Debian Wheezy: reinstalar o apache2

Question

O pacote apache2 foi quebrado no meu servidor Debian, então eu iniciei desinstalando todo o pacote relacionado ao apache2. Agora tudo parece estar desinstalado corretamente.

dpkg -l | grep 'apache' não retorna nada

No entanto, parece que não consigo instalar o apache2 ...

com apt-get :

sudo apt-get install apache2

Como posso resolver esse problema e fazer o Apache funcionar novamente?

Answer 1

De acordo com aptitude , uma dependência do Apache chamada libaprutil1 é instalada em uma versão mais recente do que a disponível nos repositórios:

The following packages have unmet dependencies: 
libaprutil1-dbd-sqlite3 : Depends: libaprutil1 (= 1.4.1-3) but
1.5.4-1+b1 is installed.  libaprutil1-ldap : Depends: libaprutil1 (= 1.4.1-3) but 1.5.4-1+b1 is installed.

Você pode tentar descobrir a origem desse pacote com apt-cache policy :

apt-cache policy libaprutil1

libaprutil1=1.5.4-1+b1 parece vir do sid do Debian ... você por acaso tentou instalar o Apache dos repositórios sid? Isso não parece ser uma boa idéia ... se você quiser uma versão mais recente do Apache, eu recomendaria a upgrade para o Debian jessie .

Por favor, anexe a saída de apt-cache policy à sua pergunta (e enquanto você está nisso, também a saída de cat /etc/apt/sources.list ); É possível que seu sources.list contenha URLs dos repositórios wheezy e sid, o que seria uma coisa ruim.

Você pode tentar remover o pacote libaprutil1 mais recente:

aptitude purge libaprutil1

E tente instalar o Apache novamente:

aptitude install apache2

    

Answer 2

libaprutil1 é o pacote que está causando problemas (e provavelmente sua dependência, libapr1 ). Você precisa:

• remova a linha testing/security do seu /etc/apt/sources.list ;

• atualize os caches de pacotes:

  sudo apt-get update
  

• remova libaprutil1 e libapr1 :

  sudo aptitude remove libaprutil1 libapr1
  

  (e qualquer pacote que dependa deles)

• em seguida, instale apache2 :

  sudo aptitude install apache2
