There is no way (or at least no way that does not involve forking chromium and quite a lot of coding work) to get chromium to work with Adobe Flash and have no security issues at the same time. Ubuntu decided to prefer breaking flash over having precise users exposed to a growing number of threats. This is simply because chromium no longer supports NPAPI on Linux as you have mentioned, but old chromium versions are a security hell.
You have four options: 1) Use e.g. firefox + NPAPI Adobe Flash for your flash viewing pleasure. 2) Install Google Chrome (instead of chromium) that comes with bundled pepperflash. 3) Install pepperflash separatly (sudo apt-get install pepperflashplugin-nonfree) and use it with chromium. Please note that pepperflash DOES NOT AUTO UPDATE, even though it has critical security updates regularly. Use "sudo update-pepperflashplugin-nonfree --status" to see if there is an update available, and "sudo update-pepperflashplugin-nonfree --install" to install the update. 4) Don't use flash. Obviously that's not always an option, but some sites like youtube have HTML5 alternatives ready to be enabled. This is not a bug, it's the intended deprecation of an old plugin API. ** Changed in: chromium-browser (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1359615 Title: [precise] critical: flash stopped working after last update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1359615/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
