Networking printing trouble with 18.04

Support & Help Requests Hardware

Hi,
not sure if I can really blame Mate for this. I moved from Ubuntu Unity 16.04 to Mate 18.04 via reinstall and now have trouble printing to the network printer (some sophisticated central windows server based printer queue system called Follow-me). The issue is that when I add the printer with the correct https address I cet a dialogue that asks for a password for user "negotiate". I have a user name and password but since it presets the user name field with "negotiate" there is no chance to successfully connect to the printer queue .

I checked /etc/cups/printer.conf and yes it is added: AuthInfoRequired negotiate
Removing that does not really help since it is overwritten with every job (attempt).

Anyone notice this too since the upgrade?

Hi @dietmarw,

start here but I am not sure if it will help?:

Thanks for trying but I’ve been already through all the standard help pages. This seems to be a very particular problem especially the “negotiate” setting. My only hope now is that somebody else had a similar experience AND found a solution to this.

I have the same problem but I could not find a solution yet.

Unfortunately I’m still stuck with the problem. Using print via email as a work around or using a windows machine for that. All sub-optimal and I really would prefer to be able to print directly again…

I have a similar problem in Ubuntu 18.04 and have reported the bug to Ubuntu at https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1783298 together with a possible work-around.

Thanks I will test that next week when back at work.

Hi.
so I tried the work around but after uncommenting the socket and disabling the cups.socket service I end up with

when trying to add a printer. So it looks like the socket service is still needed somehow.

Hi,
This is the request of a CUPS server authentication, which by default, has a value " Basic" in config. And you have to switch it off by doing the following:

sudo nano /etc/cups/cupsd.conf
change the value DefaultAuthType from Basic to None

sudo service cups restart

sudo usermod -aG lpadmin "UBUNTU USERNAME"

Hopefully can solve the issue.

Thanks
