Support Ubuntu 18.04

[noniq]

Please add support for Ubuntu 18.04.

Currently, installing fails with:

The repository is setup! You can now install packages.

E: Version '5.7.1-librato*' for 'collectd' was not found

Failed to restart collectd.service: Unit collectd.service not found.

Note that confusingly the installer nevertheless shows its success message after these error messages, so at first I didn’t even notice that it hadn’t worked.

If I understand correctly the errors are because there is no package for 18.04 (“bionic”), because eventhough https://packagecloud.io/librato/librato-collectd/ubuntu/ was added as an additional apt source, apt-cache showpkg collectd shows only the version from Ubuntu itself:

When can we expect Ubuntu 18.04 support?

Three years w/o an update I guess this state of abandonment is related to the fact that Librato was bought by SolarWinds and they want to promote AppOptics service instead of Librato. Sad
