There must be more output to that when not wrapped. It seems it complains about a bad Restart setting and therefor it gets into "Loaded: error (Reason: Invalid argument)"
Now the tomcat8 in Xenial doesn't even have a service file that could be broken. It still uses a sysV init file and systemd picks it up via generators. Did you yourself add a tomcat8 service file? Is there a tomcat8.service file somewhere? If so who owns it: $ dpkg -S <filename> What is the source of your tomcat8 package and its content? $ apt-cache policy tomcat8 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1740424 Title: package tomcat8 8.0.32-1ubuntu1.4 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/tomcat8/+bug/1740424/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
