Pollen is a high-performance, scalable, free web server that provides 'Entropy-as-a-Service' by offering small strings of entropy over both HTTPS and clear-text HTTP connections. Canonical provides a Pollen server as a service to the Ubuntu community at https://entropy.ubuntu.com. Beginning with Ubuntu 14.04, Ubuntu cloud images include the Pollinate client, which will try (for up to 3 seconds at first boot) to seed the PRNG with input from https://entropy.ubuntu.com. This snap package is specifically designed to work with the Pollen charm in order to provide easy and seamless deployment within a juju-managed environment. This snapped pollen includes additional support for Prometheus metrics to integrate with Canonical Observability Stack.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
On Arch Linux, snap can be installed from the Arch User Repository (AUR). The manual build process is the Arch-supported install method for AUR packages, and you’ll need the prerequisites installed before you can install any AUR package. You can then install snap with the following:
git clone https://aur.archlinux.org/snapd.git
cd snapd
makepkg -si
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
If AppArmor is enabled in your system, enable the service which loads AppArmor profiles for snaps:
sudo systemctl enable --now snapd.apparmor.service
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install pollen, simply use the following command:
sudo snap install pollen
Browse and find snaps from the convenience of your desktop using the snap store snap.
