在 Ubuntu 上VirtualBox 更新vagrant up失败并出现以下错误后：

There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: ["hostonlyif", "ipconfig", "vboxnet2", "--ip", "10.160.0.1", "--netmask", "255.255.255.0"]

Stderr: VBoxManage: error: Code E_ACCESSDENIED (0x80070005) - Access denied (extended info not available)
VBoxManage: error: Context: "EnableStaticIPConfig(Bstr(pszIp).raw(), Bstr(pszNetmask).raw())" at line 242 of file VBoxManageHostonly.cpp

使用的版本：

• 流浪者2.2.14
• virtualbox-6.1 6.1.28-147628~Ubuntu~eoan
• Ubuntu 20.04.3 LTS

我想将microk8s与私有注册表一起使用，但拉取映像不起作用（我正在使用自签名证书）：

这是我的containerd-template.tom：
