Veda's questions

我刚刚从 ubuntu 19.10 更新到 ubuntu 20.04。现在，当我使用网络管理器中的 openconnect 连接到 vpn 时，我的 resolve.conf 不再更新。

这可以正常工作：

sudo openconnect -u 用户https://server

我看到 resolv.conf 正在更改。所以是客户端问题。

在 /etc/NetworkManager/NetworkManager.conf 我有 dns=none 使用 resolv.conf

/etc/resolv.conf 是一个文件，没有符号链接到 /run/systemd/resolve/resolv.conf。我确实检查了 /run/systemd/resolve/resolv.conf 是否被任何东西更新，但这也没有得到更新。

这是来自系统日志：

我查看了升级前的旧系统日志，其中有如下行：

NetworkManager[1245]: <info>  [1590386910.5867] vpn-connection[,"vpn",14:(vpn0)]: Data:   Internal DNS: 10.0.0.1
NetworkManager[1245]: <info>  [1590386910.5867] vpn-connection[,"vpn",14:(vpn0)]: Data:   Internal DNS: 10.0.0.2

所以现在这些都不见了。有人知道如何解决这个问题吗？

我确实尝试使用 dns=auto 来使用 systemd-resolve 但这也有同样的问题。systemd-resolve --status 报告没有用于 vpn 连接的 dns 服务器，以及 /run/systemd/resolve/resolv.conf。

注意：我匿名了所有的 IP 地址和主机名等。

我已经在我的统一菜单中锁定了 byobu 图标。当我单击它时，我希望有一个用于此图标的窗口。

但这不会发生。实际发生的是，当我第一次单击它时，它会打开一个终端窗口，菜单中有它自己的新图标（所以现在我有一个看起来没有启动的 byobu 图标，以及一个不需要的终端图标）。如果我再次单击 byobu 图标，它会打开一个新的终端窗口。

自从我买了一台新笔记本电脑（ubuntu 15.10）以来，我遇到了这个问题。在我的旧笔记本电脑上，它按预期工作（ubuntu 14.04 LTS）。

我怎样才能解决这个问题？

编辑：来自评论：

/usr/share/applications/byobu.desktop 中的 Exec 行：

Exec=env TERM=xterm-256color byobu

运行 docker.io 时出现以下问题：

运行 modprobe bridge nf_nat br_netfilter 失败并显示消息：modprobe：警告：找不到模块 br_netfilter。

我尝试运行modprobe br_netfilter结果：

modprobe br_netfilter
modprobe: FATAL: Module br_netfilter not found.

如何在我的系统上安装 br_netfilter？

谢谢！

没有返回任何东西。也许不相关，但我有这个目录：/lib/modules/3.16.0-49-generic/kernel/net/bridge/netfilter它包含几个 .ko 文件，但不包含 br_netfilter。
