I have just updated my ISPConfig 3.1.1p1 installation (on Ubuntu 16.04.1) to version 3.1.2. All went well, but I got the message "Metronome XMPP SSL server certificate is not renewed." I ran the command specified – (cd /etc/metronome/certs && make localhost.key && make localhost.csr && make localhost.cert && chmod 0400 localhost.key && chown metronome localhost.key) – but got the messages: make: 'localhost.key' is up to date. make: 'localhost.csr' is up to date. make: 'localhost.cert' is up to date. Does this mean that the certificate files are now up to date, i.e. the update has succeeded, or were they already up to date – in which case why did I get the warning?
