Description Robin A. Meade 2016-12-17 00:28:55 UTC

1. went to http://localhost:631/printers/<queuename>

2. Selected "Modify Printer"

3. Entered My username and password when promPted by Basic Authentication dialog

4. Received "Forbidden" message

Expected to be able to administer printers through the CUPS web interface, since, when I created my account during installation, I checked "Administrator" option, which put me in the "wheel" group.

POSSIBLE SOLUTION

I fixed this on my system, by:

1. sudo vim /etc/cups/cups-files.conf

2. Added 'wheel' to the SystemGroup line:

# Administrator user group, used to match @SYSTEM in cupsd.conf policy rules...
# This cannot contain the Group value for security reasons...
SystemGroup sys root wheel

I think this should be the default so we have one less hurdle when troubleshooting printer problems.

ADDITIONAL DETAILS

For reference, on Ubuntu 16.10, this line is:

SystemGroup lpadmin

and I was in this group by default.

Hi Robin,

I am not sure if it is good to add 'wheel' group to SystemGroup by default, so I asked upstream about it. I will tell you outcome.

Comment 2 Zdenek Dohnal 2017-01-05 10:36:50 UTC

Upstream said they are only historical reasons for it and they are no longer actual as other operating systems are adding their groups. So I will add 'wheel' as default.

Comment 3 Robin A. Meade 2017-01-05 18:36:48 UTC

Great. This will make administering printers easier and meet expectations of what a system administrator should be able to do. Thank you Zdenek.
