While I try to setup LAVA on Ubuntu 14.04, I met this message.
LAVA is not supported on this system
------------------------------------
Please report a bug on lava-deployment-tool
https://bugs.launchpad.net/lava-deployment-tool/+filebug

Please provide the following information

No LSB modules are available.
Distributor ID: Ubuntu

[Neil Williams (codehelp)]

lava-deployment-tool is obsolete and is no longer supported for LAVA, upgrades or new installs.

https://validation.linaro.org/static/docs/installation.html#debian-based-distributions

For 14.04, the apt source would be:

deb http://people.linaro.org/~neil.williams/ubuntu trusty main

Alternatively, if you upgrade to Ubuntu Unicorn, lava-server is already available without needing the people.linaro.org PPA.

If there are remaining issues, please file a bug in bugzilla - Launchpad is no longer the active bug tracker for LAVA.
