所以我想在 Ubuntu 的 WSL2 中安装 Firefox。现在，使用
sudo apt install firefox
给出了这个输出：
Building dependency tree... Done
Reading state information... Done
The following NEW packages will be installed:

此时尝试启动 Firefox 将会失败：
Command '/usr/bin/firefox' requires the firefox snap to be installed.
Please install it with:
snap install firefox
一旦我运行上述 snap 命令，我就会得到以下信息：
error: cannot communicate with server: Post "http://localhost/v2/snaps/firefox": dial unix /run/snapd.socket: connect: no such file or directory
有人能帮我吗？我不是 Linux 专家。

快速回答：
使用您的浏览器查看：

简而言之， （如果你已经完成了前两步，可能需要跳过它们）：
sudo snap remove firefox
sudo apt remove firefox
sudo add-apt-repository ppa:mozillateam/ppa
# Create a new file, it should be empty as it opens:
sudo gedit /etc/apt/preferences.d/mozillateamppa
# Insert these lines, then save and exit
Package: firefox*
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 501
# after saving, do
sudo apt update
sudo apt install firefox # or firefox-esr
答案2
System doesn't have a working snapd, skipping
看起来您可以：
- 使用较旧的 WSL2 版本
- 或者尚未在 WSL2 上启用 Systemd
Snap 现在可通过启用 Systemd 功能在 WSL2 上的 Ubuntu 上获得支持，如我的答案在这里。
但是，请考虑一下您是否真的需要这个：
- 正如我在回答中提到的那样，启用 Systemd 会产生并不总是需要的额外开销。
- Windows 版本的 Firefox 可能是一个更好的选择（除非您确实需要测试某些特定于 Ubuntu 或 Linux 的 Firefox 功能）。
- 另一个答案中提到的 PPA 也是一个有效的替代方案。
