Ubuntu 14.04 远程升级："TypeError"

Question

一天中的好时光！我正在尝试升级 Ubuntu 14.04，但出现以下错误：

ub14:~$ do-release-upgrade -d
Checking for a new Ubuntu release
Get:1 Upgrade tool signature [836 B]                                           
Get:2 Upgrade tool [1 265 kB]

extracting 'xenial.tar.gz'

Traceback (most recent call last):
  File "/tmp/ubuntu-release-upgrader-ohuj5xpk/xenial", line 8, in <module>
    sys.exit(main())
  File "/tmp/ubuntu-release-upgrader-ohuj5xpk/DistUpgrade/DistUpgradeMain.py", line 228, in main

    MARKER_EXPR = originalTextFor(MARKER_EXPR())("marker")
TypeError: __call__() missing 1 required positional argument: 'name'

所有需要的东西都已完成：

ub14:~$ sudo apt-get update; sudo apt-get upgrade; sudo apt-get dist-upgrade
ub14:~$ sudo apt-get install update-manager-core

<- 没关系。

问题最可能的原因：有一次我尝试升级Ubuntu 14.04，但忘记在电池完全放电之前重启系统。从那时起，每次尝试更新时都会出现 TypeError: __call__() missing 1 required positional argument: 'name'。从 GUI 更新也是不可能的 - 它只是在按下 "Upgrade" 按钮时关闭 window，仅此而已。可能有人已经解决了同样的问题，这个信息可能会有用。

以后有没有什么办法可以解决这个问题，而且没有任何副作用（我知道把MARKER_EXPR()改成MARKER_EXPR("")的技巧，但是没有关于这方面的信息-升级过程中或之后的影响）？提前谢谢您！

我遇到了同样的问题。做 sudo pip uninstall pyparsing 然后 sudo pip install pyparsing 为我解决了它。
