Python 3.5 broken my apt

Ubuntu 16.04 When I restore my system from backup after system fault, I got broken apt.

When I trying use apt, for example:

$ 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)

When I check my apt list:

$ apt list python3.5

Listing... Done

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

When I try reconfigure, I got errors:

$ sudo dpkg --configure -a
Setting up python3 (3.5.1-3) ...

dpkg-query: package 'rhythmbox-plugins' is not installed

dpkg: error processing package gnome-menus (--configure):

What can I do to fix that?

I spent several days to find solution. I investigated that currently different package dependencies:

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

but broken dependency: Python 3.5.1-3.

I deleted packages depended from Python 3.5.1 and installed them again.

Then run:

$ sudo dpkg --configure -a

I got successful result.
