问题在于我的笔记本电脑是 32 位的，而这个软件是 64 位的吗？我应该将服务器更改为其他国家/地区吗？（我该怎么做？）
我怀疑答案是没有可用的 32 位版本，该 snap 会自动考虑我的处理器类型，因此 32 位通道中没有安装文件。
答案1
Brave 浏览器 snap 包已暂时停用。目前 Brave 浏览器官方网站上提供的在 Ubuntu 中安装 Brave 浏览器的说明如下。打开终端并输入：
sudo apt install apt-transport-https curl
curl -s https://brave-browser-apt-release.s3.brave.com/brave-core.asc | sudo apt-key --keyring /etc/apt/trusted.gpg.d/brave-browser-release.gpg add -
echo "deb [arch=amd64] https://brave-browser-apt-release.s3.brave.com/ stable main" | sudo tee /etc/apt/sources.list.d/brave-browser-release.list
sudo apt update
sudo apt install brave-browser
更新
brave浏览器Snap包已经重新提交到Snap Store，可以使用以下命令安装在所有当前支持的Ubuntu版本中：
sudo snap install brave
新的 Brave 浏览器会自动屏蔽广告和跟踪器，使其比您当前的浏览器更快、更安全。此软件包是官方的。

我怀疑使用 snap 是否是在 Ubuntu 上安装 Brave 的最佳方式，因为我按照该方法操作后遇到了更新问题。
我根据这里的建议卸载了 snap 版本https://snapcraft.io/brave：
我们建议使用以下说明下载 Brave：https://brave-browser.readthedocs.io/en/latest/installing-brave.html相反。此 Snap 由社区维护，可能不包含在最新的 Brave 版本中。
他们建议：
发布渠道安装
Ubuntu 16.04+ 和 Mint 18+
sudo apt install apt-transport-https curl curl -s https://brave-browser-apt-release.s3.brave.com/brave-core.asc | sudo apt-key --keyring /etc/apt/trusted.gpg.d/brave-browser-release.gpg add - source /etc/os-release echo "deb [arch=amd64] https://brave-browser-apt-release.s3.brave.com/ $UBUNTU_CODENAME main" | sudo tee /etc/apt/sources.list.d/brave-browser-release-${UBUNTU_CODENAME}.list sudo apt update sudo apt install brave-browser
答案4
对我来说，使用勇敢的网页后（https://brave-browser.readthedocs.io/en/latest/installing-brave.html#linux）安装我需要运行的勇敢浏览器：
root@localhost# sudo apt install brave-browser:amd64
代替：
root@localhost# sudo apt install brave-browser
