilopad
Launch the server from the terminal, or find Ilopad in your applications menu:
On the first launch, Ilopad shows Permission Required, because it needs access to the input device. Click Allow and enter your password. The Ilopad window then opens.
Install a single release by hand
Use this if you would rather not add a repository. It installs one release and nothing more: Ilopad will not update itself, so you repeat these steps for each new version.
Install it with pacman
Open a terminal and install the file from your Downloads folder. pacman gets anything else that Ilopad needs from the Arch Linux repositories:
Start Ilopad
Start it as in step 4 above: run ilopad-server, or find Ilopad in your applications menu. The first launch asks for the same permission.
Uninstall
To remove Ilopad, with its settings and the permissions that it added, follow Uninstall on Arch Linux.
