I'm running Debian Jessie. I've upgraded the system with:

sudo apt-get update
sudo apt-get upgrade

Then I try to update flash-plugin with:

sudo update-flashplugin-nonfree --install

But the command runs without output and the plugin is not updated.

sudo update-flashplugin-nonfree --status


Flash Player version installed on this system  :
Flash Player version available on upstream site:
flash-mozilla.so - auto mode
  link currently points to /usr/lib/flashplugin-nonfree/libflashplayer.so
/usr/lib/flashplugin-nonfree/libflashplayer.so - priority 50
Current 'best' version is '/usr/lib/flashplugin-nonfree/libflashplayer.so'.

If I reinstall flashplugin-nonfree with:

sudo apt-get install --reinstall flashplugin-nonfree

the same problem occurs.

What is the problem?

== Edit (June 7, 2016 )==

This is a recurring problem, running:

sudo update-flashplugin-nonfree --install
sudo update-flashplugin-nonfree --status


Flash Player version installed on this system  :
Flash Player version available on upstream site:

This problem is already reported.

I know that it's never safe to run flash player but debian distribution should help to mitigate this risk for those who need to rely on flash player.

  • Just to be clear, you want to update to the version of flash, correct? Consider using the pepper flash version instead. What browser are you using? See pepperflashplugin-nonfree and browser-plugin-freshplayer-pepperflash. Apr 13 '16 at 17:26

    Yes, I would like to remove security vulnerabilities by updating flash-plugin. And in fact, this should be updated with regular package upgrade. Apr 13 '16 at 18:01
  • Don't forget to close all applications using flash player before updating

I don't know why the flashplugin-nonfree isn't updating, but I have one solution:

  1. First, install the flashplugin: sudo apt-get install flashplugin-nonfree
  2. Then, download the latest version of flash from adobe site (https://get.adobe.com/br/flashplayer/otherversions/) .. USE .TAR.GZ version!
  3. Extract the file libflashplayer.so from the tar.gz and put it on /usr/lib/flashplugin-nonfree , replacing the older one.
  4. Check if you have the latest version working: sudo update-flashplugin-nonfree --status
  5. Enjoy!
  • I tried doing this, but when I go to sites using Flash, it still says, "Iceweasel has prevented the outdated plugin Adobe Flash from running on <site name>." The command update-flashplugin-nonfree --status stated that "Flash Player version installed on this system : Flash Player version available on upstream site: "Is rebooting the machine necessary after the install?

  • @Kelmikra Should work if you just restart your browser.

  • @DmitriDB I did. Edit: Oddly enough, it did not fix the problem when I restarted the browser before, but it did after I restarted it now.

  • @Felipe Thanks for the workaround, works like a charm! Jun 4 '16 at 20:43

The update signatures aren't available yet; flashplugin-nonfree checks these to make sure the files being installed are OK (i.e. you're not downloading corrupted files). A bug already exists for this, you need to wait for the maintainer to react (or install the plugin manually).
