o mesmo acontece quando tento limpar o postgres, o que está acontecendo aqui e como posso remover o postgres corretamente?

Seu problema

invoke-rc.d: initscript postgresql, action "start" failed.
dpkg: error processing package postgresql-common (--configure):
 subprocess installed post-installation script returned error exit status 1

Minha solução

oAtalho

sudo rm /etc/init.d/postgresql
sudo rm /etc/init/postgresql.conf
sudo apt-get remove postgresql

ou oLongo caminho

  • Abra o arquivo/var/lib/dpkg/info/postgresql-common.postinst

    sudo nano /var/lib/dpkg/info/postgresql-common.postinst

  • Pesquise a linha com o comando start:

    if [ -x "/etc/init.d/postgresql" ] || [ -e "/etc/init/postgresql.conf" ]; then
        invoke-rc.d postgresql start || exit $?
fi

  • comente o bloqueio

    # if [ -x "/etc/init.d/postgresql" ] || [ -e "/etc/init/postgresql.conf" ]; then
#        invoke-rc.d postgresql start || exit $?
# fi

  • Remova o pacote novamente.

    sudo apt-get remove postgresql

Explicação

Durante a remoção do postgresql, o script postgresql-common.postinsté chamado. O script tenta iniciar o serviço postgresqle falhará invoke-rc.d postgresql start(não me pergunte por quê).

Isto deve ser evitado. Ou alterando as condições pelas quais o código é executado. Ou pela remoção do próprio código.
