在 Ubuntu 20.04 (Focal) 上，我能够使用这个问题通过常规 Gnome VPN 管理来管理我的 WireGuard VPN 连接。但是，这在 22.04（Jammy）中不再起作用。插件构建得很好，我可以导入我的配置文件（如果我使用，它可以工作wg-quick up，所以我不认为这是一个配置文件问题），新的 VPN 配置出现在 VPN 列表中。但是，尝试激活它会导致“激活网络连接失败”并且无法连接到服务器。
以下是尝试连接时的系统日志：

答案1
有同样的问题。这里的 shell 命令（https://www.reddit.com/r/WireGuard/comments/us1blx/comment/i9klpio/?utm_source=share&utm_medium=web2x&context=3) 对我来说很好用。至少现在右上角的下拉菜单中显示了连接。在“设置”对话框中，它仍然缺失。
编辑：
nmcli connection import type wireguard file "/path/to/wg0.conf"
nmcli connection modify wg0 connection.id "home-vpn"
nmcli connection show home-vpn
导入配置后，它将不会显示在 Gnome 网络设置中。
为了解决每次启动后自动激活的连接的问题，您可以随后编辑连接nm-connection-editor并停用相关选项。

对我有用的是使用这个 gtk 客户端。

我之前尝试过所有其他方法，但到目前为止都没有效果。这个客户端解决了我需要的所有问题。它没有与 nm 集成，但仍然是一个很棒的工具。
