dpkg: erro de análise

Estou recebendo esse erro desde os últimos dias ao instalar qualquer pacote do Centro de Software. Tentei substituir o arquivo de status por qualquer um dos arquivos de status de backup em/var/backups/, mas ainda obtive o mesmo erro.

dpkg: parse error, in file '/var/lib/dpkg/status' near line 114 package 'python-pkg-resources':
 `Depends' field, invalid package name `python:any': character `:' not allowed (only letters, digits and characters `-+._')

Devido à menor reputação, não consegui fazer upload da captura de tela, mas abaixo numerei as linhas conforme estão no arquivo de status.

104.Package: python-pkg-resources 
105.Status: install ok installed
106.Priority: optional 
107.Section: python

117.Description: Package Discovery and Resource Access using pkg_resources
118.The pkg_resources module provides an API for Python libraries to
119.access their resource files, and for extensible applications and
120.frameworks to automatically discover plugins.  It also provides
121.runtime support for using C extensions that are inside zipfile-format

Consigo instalar pacotes a partir do código-fonte, mas sempre que tento instalar pacotes do Software Center ou do Synaptic Package Manager, recebo este erro:

There seems to be a programming error in aptdaemon, the software that allows you to install/remove software and to perform other package management related tasks.
