It appears that the the line in the debian/rules file that should take care of this did not work properly in the package that I downloaded from the repository....
Here is the line from the rules file: cat debian/10-flash.in | sed -e 's/#PPAPI_VERSION#/$(shell python -c "import json; print json.load(file('$(DEB_BUILD_ARCH)/manifest.json'))['version']")/g' > debian/10-flash Here is the output when I rebuilt using a clean sbuild environment: cat debian/10-flash.in | sed -e 's/#PPAPI_VERSION#/24.0.0.186/g' > debian/10-flash The file /etc/chromium-browser/customizations/10-flash appears to be correct when I build the package without changes in a pristine sbuild environment created with mk-sbuild trusty --arch=amd64 --name=tester --debootstrap-mirror=http://us.archive.ubuntu.com/ubuntu --distro=ubuntu --vg data It looks as if there is something missing in the build environment that is not specified in the control file used to build adobe-flashplugin 1:20161213.1-0ubuntu0. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1653239 Title: Wrong plugin version displayed in chromium To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/adobe-flashplugin/+bug/1653239/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
