我是新手，对 Linux 了解不多，但今天我在电脑上安装了 Ubuntu 20.04，然后搜索了 Packet Tracer 7.3 版本，安装了 .deb 文件，提取并获取了我的文件。有一个问题：一旦我尝试运行该程序（通过终端，写入：
cd /opt/pt
./PacketTracer7
), i always get a different type of error, always reguarding my libraries. So i searched for an answer and found that command:
ldd PacketTracer7
that shows me the missing directories that Packet Tracer actually needs, and this came out:

有什么问题？为什么我遗漏了这么多库？我该如何安装它们？我必须一个一个地安装它们吗？
谢谢您的任何建议。

由于各种依赖关系，安装数据包跟踪器可能会非常麻烦。
我首选的方法是使用这个脚本： https://github.com/Retinazer/packettracer-installer
提前通知一下，思科刚刚发布了 Packet Tracer 8 :)

要获取这两个文件所需的内容，它们位于我的 Kubuntu 20.10 上的 libqt5script5 和 libqt5scripttools5 包中。apt-file 是一个很棒的小程序，它允许您找到包含此想法所需文件的包。
