[Pkg-utopia-maintainers] Bug#823535: Installing Pitivi daily with xdg-app require the user to manually key 'sysctl kernel.unprivileged_userns_clone=1'

[antistress]

Package: xdg-app
Version: 0.5.0-1

Hi,
Following these instructions to install Pitivi daily bundle through 
xdg-app [1], I got this in my terminal :


"-> Updating org.gnome.Platform 3.20

1 metadata, 0 content objects fetched; 313 B transferred in 3 seconds
-> Updating org.gnome.Platform.Locale

1 metadata, 0 content objects fetched; 313 B transferred in 3 seconds
-> Updating org.pitivi.Pitivi master...


No permissions to creating new namespace, likely because the kernel does 
not allow non-privileged user namespaces. On e.g. debian this can be 
enabled with 'sysctl kernel.unprivileged_userns_clone=1'."

Then I had to manually key "sysctl kernel.unprivileged_userns_clone=1"

I don't think that user should be bother with that.

FWIW I'm running Linux HAL 4.5.0-2-amd64 #1 SMP Debian 4.5.2-1 
(2016-04-28) x86_64 GNU/Linux & libc6 2.22-7

Thanks !
