使用 do-release-upgrade 时“/var/run/utmp: No such file or directory”

Question

Linux 新手在这里。我最近订购了我的第一个（非托管）VPS 运行 Ubuntu 10.04。我成功地通过 SSH 连接 (PuTTY) 升级到 12.04，但现在要升级到 12.10 版本时遇到了一些麻烦。这正是我所做的：

sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade
sudo reboot

sudo do-release-upgrade -c

Checking for a new Ubuntu release.
New release '12.10' available.
Run 'do-release-upgrade' to upgrade to it.

sudo do-release-upgrade

几秒钟后，由于找不到“/var/run/utmp”，安装过程停止：

root@vm3593:~# sudo do-release-upgrade
Checking for a new Ubuntu release
Get:1 Upgrade tool signature [198 B]
Get:2 Upgrade tool [1200 kB]
Fetched 1200 kB in 0s (0 B/s)
authenticate 'quantal.tar.gz' against 'quantal.tar.gz.gpg'
extracting 'quantal.tar.gz'
/var/run/utmp: No such file or directory

所以我试过：

cd /
sudo cat /dev/null > /var/run/utmp
sudo reboot

它修复了丢失的文件问题（是的！）。

不幸的是，设置仍然遇到以下错误：

File
"/tmp/update-manager-ZdDbE2/DistUpgrade/DistUpgradeController.py",
line 1616, in fullUpgrade
if not self.prepare():
File
"/tmp/update-manager-ZdDbE2/DistUpgrade/DistUpgradeController.py",
line 429, in prepare
self._sshMagic()
File
"/tmp/update-manager-ZdDbE2/DistUpgrade/DistUpgradeController.py",
line 299, in _sshMagic
"Do you want to continue?") % port)

File "/tmp/update-manager-ZdDbE2/DistUpgrade/DistUpgradeViewText.py",
line 216, in askYesNoQuestion
res = sys.stdin.readline().decode(ENCODING, "backslashreplace")

TypeError: decode() argument 1 must be string, not None
=== Command detached from window (Sat Aug  3 20:26:10 2013) ===
=== Command terminated with exit status 1 (Sat Aug  3 20:26:10 2013) ===

我能做什么？

请记住，我对此完全陌生。

引用帖子：

正在升级...（耶！）尝试：

sudo LC_ALL=C.UTF-8 sudo do-release-upgrade

或者

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

前者为我做到了。
