pacemaker fails to install/upgrade if the user hacluster already exists and is not a system user.

[Jose Marquez]

Binary package hint: update-manager

Updating Kubuntu Karmic to Lucid; received error saying I could not install pacemaker.

Thanks for taking the time to report this bug and helping to make Ubuntu better. Could you please add the log files from '/var/log/dist-upgrade/' to this bug report as separate attachments? Thanks in advance.

[Jean-Baptiste Lallement (jibel)]

Thanks for the logs affecting to pacemaker.

The relevant error is
Setting up pacemaker (1.0.8+hg15494-2ubuntu2) ...
addgroup: The group `haclient' already exists as a system group. Exiting.
Warning: The home dir /var/lib/heartbeat you specified already exists.
adduser: The user `hacluster' already exists. Exiting.
dpkg: error processing pacemaker (--configure):

[Ante Karamatić (ivoks)]

That's not the reason why it failed to install. adduser exits with 0 if user already exists. Something else is the cause.

[Ante Karamatić (ivoks)]

Jose any chance you still have that broken?

[Jose Marquez (ubuntu-hackwater)]

Hi Ante,

I just tried to install pacemaker again, and it again chokes on the warning:

Possibly of interest: I only received this error when I upgraded my work laptop from Karmic to Lucid. I don't have the option to do a clean install of Lucid on that laptop. However, on my personal laptop, I did do a clean install of Lucid Lynx. That clean install does not attempt to install pacemaker automatically, though it does manage to install successfully if I manually select it.

Could you give me output of:

DPKG_DEBUG="developer" dpkg --configure -a

Thanks

Oh, sorry.

Jose,

and what is the output of the command:
$ sudo sh -x /var/lib/dpkg/info/pacemaker.postinst configure

[Jose Marquez (ubuntu-hackwater)]

user@host:~$ sudo sh -x /var/lib/dpkg/info/pacemaker.postinst configure
+ set -e
+ addgroup --system haclient
addgroup: The group `haclient' already exists as a system group. Exiting.
+ adduser --system hacluster --ingroup haclient --home /var/lib/heartbeat
Warning: The home dir /var/lib/heartbeat you specified already exists.
adduser: The user `hacluster' already exists. Exiting.

[Jean-Baptiste Lallement (jibel)]

That's weird because as Ante said adduser should exit with status 0

What the output of
$ getent passwd hacluster

[Jose Marquez (ubuntu-hackwater)]

user@host:~$ getent passwd hacluster
hacluster:x:1001:122:Heartbeat System Account:/usr/lib/heartbeat:/bin/false

[Jean-Baptiste Lallement (jibel)]

adduser exits with status 1 in this situation because the postinst script asks to create a system user but the user already exists as a non system user.

Jose, I don't know the detailed configuration of your system and what the use of the hacluster user on your system, so take my advice for what it is and adapt to your specific system setup.The easiest way to workaround your problem is to change the uid of the user hacluster to something in the range of system's uid (100 to 999 by default). The command is
$ usermod -u NEW_UID hacluster

choose a non existent uid. Then try performing the installation again.

[Jose Marquez (ubuntu-hackwater)]

That did the trick. Thanks, Jean-Baptiste; I changed user UID to 128, which was not currently being used (after a quick inspection of UIDs in my passwd file) and pacemaker's installation was able to finish.

That's hilarious. Good catch!

Thank you guys for debugging.

Thank you for taking the time to report this bug. In an effort to keep an
up-to-date and valid list of bugs to work on, I have reviewed this report
to verify it still requires effort and occurs on an Ubuntu release in
standard support, and it does not.

It is unfortunate that we were unable to resolve this defect, however
there appears to be no further action possible at this time. I am
therefore moving the bug to 'Incomplete'. If you disagree or have
new information, we would be grateful if you could please add a comment
stating why and then change the status of the bug to 'New'.

[Steve Langasek (vorlon)]

The Precise Pangolin has reached end of life, so this bug will not be fixed for that release
