最近不知道设置了什么,现在在ubuntu16.04上使用apt安装软件都失败:

$ sudo apt-get upgrade

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 libglib2.0-dev : Depends: libglib2.0-0 (= 2.48.1-1~ubuntu16.04.1) but 2.48.2-0ubuntu1 is installed
                  Depends: libglib2.0-bin (= 2.48.1-1~ubuntu16.04.1)
E: Unmet dependencies. Try using -f.

ps: sudo apt install ipython也是报同样的错误

然后我按照提示进行修复:

$ sudo apt-get -f install
Extracting templates from packages: 100%
Preconfiguring packages ...
dpkg: error processing package libglib2.0-dev (--remove):
 package is in a very bad inconsistent state; you should
 reinstall it before attempting a removal
Errors were encountered while processing:
 libglib2.0-dev
E: Sub-process /usr/bin/dpkg returned an error code (1)

准备卸载libglib2.0-dev,却无法卸载,而且报错信息和上面一样,提示reinstall,但是apt命令没有reinstall参数

$ sudo apt-get remove libglib2.0-dev
...
After this operation, 10.5 MB disk space will be freed.
Do you want to continue? [Y/n] y

libglib2.0-dev处于bad inconsistent state所以要reinstall,但是却无法卸载那么该怎么进行reinstall,google以及在其他社区找了很久也没找到答案,请问这是什么原因?


补充

$ sudo apt-get check

解决方案

之前google的姿势不对,问题的关键是 package is in a very bad inconsistent state; you should reinstall it before attempting a removal

参考资料强制卸载sudo dpkg --remove --force-remove-reinstreq libglib2.0-dev,但是又出现了新的问题,由于包不兼容python3,所以还要sudo ln -s /usr/bin/python2.7 /usr/bin/python,这样一来就只能使用python2.7,然后各种软件配置重新改。

比如youcompleteme要改成python3等等。

let g:ycm_server_python_interpreter = '/usr/bin/python3'
let g:ycm_python_binary_path = '/usr/bin/python3'

libglib2.0-dev는 libglib2.48.1-1 및 libglib2.0-bin에 의존합니다

그러나 시스템에는 이미 더 높은 버전인 libglib2.48.2-0 > 2.48.1-1이 설치되어 있습니다.

libglib2.48.2-0을 제거하고 sudo apt-get install package=version 명령을 사용하여 지정된 libglib 버전을 설치합니다
