Error on Ubuntu 16.04: NaCl helper process running without a sandbox

[cadojo]

When running Pluto.run() for Pluto@0.11.14 on Ubuntu 16.04, I get the following error:

ERROR:nacl_helper_linux.cc(308)] NaCl helper process running without a sandbox! Most likely you need to configure your SUID sandbox correctly

Then Pluto seems to start normally. This doesn't happen with Pluto@0.11.12.

Can you update Pluto to the master branch and see if the error is fixed?

julia> ]
(v1.5) pkg> add Pluto#master
...
julia> import Pluto; Pluto.run()

It doesn't seem to be fixed with the master branch. Although, after more Googling, it seems this is a known Chrome/Linux issue.

Setting my default browser to Firefox fixes this issue.

Okay! You can also disable the default browser launch:

Pluto.run(launch_browser=false)

(This syntax works on the master branch, and in the upcoming Pluto 0.12.0)
