I've got a Ubuntu 16.04 LTS dev server setup and today it crashed. I found the following log entry in syslog right before the crash.

Mar 6 05:36:01 SERVERNAME CRON[7172]: (sogo) CMD (/usr/sbin/sogo-tool expire-sessions 30 >/dev/null 2>&1; /usr/sbin/sogo-ealarms-notify >/dev/null 2>&1)

But when I try to type:

sudo apt-get remove sogo-tool

I get:

E: Unable to locate package sogo-tool

When I try:

sudo apt-get remove sogo

I get:

Package 'sogo' not installed, so not removed

But when I try running:


I get:

The program 'sogo-tool' is currently not installed. You can install it by typing: sudo apt install sogo

So I started checking my crontabs, and there's nothing sogo-related in there either! I checked monthly, weekly, daily, and hourly. No sogo...

So it appears a piece of software that isn't installed has a cron that crashes the server, and the commands for uninstalling it all don't work. Any ideas?

  • Found it! There was a file in /etc/cron.d called "sogo." – Justin Grimes Mar 6 at 22:42
