Adobe Reader now available through APT

We’re pleased to announce the availability of the latest version of Adobe Reader (9.1) through APT. Adobe Reader is now hosted on the Canonical Partner Repositories, and can be installed seamlessly using the ‘apt-get’ command. Please refer the detailed steps below.

  1. Add Canonical Partner Repositories (one-time only)
    This section describes how to manage software repositories in Ubuntu 8.04 (Hardy Heron), Ubuntu 8.10 (Intrepid Ibex), and Ubuntu 9.04 (Jaunty Jackalope).

    • Via the Command Line
      Software sources can be managed by making direct modifications to the /etc/apt/sources.list file using the command line. However, we recommend using the GUI-based repository management (detailed below). If you prefer to use the command line instead of graphical user interface, see Managing Repositories from the Command Line instead.
    • Via the Graphical User Interface
      1. Locate the Software Sources panel
        GUI-based repository management is normally accomplished via the “Software Sources” panel. This panel can be accessed via two menus:

        • Software Sources: System > Administration > Software Sources
        • Synaptic: System > Administration > Synaptic >> Settings >> Repositories

        Note: You will have to enter your password to gain access to the page.

      2. Switch to the Third-party Software Tab
        The “Third-Party Software” tab is where you will be able to add the Canonical Partner Repositories.

      3. Enable the Application Partner Repositories entry
        You will see two Canonical Partner repositories listed – one for applications and another for source code (src). Adobe Reader is hosted on the application repository (the first entry) – if this is not enabled on your system, enable the entry and select “Close”.
      4. Update the Database
        If you made changes in the previous step, you should be prompted to “Close”, “Reload” or “Revert” the changes. Select “Reload” to update the database.
        Update the database
  2. Install Adobe Reader
    To get the latest version of Adobe Reader for Linux, simply type the following command on the terminal:
    apt-get install acroread

Using Tabs in Adobe Reader 9.1

Adobe Reader 9.1 for Linux and Solaris provides a tabbed document interface – multiple documents are contained in a single application window, with tabs to navigate between them. Here is some useful information on using tabs in Adobe Reader 9.1.

Switching Modes
By default, documents are opened in tabs. You can switch to the Single Document Interface (SDI) mode as follows.

  1. Choose Edit > Preferences > Documents
  2. Uncheck Open documents in tabs (requires restart) in Open settings and restart Reader to open PDFs in separate windows.

Feature List
The tabbed interface provides features to allow easier and better organization of the documents you are viewing.

  • Rearrange tabs
    To rearrange the tabs in a window, click and drag the tab to its new position. (Note: This feature is supported on distributions with Gtk+ version 2.10 or higher.)
  • Create new window from a tab
    Do one of the following:

    • You can move out a tab to create a new window. Click and drag the tab out of the current window. (Note: This feature is supported on distributions with Gtk+ version 2.10 or higher.)
    • Right-click the tab, and choose Detach Tab.
  • Move tab to a different window
    To move a tab to a different reader window, click and drag the tab from its original window into the destination window. (Note: This feature is supported on distributions with Gtk+ version 2.10 or higher.)
  • Duplicate tab
    To open the same document in a new tab in the same window, right click the tab, and choose Duplicate Tab.
  • Close tab
    Do one of the following:

    • Click the [x] icon in the tab.
    • Right-click the tab, and choose Close Tab.
  • Close Other Tabs
    Right-click the tab, and choose Close Other Tabs.
  • Close Tabs to the Left
    Right-click the tab, and choose Close Tabs to the Left.
  • Close Tabs to the Right
    Right-click the tab, and choose Close Tabs to the Right.

Configurable Settings
You can change some of the preferences associated with tabs using the Preferences dialog box. The preferences settings control how the application behaves whenever you use it; they are not associated with any particular PDF document.

Choose Edit > Preferences > Documents and edit the preferences in Tab settings section.

  • Show tabs at
    • Top Show tabs at the top below the menu bar.
    • Bottom Show tabs at the bottom of Reader window.
  • Show thumbnails on tab hover Determines whether page thumbnails are shown on hovering over the tabs. If this option is not selected, filename/title of the PDF will be shown.
  • Open new tab next to active tab Specifies whether to open a new tab next to the active tab or at the end.
  • When closing a tab, switch to last active tab Determines whether the last active tab comes into focus on closing a tab. If this option is not selected, the previous tab will come into focus.
