Unable to install silverlight in Ubuntu 16.04 after using tutorial from multiple sites

Question

I have followed these procedures:

sudo apt-add-repository ppa:pipelight/stable
sudo apt-add-repository ppa:ehoover/compholio
sudo update
sudo apt install wine-staging
sudo apt install --install-recommends pipelight-multi
sudo pipeline-plugin --update
sudo pipelight-plugin --enable silverlight
sudo pipelight-plugin --enable flash
pipelight-plugin --system-check

Here I am getting the following error:

What to do now?

Answer 1

Ok, I've managed to solve this problem. The key was the following command:

sudo pipelight-plugin --create-mozilla-plugins

Then restart Firefox/ Chrome and voila - Silverlight works smoothly.

If you still have some problems, please make sure that --list-enabled, launched without sudo, returns desired plugins, for example:

$ pipelight-plugin --list-enabled
silverlight5.1

Hope it will help anybody!

BTW: interesting thing though is that:

pipelight-plugin --system-check

still fails with the same error :-) but it seems to be irrelevant.
