之前我尝试snort通过执行以下操作来打开cd /etc/snort，一切正常。然后我升级了我的 Ubuntu，现在无论我何时这样做cd /etc/snort，它都会显示bash: cd: /etc/snort: No such file or directory。
因此我尝试snort通过以下方式进行安装sudo apt-get install snort。但它显示：

snort is already the newest version (2.9.7.0-5build1).

After this operation, 0 B of additional disk space will be used.
Do you want to continue? [Y/n] Y

有人能帮我吗？我是 Ubuntu 的新手。
