从 13.04 更新到 13.10 时，do-release-upgrade 因 decode() 中的 UnicodeDecodeError 而崩溃

Question

我刚刚尝试从 13.04 升级到 13.10，但在控制台中收到以下错误

Checking for a new Ubuntu release
authenticate 'saucy.tar.gz' against 'saucy.tar.gz.gpg' 
extracting 'saucy.tar.gz'
Traceback (most recent call last):
  File "/tmp/user/0/ubuntu-release-upgrader-xnzjbd/saucy", line 10, in <module>
    sys.exit(main())

    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf8' codec can't decode byte 0x9f in position 3: invalid start byte

这是我在update-managergui 中得到的

do-release-upgrade crashed on UnicodeDecodeError in decode(): 'utf8' codec can't decode byte 0x9f in position 3 : invalid state

Answer 1

查看sources.list.d 中是否有包含二进制垃圾（python unicode 解码器在其上吹散块）的任何点文件（以句点开头的文件）。我遇到了同样的问题，当我从 /etc/apt/sources.list.d/ 中删除点文件时，它又工作了。

对于遇到类似问题的人来说，最简单的解决方案是：

export LC_ALL=C.UTF-8
export LANG=C.UTF-8
do-release-upgrade

十分简单。UTF-8这适用于与任何类型的安装相关的许多类似问题。相信我！
