package nfs-common (not installed) failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

Error is:

Setting up nfs-common (1:1.2.0-2ubuntu8) ...
statd start/running, process 12034
gssd stop/pre-start, process 12057
start: Job is already running: idmapd
invoke-rc.d: initscript idmapd, action "restart" failed.
dpkg: error processing nfs-common (--configure):
 subprocess installed post-installation script returned error exit status 1

Seems to be hitting this bit in upstart-job:

    PID=$(status "$JOB" 2>/dev/null | awk '/[0-9]$/ { print $NF }')
    if [ -z "$PID" ] && [ "$COMMAND" = "stop" ]; then
        exit 0
    elif [ -n "$PID" ] && [ "$COMMAND" = "start" ]; then
        exit 0
    elif [ -z "$PID" ] && [ "$COMMAND" = "restart" ]; then
        start "$JOB"
        exit 0
    fi

so status is not returning a PID, but 'start' is failing saying that it's already running.

Per submitter:
$ sudo status idmapd
idmapd start/running
$

That's not the output we should have there, idmapd shouldn't be "running" without a PID... so something is amiss.

So not a bug in nfs-utils.

I've just tested an install with the 9.10 RC for Mythbuntu both with and without NFS selected during install.

I believe that this issue is actually resolved now. It was most likely caused by mythbuntu-live-autostart depending upon nfs-common earlier in the cycle. This caused nfs-common to be installed, but messed up the cleanup of it's dependencies post-install if it was not selected for installation. Installing NFS manually later would result in an unusable NFS service due to these broken dependencies.

for me, solved by manually (vi) create user statd and group nogroup
