我在 ubuntu 16.04 中安装了 packettracer6.2。安装成功，但是当我在终端中输入 packettracer 时，除了“启动 packettracer 6.2”之外什么也没有发生。我该如何解决这个问题？
答案1
首先检查您的系统完整性并安装所有升级：
sudo apt-get check
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install -f
假设你已经将 CPT 分布提取到~/Downloads/PacketTracer62。因此cd ~/Downloads/PacketTracer62
然后运行sudo ./install。
默认情况下它将安装到/opt/cpt，由安装程序运行apt-get，然后在中创建符号链接/usr/local/bin。
在安装过程中我收到有关包的错误消息lib32bz2-1.0，但安装后我可以packettracer在我的 64 位 Ubuntu 16.04 LTS 上启动。
看来apt-get您的机器上的该部分失败了。您可以尝试sudo ./install再次重新安装 CPT。或者手动安装所有需要的软件包：

并确保安装lib32bz2-1.0Trusty 遗漏的软件包
wget http://mirrors.kernel.org/ubuntu/pool/main/b/bzip2/lib32bz2-1.0_1.0.6-5_amd64.deb
sudo apt-get install ./lib32bz2-1.0_1.0.6-5_amd64.deb
并重新运行 CPT 安装（确认覆盖）：
sudo ./install
