替换基础组件安装源（可选）
首次在Ubuntu系统上安装OpenFDE时，需要获取完整的OpenFDE的安装源并配置证书。
当然，如果不是首次安装，可以跳过该小节，直接进入安装OpenFDE
...
因为OpenFDE依赖一些基础组件，因此替换基础安装源为国内镜像能加速安装。
修改/etc/apt/source.list
如果是noble则修改为如下：
...
| 代码块 |
|---|
sudo apt-get install wget gpg |
2.2 从官网下载密钥文件并解密至本地
| 代码块 |
|---|
wget -qO- http://openfde.com/keys/openfde.asc | gpg --dearmor > packages.openfde.gpg |
2.3 将解密后的密钥文件拷贝到本地apt工具的密钥文件夹下
| 代码块 |
|---|
sudo install -D -o root -g root -m 644 packages.openfde.gpg /etc/apt/keyrings/packages.openfde.gpg |
2.4 配置OpenFDE的软件源地址
| 代码块 |
|---|
sudo echo \
"deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/packages.openfde.gpg] http://openfde.com/repos/ubuntu/ \
"$(. /etc/os-release && echo "$VERSION_CODENAME")" main" | \
sudo tee /etc/apt/sources.list.d/openfde.list > /dev/null |
2.5 删除下载的密钥文件
| 代码块 |
|---|
rm -f packages.openfde.gpg |
