Python 3.5 破坏了我的 apt

Question

Ubuntu 16.04 当我在系统故障后从备份恢复系统时，我的 apt 损坏了。

当我尝试使用 apt 时，例如：

$ sudo apt install pyroom 
Setting up python3 (3.5.1-3) ...
running python rtupdate hooks for python3.5...
dpkg-query: package 'rhythmbox-plugins' is not installed
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.
Traceback (most recent call last):
  File "/usr/bin/py3clean", line 210, in <module>
    main()
  File "/usr/bin/py3clean", line 196, in main
    pfiles = set(dpf.from_package(options.package))
  File "/usr/share/python3/debpython/files.py", line 53, in from_package
    raise Exception("cannot get content of %s" % package_name)
Exception: cannot get content of rhythmbox-plugins
error running python rtupdate hook rhythmbox-plugins
dpkg: error processing package python3 (--configure):
 subprocess installed post-installation script returned error exit status 4
Errors were encountered while processing:
 python3
E: Sub-process /usr/bin/dpkg returned an error code (1)

当我检查我的公寓列表时：

$ apt list python3.5

Listing... Done

python3.5/xenial-updates,xenial-security,now 3.5.2-2ubuntu0~16.04.1 amd64 [installed,automatic]

当我尝试重新配置时，出现错误：

$ sudo dpkg --configure -a
Setting up python3 (3.5.1-3) ...
running python rtupdate hooks for python3.5...
dpkg-query: package 'rhythmbox-plugins' is not installed
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.
Traceback (most recent call last):
  File "/usr/bin/py3clean", line 210, in <module>
    main()
  File "/usr/bin/py3clean", line 196, in main
    pfiles = set(dpf.from_package(options.package))
  File "/usr/share/python3/debpython/files.py", line 53, in from_package
    raise Exception("cannot get content of %s" % package_name)
Exception: cannot get content of rhythmbox-plugins
error running python rtupdate hook rhythmbox-plugins
dpkg: error processing package python3 (--configure):
 subprocess installed post-installation script returned error exit status 4
dpkg: dependency problems prevent processing triggers for gnome-menus:
 gnome-menus depends on python3:any (>= 3.1~); however:
  Package python3 is not configured yet.

dpkg: error processing package gnome-menus (--configure):
 dependency problems - leaving triggers unprocessed
Errors were encountered while processing:
 python3
 gnome-menus

我可以做什么来解决这个问题？

Answer 1

我花了几天时间寻找解决方案。 我调查了当前不同的包依赖关系：

$ apt list python3.5
Listing... Done
python3.5/xenial-updates,xenial-security,now 3.5.2-2ubuntu0~16.04.1 amd64 [installed,automatic]

但打破了依赖性：

Python 3.5.1-3

。

我删除了

Python 3.5.1

依赖的软件包并重新安装了它们。

然后运行：

$ sudo dpkg --configure -a

我得到了成功的结果。

Answer 2

通过删除目录 /usr/share/python3/runtime.d 中的 .rtupdate 文件并重新安装 python3 来修复。
