Lubuntu 13.04 - CUPS fails to start on bootup
Lubuntu 13.04:
CUPS is not starting at boot-up. I discovered this when attempting to install the printer with this new
install. I then started CUPS from the terminal, was able to install the printer, and print. However, on
restarting the computer, the service again fails to start. How do I conﬁgure this service to always
automatically start on bootup?
There is a Desktop Sessions Settings dialog of automatically started applications, but CUPS is not
included there.

Re: CUPS fails to start on bootup
open a terminal and give me the output of
Code:
head /etc/init/cups.conf
I've not SEEN it conﬁgured wrong before, but I've never not not seen CUPS start on startup before
either

I'm looking at the output I gave, and I am not a coder, but it looks to me like for cupsd to start avahi-
daemon must be started ﬁrst? Am I right or wrong?

avahi simply advertises services--in this case shared printers. It should not cause cupsd to fail. CUPS
does not have a direct dependecy but "recommends" avahi-daemon, which means it should be able to
run without avahi-daemon.
If you are running 13.04, try the following:
Code:
sudo apt-get update
sudo apt-get upgrade
reboot
Then check your printers.

As to the cups log ﬁles, here is part of the error log, with output from a session earlier this afternoon:
Code:
W [26/Apr/2013:13:23:26 -0700] CreateProfile failed: org.freedesktop.DBus.Error.ServiceUnknown:The
W [26/Apr/2013:13:23:26 -0700] CreateDevice failed: org.freedesktop.DBus.Error.ServiceUnknown:The
E [26/Apr/2013:13:38:54 -0700] [cups-driverd] Bad driver information file "/usr/share/cups/drv/cup
Not sure these are that relevant to the cups-not-running problem - Lubuntu 12.10 on another
computer shows similar errors (except for the bad driver information ﬁle line) and it prints normally.
Thanks for pointing out the logs.

I already tried this earlier. No eﬀect.
Yes, cupsd does not need avahi-daemon, and can run without it, but from the structure of the code, it
appears to me that cupsd will not start unless avahi-daemon has been started ﬁrst. Am I wrong on
that interpretation?
Next, I just found that avahi-daemon is not installed with Lubuntu 13.04:
Code:
dn@Alexa:~$ apt-cache policy avahi-daemon
avahi-daemon:
Installed: (none)
Candidate: 0.6.31-1ubuntu3
Version table:
0.6.31-1ubuntu3 0
500 http://us.archive.ubuntu.com/ubuntu/ raring/main i386 Packages
It's not installed on my Lubuntu 12.10 installation either, and Lubuntu 12.10 prints normally. But on
12.10, the cups.conf does not include any reference to avahi-daemon - here is the cups.conf from
Lubuntu 12.10:
Code:
dn@Roxanne:~$ head /etc/init/cups.conf
respawn
I think I need to install avahi-daemon, or else change the code to remove reference to it.
Comment?
reboot
Then check your printers.

Well, I edited cups.conf and removed the line referring to avahi-daemon. I was correct - this was
stopping cupsd from starting. Tested and confirmed this solution. Printing on Lubuntu 13.04 now
works.
Now, anyone who downloads and installs Lubuntu 13.04 from the same iso is going to be affected
by the same problem.
The iso is at:
http://cdimage.ubuntu.com/lubuntu/re...sktop-i386.iso
and has a misconfigured cups.conf that will prevent the cups-daemon from starting unless fixed.
The corrected cups.conf begins:
Code:
respawn
Thanks to Synoc and tgalati4 for your input.
