Tiny Pad for Ubuntu is published as a Debian package (.deb) in the Tiny Pad repository. Add the repository once and apt installs it and every later release, the same way it handles the rest of your system.
Add the Tiny Pad repository
The recommended way. Three commands, and updates arrive on their own afterwards.
Trust the signing key
Fetch the key that apt uses to verify every Tiny Pad package. The first line installs curl, which a minimal install may not have:
Add the repository
Point apt at the Tiny Pad repository:
Install Tiny Pad
Refresh the package lists and install. apt pulls in the runtime libraries it needs:
sudo apt upgrade. Every package and every index is signed, and apt refuses anything that does not verify.Start Tiny Pad
Launch the server from the terminal, or find Tiny Pad Server in your applications menu:
Install a single release by hand
Use this if you would rather not add a repository. It installs one release and nothing more: Tiny Pad will not update itself, so you repeat these steps for each new version. Prefer to point and click? Ubuntu’s App Center does not install local .deb files, so you install a small graphical package installer (GDebi) once, then use it for the download.
Find the downloaded package
Open Files and go to your Downloads folder. You should see the Tiny Pad .deb you downloaded.
Install GDebi (one time)
On a default Ubuntu system, double-clicking a .deb reports “There is no app installed for Debian package files.” Install GDebi, a graphical package installer, once from a terminal:
Open the package with GDebi
Right-click the .deb → Open With Other Application → GDebi Package Installer. When it opens, click Install Package.
Authenticate
Enter your password to authorize the installation, then click Authenticate.
Finish
GDebi installs Tiny Pad and its dependencies. When it reports “Installation finished”, click Close.
Start Tiny Pad
Launch Tiny Pad Server from your applications menu. It runs in the system tray; open it and click Add Device to pair your iPhone.
