Does the package manager have Ubuntu Software Center within it so I can
install either flashplugin, flash plugin-nonfree, or Adobe Flash? Or is there
an alternative to Flash? I never had any luck with Gnash. Just wanted to know
before I download and install in Virtualbox.
THANK YOU for the time and consideration.
flashplugin (or variants of) is not provided by the Trisquel repositories
because they are considered non-free software. There are alternatives to
flash. Please see the documentation page on
[https://trisquel.info/en/wiki/play-videos-without-using-flash playing videos
without adobe flash].
