falhou ao desinstalar postgres-xc

Question

Ao tentar configurar meu ambiente de trilhos para usar o postgresql, instalei erroneamente postgres-xc .

No entanto, ocorreu um erro na instalação, por isso, quando tentei remover o pacote, recebi o seguinte erro:

The following packages will be REMOVED:

Examine the log output.

dpkg: error while cleaning up:

Errors were encountered while processing:  
 postgres-xc  
E: Sub-process /usr/bin/dpkg returned an error code (1)  

A pesquisa no Google mostra que algumas soluções apontam para editar o arquivo /var/lib/dpkg/info/postgres-xc.prerm para incluir exit 0 , mas isso não funciona. Além disso, observe que nem mesmo reconhece esse arquivo.

    

Answer 1

Abra o arquivo usando o comando

sudo nano /var/lib/dpkg/status

depois remova o pacote quebrado postgres-xc e o bloco inteiro de informações sobre ele e salve o arquivo.

faça

apt-get install -f

apt-get update
