I can confirm that upgrading from 3.5.1.dfsg-2.1ubuntu1.1 to 3.5.1.dfsg-2.1ubuntu1.3 (from ppa:ubuntu-security-proposed/ppa) fixes this issue on xenial.
Installing ppa:ubuntu-security-proposed/ppa's 3.5.1.dfsg-2.1ubuntu1.3 on xenial without a previous nagios3 installed is OK too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1690380 Title: "Cannot open log file '/var/log/nagios3/nagios.log' for reading" error from nagios web UI when view alert history etc. To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nagios3/+bug/1690380/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
