我已经全新安装了 Ubuntu 18.04.3 LTS。我正在尝试安装 Wi-Fi 适配器来访问互联网。安装失败：
yoav@yoav-System:~/Documents/LINUX/Linux$ sudo chmod +x install.sh
yoav@yoav-System:~/Documents/LINUX/Linux$ ./install.sh

我不知道如何导航到 install.sh 文件所在的目录。
编辑 2：尝试安装 build-essential 包：sudo apt-get install build-essential
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package build-essential is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'build-essential' has no installation candidate
apt-get 需要在线吗？在安装此驱动程序之前，我一直处于离线状态。
答案1
看起来您没有“make”可执行文件。安装 build-essential 包：
sudo apt-get install build-essential
然后重试。
