CUPS: 426 – Upgrade Required
As I was installing my printer on my Ubuntu 6.06 Dapper LTS server with CUPS I noticed the following error:
426 Upgrade Required
After some research I came to the conclusion that CUPS, by default, tries to use SSL whenever possible. So, with this 426 error, you are redirected to the SSL domain. Chances are, you haven’t configured SSL properly, if at all.
In my case, I didn’t want to configure SSL. To get rid of this problem, the key lies in editing your configuration files ( /etc/cups/cupsd.conf ) and adding the following line:
DefaultEncryption Never
There are several options, Never, IfRequired and Required. By setting this to Never, SSL will never be enforced. Just restart your CUPS server with
$ /etc/init.d/cupsys restart
and you’re good to go.
hi,
you’ve got a little mistake, the configuration file to edit is /etc/init.d/cupsd.conf, not /etc/init.d/cupd.conf.
thanks for the trick!
@Oscar: Thanks. I’ve updated the post.

Great…Thanks.
as a matter of fact, the conf file of Cups it’s located at /etc/cups/cupsd.conf
good information though.
THANK YOU! this was driving me nuts while trying to configure cups on my zaurus (running openbsd where the config file requires encryption by default).
Thanks for the fix. I did not know what to do. :-)
This just proves that it IS important to post seemingly trivial bits of information on the net.
Great info! Helped me big time! Thanks :)
Thanks a lot! This did the trick, and my printer is now served over the network by CUPS! :) Yikes!
Hi man! Thanks a lot! :) That’s works!
