debathena-lprng cron job causes daily mail with error to be sent

Reported by: kchen Owned by: jdreed
Priority: low Milestone: Fall 2010
Component: printing Keywords:
Cc: zev Fixed in version:
Upstream bug:


I get daily mail from two Debathena machines with:

2010-01-06-06:28:43.020 abra Init_tempfile: bad tempdir '/var/spool/lpd/%P'

One is a jaunty machine, and one is a hardy machine. (Hmm... actually, I haven't gotten mail from the jaunty machine in half a month, but it's possible MIT is eating it. I'll focus this bug report on the hardy machine, which is still sending me mail.)

kchen@abra:~$ ls -l /etc/cron.daily/debathena-lprng
-rwxr-xr-x 1 root root 1241 2008-06-17 13:50 /etc/cron.daily/debathena-lprng

kchen@abra:~$ dpkg -l debathena-lprng*

/ Name Version Description

ii debathena-lprng 3.8.28dfsg.1-1.1ubuntu2debathena5~ubuntu8.04 lpr/lpd printer spooling system
ii debathena-lprng-config 1.8~ubuntu8.04 Printing configuration for Debathena
ii debathena-lprng-no-server-config 1.3~ubuntu8.04 Remove lprng's cron job and init script

It looks like debathena-lprng-no-server-config is supposed to remove the cron job. One thing I just noticed is:

kchen@abra:~$ dpkg -S debathena-lprng-no-server-config | grep diversion
diversion by debathena-lprng-no-server-config from: /etc/cron.daily/lprng
diversion by debathena-lprng-no-server-config to: /usr/share/debathena-lprng-no-server-config/etc++cron.daily++lprng

Should /etc/cron.daily/debathena-lprng be diverted in addition to /etc/cron.daily/lprng? Or not installed? (I don't actually know what the cron job is supposed to do... I just know it sends me mail with an error every day.)

  • Component changed from -- to printing

debathena-lprng-no-server-config is an outdated package that pre-dates debathenifying LPRng.

These days, /etc/cron.daily/debathena-lprng should be suppressing that e-mail by means of this patch we insert as part of the debathenification process:

    # lprng's cron job generates mail to root each day if you're not
    # running a server.  Fix this problem by making the cron script
    # conditional on the existence of /etc/printcap, just as the
    # init.d script is.
    perl -ne 'print; /#.*main/ && print "[ -f /etc/printcap ] || exit 0\n";' \
      -i debian/debathena-lprng.cron.daily

Unfortunately, cupsd writes out a dummy /etc/printcap file for some reason, so I'm honestly not entirely sure how that ever worked.

Just deleting that job entirely would be the easy workaround - we'll see if we can come up with something better.

We should delete the job and move on.

Fixed in r24474 and r24475. The cron job won't run if /etc/printcap contains the text "automatically generated by cupsd".

Updated to not start erroring out when the printcap file doesn't exist

I actually just started seeing this problem on the 18th (running Karmic). Further, the email is actually getting sent to my MIT mail address:

To be clear, I've already installed the latest debathena-lprng and have only /recently/ started seeing the problem.

I can't reproduce this, on multiple machines. If this persists, please send /etc/printcap and the output of the cron job run with -x
