dpkg: erro processando o pacote unit-tweak-tool (--configure)

Question

quando eu executo o apt-get install, o apt-get upgrade, o apt-get -f install, ele sempre retorna isto:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
0 upgraded, 0 newly installed, 0 to remove and 4 not upgraded.
1 not fully installed or removed.
Need to get 0 B/333 kB of archives.
After this operation, 0 B of additional disk space will be used.
dpkg: error processing package unity-tweak-tool (--configure):
 package is in a very bad inconsistent state; you should
 reinstall it before attempting configuration
Errors were encountered while processing:
 unity-tweak-tool

O que há de errado? Eu tento todos os comandos como apt-get remover, limpar, limpar e não há nenhum efeito e ainda retornar erro.

[EDIT] Eu tento reinstalar a ferramenta de ajuste de unidade, mas ela retorna:

Answer 1

Executar

sudo apt-get install --reinstall unity-tweak-tool

conforme recomendado pela mensagem de erro. Você provavelmente apagou alguns dos arquivos manualmente e quebrou o pacote.

    

Answer 2

você pode tentar isso:

sudo apt-get purge unity-tweak-tool
sudo -i
sudo apt-get update --fix-missing
sudo apt-get upgrade

e pode funcionar bem assim.
