I think I broke mon, is it possible to install correctly?

I'm using Ubuntu 12.04, can't move to 14.04 or anything because that's what the IT guys installed on the system

anytime I try to do a sudo apt-get install <package>, somewhere along the line I'll get the following messages:

Code:

0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

1 not fully installed or removed.

and then

Code:

Setting up mon (1.2.0-4) ...

 * The user mon, required to run mon does not exist.

invoke-rc.d: initscript mon, action "start" failed.

dpkg: error processing mon (--configure):

 subprocess installed post-installation script returned error exit status 1

Errors were encountered while processing:

 mon

E: Sub-process /usr/bin/dpkg returned an error code (1)

I've tried the following at one point or another in my last 2 days of searching:

sudo apt-get autoclean
sudo apt-get remove --purge mon
sudo dpkg --configure mon
sudo apt-get install -f

as well as apt-get install. No matter what, it shows me as having that '1 not fully installed or removed' and then that stuff at the bottom regarding "E: Sub-process"

I can do a sudo apt-get update without issue or error message, as well as sudo apt-get check (nothing really happens with that). sudo apt-get upgrade shows me the above message

I found this:

Code:

sudo apt-cache policy mon

and got this output:

Code:

mon:

  Installed: 1.2.0-4

  Candidate: 1.2.0-4

  Version table:

 *** 1.2.0-4 0

        500 http://10.185.137.7/ubuntu/desktop/ precise/universe amd64 Packages

        100 /var/lib/dpkg/status

I did this:

Code:

sudo dpkg -l | grep "mon"

and got this

Code:

pF  mon                                        1.2.0-4                              monitor hosts/services/whatever and alert about problems

ii  mon-client                                  1.2.0-1                              modules for interfacing with the mon package

(along with about 5,000 "common" and "daemon")

so it would seem that mon is actually installed?

i found out about checkinstall,

Code:

sudo aptitude install checkinstall

Code:

Errors were encountered while processing:

 mon

E: Sub-process /usr/bin/dpkg returned an error code (1)

A package failed to install.  Trying to recover:

so basically, it seems like I cannot install or remove anything, and I'm not sure what to do about this. I cannot point to anything that could've caused this in the first place. Obviously I did something, but I darn sure don't know what it is.

Any help greatly appreciated. Sorry if I didn't provide enough info, I'm obviously a newbie and I'm trying to read the man page for mon but it is completely overwhelming right now. Thanks for any help or pointers or...something.

Can you explain the following above?

1) Do you own this computer or is it a company computer and its their policy you must remain on 12.04?
b) Did they install it but you bought it as a home computer?

2) If IT installed the system then why haven't you reported your problems to IT?

Some install(er) issue. ???

"Setting up mon (1.2.0-4) ...
* The user mon, required to run mon does not exist."

Might have to get sources and build.

Humm. ubuntu site seem to have an issue.

If so this will confirm that it is:-

Code:

dpkg -L mon

thank you for the assistance. My responses inline below.

answers:
1) Answer: it's a company computer
2) Answer: I would prefer to reduce downtime and figure it out myself (err....with some help. :) )

so build mon from source? I can figure that out, I'll give that one a try

almost positive I did that yesterday, but forgot to report. When I get to office in the morning I'll check.

thanks again everyone!

yeah, definitely. I got a ton of filepaths, /etc, /etc/mon, /etc/mon/auth.cf, /etc/mon/mon.cf, etc

so there's a lot of files presently 'owned' by mon

There is a contradiction, user mon does exist. Who owns mon executable?

assuming the executable is the one in /usr/sbin, then root owns it. It's showing x for each permission, so I think that's the proper one

The tar ball that you download should come with a README or an INSTALL file to tell you how to install it.

http://www.howtogeek.com/105413/how-...rce-on-ubuntu/
http://www.webmonkey.com/2010/02/com...m_source_code/

Before you attempt to build from source use all the other suggestions first.

I still think this is the place to start.

right, but isn't the user mon just a user created by the mon daemon specifically to use mon? regardless, it's not in /etc/passwd

dpkg: error processing mon (--configure):
subprocess installed post-installation script returned error exit status 1

I seems to be saying to me that dpkg can't correctly use the configure script for some reason. What that is I don't know.

The configure script may have an error in it.
It's happened to me:-

Maybe researching the error message will lead to a solution-
