在 ubuntu 16.04 上安装 unetbootin 时出现问题

我跑了

sudo add-apt-repository ppa:gezakovacs/ppa

得到以下结果，但最后 4 行出现错误：-

gpg: keyring `/tmp/tmp8k7uho4o/secring.gpg' created
gpg: keyring `/tmp/tmp8k7uho4o/pubring.gpg' created
gpg: requesting key FC91AE7E from hkp server keyserver.ubuntu.com

如果您只是想轻松将映像刻录到 USB 驱动器。

您可以使用蚀刻机作为替代方案unetbootin

我喜欢这个简单的用户界面

韓國可以为你做

  • 制作一个简单的 Ubuntu 安装驱动器（仅限 Live）
  • 使用 Ubuntu 制作持久实时驱动器
  • 擦除驱动器（用零覆盖第一个兆字节或整个驱动器）
  • 将驱动器恢复为标准大容量存储设备

如果你想要最新版本，请从不稳定存储库安装
