[apparmor] [Bug 908864] Re: My Lexmark x2650 printer stopped working after upgrading to 11.10: Idle - File "/usr/local/lexmark/lxk08/bin/printdriver" has insecure permissions (0100775/uid=0/gid=2).

>I changed permissions on the folder '/usr/local/lexmark/lxk08/bin',
then everything seems to go on right way

could you explain how exactly did you change the permissions? with which
command or so...

I tried Ubuntu 11.04 and I can confirm that my printer works there too and in any previous Ubuntu release. so, the 
problem happened sometime between CUPS 1.4.6 and 1.5.0!

my behaviour is 99% the same as Nyjk's, but for me the red exclamation
mark next to the printer's icon never vanishes, but that one time when I
managed to remove it, the subsequent message was something like "no
connection to the printer", so this is the only difference between our
cases.

@John Johansen

I disabled apparmor at startup as you suggested in comment #10, so it is
not apparmor that causes this. do you agree to remove it from the
affected projects?

Title:
  My Lexmark x2650 printer stopped working after upgrading to 11.10:
  Idle - File "/usr/local/lexmark/lxk08/bin/printdriver" has insecure
  permissions (0100775/uid=0/gid=2).

Status in AppArmor Linux application security framework:
  New
Status in “cups” package in Ubuntu:
  Confirmed

Bug description:
  I used Ubuntu 9.04 for a long time and the driver available on the
  manufacturer's site:
  http://support.lexmark.com/index?page=content&id=DR860&actp=search&viewlocale=en_US&segment=SUPPORT&productCode=LEXMARK_X2650&locale=EN&userlocale=EN_US&searchid=1324929199490
  worked perfectly! after installing the newest Ubuntu, I can't even
  finish the installation process of the driver, the Setup says "no
  connection", even though there is connection to the printer, because
  it appears in the list of printers when introduced to the USB.

  from what I have learnt on the web, recent changes in Cups and
  AppArmor caused that the connection to a printer with 3rd party driver
  is often blocked. but this is too high a game for me to solve here...

  have tried in another machine too, the same result, which means that
  THIS PRINTER JUST STOPPED WORKING IN LINUX at all. That is sad. I have
  to go back to older Ubuntu's just for the printer!!!!!!!!!

  This is insane.

  See my debugging results.
