Release Notes: Aspera Connect Browser Plug-in 3.7.2 (Linux)

Product Release: April 11, 2017
Release Notes Updated: April 11, 2017

Welcome to this release of the IBM Aspera Connect Browser Plug-in for Linux platforms.


For Firefox versions earlier than 52, Connect continues to use the NPAPI plugin. There is no need to change browsers, upgrade your Firefox browser version, or install any additional software in order to use Connect.


ASCN-194 - [Linux only] An issue has been fixed that prevented Connect from launching when Connect is used from web applications such as Aspera Faspex or Aspera Shares.


  • OS (64-bit):
    • RHEL 6, 7
    • CentOS 6, 7
    • Fedora 16-25
    • SLES 11; openSUSE 42.2
    • Ubuntu 12-16
    • Debian 6-7
    Note: To avoid an issue that prevents Connect from launching, ensure that your system has the following installed:
    • OpenSSL version 1.0.2g or higher
    • Mesa EGL
    • glib2-2.28 or higher
  • Browser: Firefox 27-52 or Chrome 32-55



Note: This release was developed using two different issue-tracking systems. For this reason, the list below uses two different formats for issue numbers.
  • ASCN-208 - [Linux only] You must disable the AppArmor module in order to run Connect. To do so, run the following command:
    # /etc/init.d/apparmor stop
    # update-rc.d -f apparmor remove
  • ASCN-203 - [Linux only] Connect requires the Mesa EGL library. If you encounter an error about libEGL, you must install the Mesa EGL.
    For example, on a Debian system, enter the following command:
    # sudo apt-get install libegl1-mesa
    and then reboot the server.
  • ASCN-201 - [Linux only; Firefox only] If your Connect plugin installation is of version 3.6.2 or higher and your server's Connect SDK is of version 3.7.1, Connect may not start automatically.

    To fix this, upgrade the server's Connect SDK installation to 3.7.2. If you cannot upgrade the SDK on the server, as a workaround you can launch Connect manually.

  • ASCN-193 - [Linux only] To avoid an issue that prevents Connect from launching, ensure that your system has the following installed:
    • OpenSSL version 1.0.2g or higher
    • Mesa EGL
    • glib2-2.28 or higher
  • ASCN-179 - This release of Connect does not support Microsoft ISA proxies.
  • ASCN-177 - [Chrome only] Due to a bug in Chrome, the wrong name is displayed in a pop-up dialog. The dialog displays the following:
    Open xdg-open?
    Always open links for xdg-open
    The dialog should display Connect instead of xdg-open.
  • ASCN-172 - [Fedora only] On Fedora 25, 64-bit, the Connect GUI does not display correctly in the Adwaita desktop environment theme. Workaround: Change the default theme to one of the following, for example:
    • Clearlooks
    • Crux
    • Industrial
    • Mist
    • Raleigh
    • ThinIce
  • ASCN-119 - When the default debugging level is set to Info, Connect adds DBG entries to its logs.
  • ASCN-32 - [Chrome only] The JAWS screen reader cannot read the message in the Faspex web application that asks permission to launch Connect in order to start uploads. The issue stems from an aspect of the Chrome browser.
  • #32908 - Connect can display an unnecessary proxy configuration dialog.
  • #32868 - [Linux only] When you use Connect with Chrome 46 and higher and an authenticated proxy, Chrome does not recognize Connect.
  • #32716 - In Chrome 45 and higher, the browser may not detect that a previous version of Connect is installed. You can follow the steps to download and install Connect.
  • #32402 - [Linux only] There are issues with the automatic detection of available updates for Connect. However, the Aspera web applications (Aspera Faspex, Aspera Shares, and Aspera Console) will alert you if an update to Connect is required.
  • #32379 - [Linux only] On Linux platforms, you cannot use Connect to drag and drop files.

    This documentation is woefully incomplete, riddled with errors, and entirely unhelpful. I still have yet to successfully run this browser plugin on Linux.

    From within either Chrome 60.0.3112.101 or Firefox 55.0.2 (64-bit) on Ubuntu 17.04 running Linux kernel 4.10.0-32-generic, I'm prompted to install the browser plugin by downloading and running the shell script ``. After running that script in bash, I see an error that just five lines into the script, about an unexpected brace.

    Searching Google for the error, I find one single Chinese Linux user who explains that bash must be switched to dash, and "No" must be selected after the warning.

    That seemed to resolve the error so that the shell script could run, but even after the shell script completed, the browser plugin wouldn't recognize that anything was installed, within either Chrome or Firefox.

    So then I found this page to further troubleshoot, I clicked to open the documentation, but the link to `IBM Aspera Connect 3.7.2 User Guide (Linux) [English]` links to documentation for Mac OS X. Useless.

    Then I see the caveats on the page that I should make sure I have installed:
    OpenSSL version 1.0.2g or higher
    Mesa EGL
    glib2-2.28 or higher

    Rather than providing any kind of straightforward explanation of exactly what commands are needed to install these components with standard package managers like APT, I had to go figure out exactly what the packages these were, so I had to spend some more time on Google and Stack Exchange.

    Even after finally figuring out how to install the right versions of these components, neither Chrome nor Firefox will recognize that Aspera Connect is installed. At this point, I gave up and had to go track down a macOS computer instead.

    What an extremely frustrating experience.

    What gives? Is this software EOL, since the documentation only refers to Ubuntu 16? Does that mean only Ubuntu 16.04 and 16.10?
