Public bug reported:
I just upgraded a machine to Ubuntu Bionic. I was using icingaweb2 to monitor
a server before the upgrade.
After the upgrade when I try to login to icinga2 I get an error:
Fatal error: Uncaught ErrorException: session_name(): Cannot change session
name when session is active in
/usr/share/php/Icinga/Web/Session/PhpSession.php:97 Stack trace: #0 [internal

Steps to reproduce
1. Navigate to http://servername/icingaweb2/authentication/login
2. Enter valid username and password
3. Click login button
The error message is displayed as above.
According to the machine these are the versions of the relevant
packages:
ii icingaweb2 2.4.1-1 all simple and
responsive web interfa
ii libapache2-mod-php7.2 7.2.7-0ubuntu0.18.04.2 amd64
I did some research and think I have found that Icingaweb2 was not
compatible with php7.2 until June this year:
