Public bug reported:
In Ubuntu 20.04, with `tomcat9-9.0.31-1ubuntu0.1` (latest) package,
`logrotated` is not able to write to `/var/log/tomcat/catalina.out`
In Ubuntu 22.04, with `tomcat9-9.0.58-1` (latest) package, `logrotated`
is not able to rotate `/var/log/tomcat/catalina.out`
The reason of missing `catalina.out` in Ubuntu 20.04 is that the
`/var/log/tomcat` does not have group write permission. Therefore `syslog` user
which executes `rsyslogd` is not able to write to `/var/log/tomcat` folder.
A common problem between Ubuntu 20.04/22.04 is that the
`/etc/rsyslog.d/tomcat9.conf` file does not have the following setting:
`fileOwner="tomcat"` (which exists in upstream Debian `tomcat9` package
supplied `/etc/rsyslog.d/tomcat9.conf` file)
Because of the missing `fileOwner` setting, the `catalina.out` is
created with `syslog:adm` ownerships. However the
`/etc/logrotate.d/tomcat9` has `su tomcat adm` directive. Therefore the
`logrotated` is not able to truncate the `/var/log/tomcat/catalina.out`
This causes logrotate to copy the contents of
`/var/log/tomcat/catalina.out` to as if it would be rotated. As
`catalina.out` is never truncated, each rotated file ends up having the
contents of `catalina.out` from the beginning of the tomcat
installation. This causes the log sizes to keep increasing as no actual
log rotation is being done.
