It would seem to me that the "adm" group (to which syslog seems to belong) lacks a write permission Indeed, rsyslog in Ubuntu runs as syslog:adm and needs special permissions to write to /var/log/tomcat9. This issue should be reported to Ubuntu. The tomcat9 package in Debian isn't affected by this issue because rsyslogd runs as root. > OK, I did it and the write permission was added to the adm group. I restarted Tomcat.... and it worked, the catalina.out file got created! However, after I restarted the whole Ubuntu, I discovered that the permissions went back to how there were (not write for adm). Why is that? The permissions on this directory are managed by systemd-tmpfiles. The tomcat9 package defines the expected permissions in /usr/lib/tmpfiles.d/tomcat9.conf and the permissions are enforced when the system starts. It's possible to override the default settings, you have to copy the configuration file to /etc/tmpfiles.d/ and change the permissions on /var/log/tomcat9 from 2750 to 2760: cp /usr/lib/tmpfiles.d/tomcat9.conf /etc/tmpfiles.d/ sed -i s/2750/2760/ /etc/tmpfiles.d/tomcat9.conf The write permissions for the adm group will then be persistent. Hi Emmanuel, Thanks a lot for your help, but unfortunately I think that something is still not working. I copied the file running the cp command, and then edited the created file to replace "2750" with "2760", then restarted Ubuntu.... But I still have the same problem, catalina.out never gets created. Then I tried editing the original file (/usr/lib/tmpfiles.d/tomcat9.conf) replacing "2750" with "2760", then restarted Ubuntu.... But I still have the same problem. I verified that the permissions stay correct, I mean giving write permission to the adm group after I restart Ubuntu, and that DOES work! When I perform a "ls -l /var/log/", this is what I see for the "tomcat9" directory: drwxrwS--- 3 tomcat adm 4096 Jun 23 11:31 tomcat9 Finally, I checked the syslog and this is what I found: Jun 23 12:27:43 ip-172-31-92-155 systemd: Starting Apache Tomcat 9 Web Application Server... Jun 23 12:27:43 ip-172-31-92-155 systemd: Started Apache Tomcat 9 Web Application Server.

It seems that rsyslogd is still unable to deal with "/var/log/tomcat9/catalina.out". What could be wrong now? Do you have any ideas?
