当尝试更新时，错误如下：
FATAL ERROR:
Both /lib/x86_64-linux-gnu/libselinux.so.1 and /usr/lib/x86_64-linux-gnu/libselinux.so.1 exist.
You can try correcting the errors reported and running again
/usr/lib/usrmerge/convert-usrmerge until it will complete without errors.
Do not install or update other Debian packages until the program
has been run successfully.
dpkg: error processing usrmerge package (--configure):
installed usrmerge package post-installation script subprocess returned error exit status 1
我尝试使用以下命令修复它：sudo apt -f install，sudo dpkg --configure -a，没有任何帮助，错误不会消失！告诉我你该如何解决它？
