Package: cups-filters-core-drivers Version: 1.28.6-1 Severity: normal Dear Maintainer,
I've seen some misbehavior from my printer, and tried to remove and add it back again. This failed, with the symptoms described in https://unix.stackexchange.com/questions/276736/cups-adding-printer-fails-with-unable-to-get-list-of-printer-drivers-success that is, no matter what interface I use -- KDE, Gnome or the web via localhost:631 -- I get the same error when trying to find drivers for the printer: Unable to get list of printer drivers: Success Following the advice on that page, I tried to see if removal of one of the files in /usr/lib/cups/driver can help me get faster results, and I found that the guilty script was /usr/lib/cups/driver/driverless I then tried to run this script in isolation, and got: $ time /usr/lib/cups/driver/disabl/driverless list DEBUG: Started ippfind (PID 19070) Failed to get info about driverless support.
