我的包管理器出了什么问题？

我的系统每次安装新软件后都会遇到错误：

sh: 1: /bin/echo: Permission denied
E: Problem executing scripts DPkg::Post-Invoke '/usr/bin/test -e /usr/share/dbus-1/system-services/org.freedesktop.PackageKit.service && /usr/bin/test -S /var/run/dbus/system_bus_socket && /usr/bin/gdbus call --system --dest org.freedesktop.PackageKit --object-path /org/freedesktop/PackageKit --timeout 4 --method org.freedesktop.PackageKit.StateHasChanged cache-update > /dev/null; /bin/echo > /dev/null'
E: Sub-process returned an error code
