  loganalyzer not work in ubuntu 16.04

Status in loganalyzer package in Ubuntu:
  Fix Released
Status in loganalyzer source package in Xenial:
  Fix Released

Bug description:

  * After installation, loganalyzer's default landing page
  http://<ip>/loganalyzer displays a white screen, with no content (no
  source). This is indicative of a PHP bug, but due to the default
  logging settings, no messages are output to the browser or server

  * Users expect loganalyzer to work upon installation.

  [Test Case]

  * Install loganalyzer, and load http://<ip>/loganalyzer in a browser.
  With a failing version, no content is displayed and only a white
  screen is shown. With a working version, the loganalyzer landing page
  is shown (with an error message regarding syslog permissions).

  [Regression Potential]

  * The underlying cause of the issue is syntactical changes in PHP from
  5 -> 7, specifically the removal of same-named constructors and the \e
  modifier to preg_replace (which has been replaced with
  preg_replace_callback). Without these changes, loganalyzer does not
  load at all, so the chance of regression is zero.
