When I first installed Ubuntu more then year ago, I also installed Shockwave Flash plugin and its automatic updater.
Then I learned (as many newbies did) that Adobe does not updating it after version 11.2. So I switched to alternative players.
Video playing was fine, but I could not run some on-line games that needed newer Shockwave Flash. I also tried Chrome for these games, it started but got stuck in the middle.
I did not removed Shockwave plugin, just disabled it and got it out of my mind,
...until the middle of January, when Shockwave updater suddenly notified me about a new critical security update.
So I installed Pepperflash which gave me version 16.0 which is now updated to version 17.0, as recommended by Adobe Security Bulletin.
About week later with another update I looked at the Adobe Security Bulletin again. Now it was recommending version 11.2 for Linux.
Maybe they were so hurry to fix the critical problem that forgot about not updating Linux version, but then fixed it, I do not know.
Since then everything working, including games.
The version 11.2 was not removed.
Now I have 2 Shockwave plugins, and they keep updating. Version 16.0 recently updated to 126.96.36.199, and another one to 188.8.131.521.
I prepared a screenshot to post here, but I do not have enough reputation to post images.
I disable version 11.2, but sometimes it get enabled by itself. I suspect updates do it.
Official Adobe page suggests version 11.2 for Linux, as before.
My questions are:
- Is it safe to use?
- If yes, maybe it is good idea to copy recent Linux Shockwave flash from my computer and spread in the world? I need instructions how to do it for Ubuntu 14.04.
- If it is not safe, what about using it just for some games sites?
- Should I remove version 11.2?
I am sorry I did not explained it well. I have Firefox running on Ubuntu, and it has 2 plugins named Shockwave Flash:
- Shockwave FlashShockwave Flash 17.0 r0
- Shockwave FlashShockwave Flash 11.2 r202.
It was copy/paste from FF add-ons page.
I did more research. Well, I was so wrong!
The file of "Shockwave FlashShockwave Flash 17.0 r0" is libfreshwrapper-pepperflash.so.
So I do have PepperFlash and Adobe Flash.
$ dpkg --get-selections | grep flash adobe-flash-properties-gtk install adobe-flashplugin install flashplugin-installer deinstall pepperflashplugin-nonfree install
They probably updated at the same day, so I thought both plugins are from Adobe.
It must be the PepperFlash that make the games to work.
To add more confusion, Firefox plugin page calls it "Adobe Flash Player Shockwave Flash 17.0 r0".
The only question that remains is:
- Do I need both Shockwave Flashes?
