每次运行lpr或时lpq，都会收到此错误消息：
p11-kit: invalid config filename, will be ignored in the future: /etc/pkcs11/modules/gnome-keyring-module.dpkg-remove
命令仍然运行正常，但总是出现错误。如何才能停止生成错误消息？
文件内容：
# The file is installed/loaded from the default module p11-kit directory
module: gnome-keyring-pkcs11.so
# And where to store and lookup trust objects
x-trust-store: pkcs11:library-manufacturer=GNOME%20Keyring;serial=1:XDG:DEFAULT
x-trust-lookup: pkcs11:library-manufacturer=GNOME%20Keyring
删除该文件将会消除错误消息。
