linux安装软件时/usr/lib/python2.7/site-packages/urlgrabber/grabber.py文件异常

linux安装软件时，经常出现以下异常信息

Traceback (most recent call last):
  File "/usr/libexec/urlgrabber-ext-down", line 75, in <module>
    main()
  File "/usr/libexec/urlgrabber-ext-down", line 61, in main
    fo = PyCurlFileObject(opts.url, opts.filename, opts)
  File "/usr/lib/python2.7/site-packages/urlgrabber/grabber.py", line 1258, in __init__
    self._do_open()
  File "/usr/lib/python2.7/site-packages/urlgrabber/grabber.py", line 1589, in _do_open
    self._do_grab()

    self._do_perform()
  File "/usr/lib/python2.7/site-packages/urlgrabber/grabber.py", line 1517, in _do_perform
    raise KeyboardInterrupt
KeyboardInterrupt

解决办法

vim /usr/lib/python2.7/site-packages/urlgrabber/grabber.py

在第1510行左右，将

elif errcode in (42, 55, 56):

改为

elif errcode == 42:

重新安装软件即可
