我正在尝试通过 tar 文件夹中提供的可执行脚本在 Lubuntu 16.04.2 LTS 上安装 Cisco Packet Tracer 7.0。以下是终端输出：
root@Brick:~# pwd
/root
root@Brick:~# cd /home/riccardo/Downloads
root@Brick:/home/riccardo/Downloads# ls
PacketTracer70 PacketTracer70_64bit_linux.tar.gz
root@Brick:/home/riccardo/Downloads# cd PacketTracer70
root@Brick:/home/riccardo/Downloads/PacketTracer70# ls
art backgrounds bin eula.txt extensions help install languages lib
saves set_ptenv.sh Sounds templates tpl.linguist tpl.packettracer
root@Brick:/home/riccardo/Downloads/PacketTracer70# sudo ./install
[displays eula]
Do you accept the terms of the EULA? (Y)es/(N)o
Y
You have accepted the terms to the EULA. Congratulations. Packet Tracer will now be installed.
Enter location to install Cisco Packet Tracer or press enter for default [/opt/pt]:
Installing into /opt/pt
Not able to create and copy files to /opt/pt
Should we try to gain root access with sudo? [Yn] Y
mkdir: cannot create directory ‘/opt/pt’: No such file or directory
Not able to gain root access with sudo
Exiting installation
root@Brick:/home/riccardo/Downloads/PacketTracer70#
请注意，我以 root 身份登录。使用以下命令运行脚本
sudo ./install
或者
sudo bash ./install
或者
sudo su
./install
产生相同的结果。
在这里我复制并粘贴了安装文本脚本的内容：
#!/bin/bash
Thanks to Felix Wolf ([email protected]) for providing this install script.
Thanks to Paul Fedele for providing script to check/download 32-bit library on a 64-bit machine

通过手动创建 /opt 文件夹解决了这个问题：
sudo mkdir /opt
在运行安装脚本之前。
感谢@GunnarHjalmarsson 提供这个答案（你可以在上面的评论中找到他的原始答案）。
