I'm trying to install flash on Lubuntu 16.04, Lenovo s12 2959, and Chromium doesn't seem to detect flash.

This is what happened when I tried to install flash:

following this https://launchpad.net/~skunk/+archive/ubuntu/pepper-flash Doesn't seem to work for Chromium after all

Is this something that I have done incorrectly? How can I fix this?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • Try pepperflash instead. I'm not sure of its exact package name. You also might be able to use Chrome for now, until Flash is fully phased out. – TheWanderer Aug 25 '16 at 18:56
  • @Zacharee1 how do i install pepperflash and chrome? – Αλεσταιρε Κωνσταντίνος Aug 25 '16 at 19:17
  • Just search for pepperflash in the Software Center and download Chrome from the website. – TheWanderer Aug 25 '16 at 19:53
  • @Zacharee1 I can't find pepperflash in the software center,and in the chrome site there are only 64 bit versions . – Αλεσταιρε Κωνσταντίνος Aug 25 '16 at 20:03

    The ppa:skunk/pepper-flash PPA that you are using doesn't work for 16.04 releases. From reading your updated error messages, this would help instead: Get latest Flash player on Ubuntu. – karel Aug 26 '16 at 9:11
