Plesk Unable to exec utility listmng: Cannot find grep program System error 2: No such file or directory [closed]

Question

I have a little problem with my plesk installation at the moment and unfortunately do not have enough knowledge to solve it on my own. I would therefore be glad if I could get a hint on this.

I tried to log in into my Plesk but I can't proceed due to the following error:

Internal error: Unable to exec utility listmng: listmng: listmng: Cannot find grep program System error 2: No such file or directory

File Unix.php

Line 147

Type PleskUtilException

I'm running Plesk 11.5.30 on Ubuntu 10.04. What's strange is that I didn't make any changes on the server lately. At least not that I'm aware of.

I tried running plesks "bootstrap.sh repair" and uninstalled the mailman but I keep getting the error.

When I run /opt/psa/admin/sbin/listmng via ssh I get the same error, so I guess it's not able to use the grep command. I don't know how to solve that problem though.

I'd appreciate any kind of help.

You might want to start off by looking if grep is on your system with grep -V which will reports the version (and if it exists in the path).

If grep is not there I would worry about the integrity of your operating system. Grep is pretty standard and normally always found in the path.

If grep is missing you might want to examine the path with export on a healthy system to see if essential system folders are missing from the path.

On my healthy Ubuntu 13.04 the path reports:

PATH="/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"

On this system the grep utility can be located in /bin and the system wide path is set in /etc/environment.

If you don't succeed using with troubleshooting the operating system / Plesk installation I would seriously consider contacting Plesk. There might be a cost to logging a ticket with them but at the same time the support for their product is excellent.

And finally you could try logging the problem on the Parallels forum (http://forum.parallels.com). Although it's technical community based support it's generally very active and you might even find a Parallels engineer lurking there. I have found that although ServerFault is a great systems administration Q&A site Plesk problem are better addressed elsewhere.
