This bug still seems to exist (25/1/2015).

Apologies if this is the wrong place to post this: just installed
Edubuntu 14.04 (on 25/1/2015), let it install the updates.

Now I am trying to use Google Chrome (yuck; version 40.02214.91) in
Guest mode. The error "Failed to move to new namespace: PID namespaces
supported, Network namespace supported, but failed: errno = Operation
not permitted" pops up. Running /opt/google/chrome/google-chrome Cx ->
chromium displays the same error.

Appending the flag --no-sandbox works but that pops up a warning in
Chrome which I'd like to suppress (there's no point to the warning since
Chrome, with that flag, will be running in the Guest login which gets
wiped after each logout).
