我正在尝试构建一个 Rust 终端应用程序。我正在这里在文档中。我运行 snapcraft。它尝试连接 archive.ubuntu.com 和 security.ubuntu.com，但几分钟后失败了。完整输出为：

Package udev 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
However the following packages replace it:
systemd
E: Unable to locate package dirmngr
E: Package 'udev' has no installation candidate
E: Unable to locate package fuse
An error occurred when trying to execute 'apt-get install dirmngr udev fuse --yes' with 'LXD': returned exit code 100.
我曾尝试解决该问题，我曾看到过类似的解决方案这一个，但它不起作用。我认为这是因为 snap 在受限的环境中工作。
我还尝试删除 lxd 并重建我的 snap 以便它重新安装并重新配置 lxd 但这也不起作用。
我该如何解决这个问题？
提前致谢。
