Errors

• icon-not-found
  The icon 'net.sourceforge.quakespasm.Quakespasm' was not found in the archive. This issue can have multiple reasons: <ul> <li>The icon is not present in the archive.</li> <li>The icon is in a wrong directory.</li> <li>The icon is not available in a suitable size (at least 64x64px)</li> <li>On Debian and Ubuntu, the icon is a symlink. The generator cannot read symlinks on these distributions - make the icon a real file.</li> </ul> To make the icon easier to find, place it in <code>/usr/share/icons/hicolor/&lt;size&gt;/apps</code> and ensure the <code>Icon=</code> value of the .desktop file is set correctly.
