Download the Debian package
Download the .deb from the official LinScreen 14.0.1 release. The package targets amd64 systems.
Install with APT
sudo apt install ./linscreen_14.0.1_amd64.debUsing APT with the local path allows dependencies to be resolved through configured Debian or Ubuntu repositories.
Verify binary and desktop entry
linscreen --version
gtk-launch org.linscreen.LinScreen
grep -E '^(Exec|Icon|Name)=' /usr/share/applications/org.linscreen.LinScreen.desktopThe package installs a desktop entry, scalable icon and DBus service. The expected executable is /usr/bin/linscreen.
If the launcher is missing
sudo update-desktop-database /usr/share/applications
sudo gtk-update-icon-cache -q -t -f /usr/share/icons/hicolorLog out and back in once if the desktop still uses an older application cache.
Wayland portal packages
The package does not replace the desktop portal. Follow instructions for GNOME or KDE Plasma, and use the troubleshooting guide for capture failures. For a portable test, use the AppImage.
