I am trying to install opendmarc on an Ubuntu 18.04.5 server.

During apt-get install opendmarc I get:

Job for opendmarc.service failed because the control process exited with error code. See "systemctl status opendmarc.service" and "journalctl -xe" for details. invoke-rc.d: initscript opendmarc, action "start" failed. ● opendmarc.service - OpenDMARC Milter
Loaded: loaded (/lib/systemd/system/opendmarc.service; disabled; vendor preset: enabled) Active: activating (auto-restart) (Result: exit-code) since Thu 2020-10-08 09:58:18 UTC; 13ms ago Docs: man:opendmarc(8) man:opendmarc.conf(5) Process: 9643 ExecStart=/usr/sbin/opendmarc (code=exited, status=127)

I tried installing libopendmarc-dev and got the same

If I try to run opendmarc I get:

opendmarc: error while loading shared libraries: libopendmarc.so.2: cannot open shared object file: No such file or directory

It appears I don't have libopendmarc.so.2. I assumed it would be installed with libopendmarc-dev but apparently not.

How can I install it?

  • You may have a libopendmarc.so , probably somewhere in /usr/lib. In that same directory, create a symbolic link from libopendmarc.so to libopendmarc.so.2 and try again. This happens all the time (I don't know why). – Jos Oct 08 '20 at 11:15
  • Thanks. I hadonly libopendmarc.a in /usr/lib but creating a link from that to libopendmarc.so.2 results in: opendmarc: error while loading shared libraries: /usr/lib/libopendmarc.so.2: invalid ELF header – bayswaterbill Oct 08 '20 at 11:43

Solved by purging opendmarc, libopendmarc-dev, and also libopendmarc2 which I had previously overlooked, and then re-installing opendmarc, libopendmarc-dev and libopendmarc2 again.

This gave me the following symlinks in /usr/lib:

lrwxrwxrwx  1 root root     21 Oct  1 12:51 libopendmarc.so.2 -> libopendmarc.so.2.0.2
-rw-r--r--  1 root root  47784 Oct  1 12:51 libopendmarc.so.2.0.2
