Comment 19 for bug 82265

'cupsdAuthorize: Local authentication certificate not found!' is not caused by the drivers being at another place than usual. This should be independent of thw Gutenprint package.

Can you check whether you have the /opt/gutenprint directory when the LSB package of Gutenprint is installed? Or better when you cannot print with this package please post the result of

ls -lR /opt/gutenprint

The reference to cups-config in gutenprint.prerm is no problem, as if there is no cups-config, the script will simply work without the output of cups-config.

Can you install the LSB package of Gutenprint and uninstall it with

sudo dpkg -P -D2 gutenprint

and post the output here.

Make also sure that you use the newest version of the Gutenprint package from OpenPrinting (gutenprint-5.0.0.99.1-3lsb3.1.i486.rpm).
