dpkg：不可恢复的致命错误（包“ java-common”的文件列表文件缺少最后的换行符）

Question

我正在尝试使用命令在Linux操作系统上安装软件包apt-get install ...。问题是我收到此错误：

Selecting previously unselected package liberror-perl.
dpkg: unrecoverable fatal error, aborting:
 files list file for package 'java-common' is missing final newline
E: Sub-process /usr/bin/dpkg returned an error code (2)

谷歌搜索的错误（甚至逐行），该解决方案似乎是“下载并安装缺少的包来解决依赖性”，因为它是点出在这里。问题是，当我尝试执行时，sudo apt-get -f install我仍然一次又一次地遇到相同的错误。有什么建议吗？如果无法使用apt-get，如何更改软件包？

Answer 1

我已经使用python脚本解决了问题：

#!/usr/bin/python


# 8th November, 2009
# update manager failed, giving me the error:
# 'files list file for package 'xxx' is missing final newline' for every package.
# some Googling revealed that this problem was due to corrupt files(s) in /var/lib/dpkg/info/
# looping though those files revealed that some did not have a final new line
# this script will resolve that problem by appending a newline to all files that are missing it
# NOTE: you will need to run this script as root, e.g. sudo python newline_fixer.py

import os

dpkg_path = '/var/lib/dpkg/info/'
paths = os.listdir(dpkg_path)
for path in paths:
path = dpkg_path + path
f = open(path, 'a+')
data = f.read()
if len(data) > 1 and data[-1:] != '\n':
    f.write('\n')
    print 'added newline character to:', path
f.close()  

使用命令运行脚本后sudo python name_script.py，问题得以解决：似乎某些文件已损坏。解决方案是在这里提出的
