Please would you

1. Set debug logging: cupsctl --debug-logging

2. Empty the error_log: >/var/log/cups/error_log

3. touch /usr/share/cups/ppd-updaters/*

4. apt-get --reinstall install cups

Compress the error_log and attach it, a transcript for the output of the
last command and your cupsd.conf to your reply.

Regards,
