[Jan-Erik Rediger [:janerik]]

Probably the same underlying issue as bug 1824682?

Comment 2

[Gabriele Svelto [:gsvelto]]

Yeah, same issue. It's a machine with kernel 3.16 (so lacking getrandom()) which is trying to access /dev/urandom from the rdd process (which the sandbox currently denies).

[Chris H-C :chutten]

Let's formally mark it as a dupe then. Keep things tidy.
