Vagrant配置开关字符编码问题

Question

今天我运行了vagrant provision，但是出现了以下错误：

Package configuration┌──────────────────────────┤ Configuring grub-pc ├──────────────────────────┐│││ 
The GRUB boot loader was previously installed to a disk that is no
││ longer present, or whose unique identifier has changed for some reason.   
││ It is important to make sure that the installed GRUB core image stays in  
││ sync with GRUB modules and grub.cfg. Please check again to make sure
││ that GRUB is written to the appropriate boot devices.
││││ If you're unsure which drive is designated as boot drive by your BIOS,    
││ it is often a good idea to install GRUB to all of them.
││││ Note: it is possible to install GRUB to partition boot records as well,  
││ and some appropriate partitions are offered here. However, this forces   
││ GRUB to use the blocklist mechanism, which makes it less reliable, and   
││ therefore is not recommended.
││││<Ok>│││└───────────────────────────────────────────────────────────────────────────┘

但是，出乎意料的是，它开始以一种非常奇怪的编码方式打印堆栈跟踪...

终端提示返回的编码与之前一样！所有输入都被转换成了该编码（虽然大写字母照常显示）。

我的问题是：为什么Vagrant会改变我的终端窗口编码，这是否与GRUB错误有关？

我使用的是Macbook Pro。

这是在StackExchange网络的其他地方提出你的问题之前：http://askubuntu.com/questions/325872/ubuntu-unattended-apt-get-upgrade-grub-install-dialog - opyate

你是否曾经确定过这种行为的根本原因？ - John Claus

Answer 1

如果您正在使用 apt-get upgrade/dist-upgrade，请尝试以下命令：sudo DEBIAN_FRONTEND=noninteractive apt-get -y -o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confold" upgrade。

在Raspbian的QEMU chroot中执行时，我会得到这个错误。按照@deeperx下面的答案进行别名设置后一切正常。 - Mike Mackintosh

Answer 2

我已经为此编写了一个函数。只需将其复制粘贴到您的配置脚本中即可：

function aptget {
  # to prevent encoding problem
  sudo DEBIAN_FRONTEND=noninteractive apt-get -y \
    -o Dpkg::Options::="--force-confdef" \
    -o Dpkg::Options::="--force-confold" \
    $@
}

aptget update
aptget upgrade

注意：我曾将这篇文章作为对@gustavohenrique答案的评论发布，但它并不适合作为评论的格式。所以，尽管这是一个重复的答案，我还是将其发布为了一个答案。它更像是一种补充说明。对于造成的不便，请谅解。
