I had this problem with an HP Deskjet 722C, running Ubuntu 7.10. I seem
to have fixed the problem, but the advice was not perfectly clear to me.
I did the following:
[EMAIL PROTECTED]:~$ sudo /etc/init.d/apparmor stop
[sudo] password for michael:
Unloading AppArmor profiles : done.
[EMAIL PROTECTED]:~$ sudo gedit /etc/apparmor.d/usr.sbin.cupsd
However, the suggested addition of:
" /etc/* r,
at the end of the list of all the other /etc/ exceptions"
is ambiguous for someone who has no idea what these commands are all
about, or even what language they are in. There were two possible places
where there was a list of "etc" strings. The first is a follows:
# nasty, but we limit file access pretty tightly, and cups chowns a
# lot of files to 'lp' which it cannot read/write afterwards any
# more
capability dac_override,
/bin/bash ixr,
/bin/dash ixr,
/bin/hostname ixr,
/dev/lp* rw,
/dev/ttyS* rw,
/dev/usb/lp* rw,
/etc/cups/ rw,
/etc/cups/** rw,
/etc/foomatic/* r,
/etc/gai.conf r,
/etc/shadow m,
/etc/passwd m,
/etc/group m,
/etc/papersize r,
/etc/printcap rwl,
/etc/ssl/** r,
/etc/* r,
@{PROC}/net/ r,
The second is this:
# separate profile since this needs to write into /home
/usr/lib/cups/backend/cups-pdf {
#include <abstractions/base>
#include <abstractions/fonts>
#include <abstractions/nameservice>
#include <abstractions/user-tmp>
capability chown,
capability fowner,
capability fsetid,
capability setgid,
capability setuid,
/bin/dash ixr,
/bin/bash ixr,
/etc/papersize r,
/etc/cups/cups-pdf.conf r,
/etc/* r,
@{HOME}/PDF/ w,
Note that I added the "/etc/* r," in two places. The printer seems to work
well. How reliably I cannot say. However, since this was done in cook book
fashion, I have no idea if both "/etc/* r," insertions were necessary, or
desirable.
