升级到 Ubuntu 16.04 do-release-upgrade 失败

当我尝试使用以下命令升级到 Ubuntu 16.04（从 15.10 开始）：

sudo do-release-upgrade

我收到以下错误：

Traceback (most recent call last):

有任何想法吗？

答案1

遇到了类似的问题（同样的错误，但字符不同）。解决方法是编辑 /var/lib/dpkg/status 并删除有问题的字符。在我的情况下，它是 davmail 包。

还发现它已经存在了一段时间并引起了其他问题： https://lists.ubuntu.com/archives/foundations-bugs/2012-November/125607.html

“维护者：Mickaël Guessant”那个（ë）不是用 UTF-8 编码的 :(

您可能遇到过类似的问题。如果您懂一些 Python，您可以编写一个脚本来检测您的问题出在哪里。

答案2

这是一个已确认的错误，目前影响的人数还不足以修复。如果您受到影响，请订阅此错误报告并发表评论：

根据我的经验，受错误影响的人越多，错误被修复的机会就越大。
