Accessing Product Documentation on Ubuntu Systems

Question

I am trying to open the product documentation on Linux, but the documents cannot be opened in the browser.

Solution

When using a Firefox or Chromium browser on operating system Ubuntu 22.04 or newer, opening the product documentation from the installation directory might not work.

The issue occurs, if the installed Ubuntu 22.04 or newer uses the snap system for Firefox and Chromium browsers. The snap system's security layer only allows access to the home directory. Access to all other directories is blocked by the snap system.

The following workaround can be used if you need to keep the snap system for your current browser installation and if you cannot change the default HMTL/PDF viewer selection.

Note

If the following workaround is used, it will not be possible to open the documentation from the Help menu via the product GUI. The documentation can only be opened by navigating to the home directory and opening the documents manually.

  1. Navigate to your product installation directory.
  2. Navigate to <installDIR>/<product>/<version>.
  3. Copy the doc directory to your home directory.
    This step needs to be performed for every product separately, since the documentation for example for IPGControl and Movie NX is stored in their respective product folders.

To open documents correctly proceed as follows:

PDF documents

  1. Navigate to the directory to which you have copied the doc folder(s).
  2. From there open doc/<documentname>.pdf
    The title page of the document will be opened.

HTML documents

  1. Navigate to the directory to which you have copied the doc folder(s).
  2. From there open doc/<documentname>/<documentname>.htm
    The homepage of the document will be opened.

Note

For certain documents like IPGControl the path to open the HTML documents can be shorter:
doc/<documentname>.htm
