But I don't think much of the above is relevant apart from Ubuntu details.
I am trying to install spider.

I downloaded spider-v2.3.0 extracted the tar and ran the install.
Installation appeared to work and auto-started, but then stopped with error message:

Process: 66505 ExecStart=/usr/local/bin/spiderd (code=exited, status=255/EXCEPTION)

It then auto-restarts and produces the same error.

A manual start produces the following message:

**************************************************************
********************     ERROR       *************************
**************************************************************
Failed to start the service, please check console output
and log file (/var/log/messages or /var/log/syslog), contact
support if necessary: {link to spider removed}

The log files don't help me, just giving the entries:

Jun 19 16:39:48 mail systemd[1]: /lib/systemd/system/spiderd.service:20: Standard output type syslog is obsolete, automatically updating to journal. Please update your unit file, and consider removing the setting altogether.

and

Jun 19 16:39:48 mail systemd[321535]: spiderd.service: Failed to determine user credentials: No such process
Jun 19 16:39:48 mail systemd[321535]: spiderd.service: Failed at step USER spawning /usr/local/bin/spiderd: No such process
Jun 19 16:39:48 mail systemd[1]: spiderd.service: Main process exited, code=exited, status=217/USER
Jun 19 16:39:48 mail systemd[1]: spiderd.service: Failed with result 'exit-code'.

I did not know what to do, so I repeated the whole procedure on another server with the same versions of iRedMail, Ubuntu and spider, and, no surprise, got exactly the same results.

What am I doing wrong?
