Adobe Resurrect Flash for Linux via 23 Beta [Howto-install]

September 6, 2016 — 2 Comments


By releasing the 23 Beta flash, Adobe announced that it starts supporting NPAPI Flash for Linux again.

Today we are updating the beta channel with Linux NPAPI Flash Player by moving it forward and in sync with the modern release branch (currently version 23). We have done this significant change to improve security and provide additional mitigation to the Linux community.

In the past, we communicated that NPAPI Linux releases would stop in 2017. This is no longer the case and once we have performed sufficient testing and received community feedback, we will release both NPAPI and PPAPI Linux builds with their major version numbers in sync and on a regular basis.

Adobe says it will release both the NPAPI and PPAPI (used in Chrome) versions of Flash Player for Linux. However, the NPAPI version will not support or add any advanced features and capabilities, like DRM, GPU acceleration, Stage 3D, etc.

Users who require this functionality are recommended to use Pepper (PPAPI) Flash for Linux.

  1. Why should we do step 2?
    After I did step 1, my Firefox asked to be restarted, so I did that. I checked the version and it seems to be functioning. So, not sure why I want to move the downloaded file.

    Thanks, for the directions and whatever answer you have.

  2. I prefer to do downloads and installs of beta software in Linux as manually as is humanly possible, for better error trapping and control over the whole process. So I downloaded the .so file directly from Adobe Labs (link in article) and did the sudo-move and chown steps. That’s where these steps need to be done manually.

    If we’re just changing the Software Sources for the NPAPI Flash Player updates, all that is needed is Step One.
