Description Dark Shenada 2018-01-07 16:50:35 UTC 
Description of problem:
SELinux is preventing /usr/lib/cups/backend/cups-pdf from 'write' accesses on the sock_file system_bus_socket.

*****  Plugin catchall (100. confidence) suggests   **************************

若您相信 cups-pdf 應該預設允許在 system_bus_socket sock_file 上作 write 存取。
Then 您應將此回報為錯誤。
您可產生本機模組，以允許這項存取。
Do
立刻允許此存取，請執行：
# ausearch -c 'cups-pdf' --raw | audit2allow -M my-cupspdf
# semodule -X 300 -i my-cupspdf.pp
