Instalando o pacote contendo glib.h

Question

Estou tentando compilar o código que usa o glib.h. Eu encontrei na internet que o pacote libglib2.0-dev contém. Mas não consigo instalá-lo.

Aqui está a saída do meu console:

> sudo apt-get install libglib2.0-dev

Accept this solution? [Y/n/q/?] 

Quando eu digito 'y', não faz nada. Quando eu seleciono 'n', me propõe desinstalar ~ 1000 pacotes.

Eu não sei como conseguir este pacote.

    

Answer 1

Como primeiro passo, você deve remover 2.48.2-0ubuntu1 versão de libglib2.0-0 com este comando:

sudo dpkg -r --force-all libglib2.0-0

Depois disso, você deve instalar libglib2.0-0 e consertar pacotes quebrados:

sudo apt update
sudo apt install -f
sudo apt install libglib2.0-0 

Finalmente, você pode instalar:

sudo apt install libglib2.0-dev

    

Answer 2

De qualquer lugar (provavelmente um PPA instalado em algum momento), você tem arquivos de pacote armazenados em cache para libglib2.0-0 e libglib2.0-bin salvos localmente. Eles são uma versão mais recente do que os dos repositórios oficiais atuais e incompatíveis com eles.

Para esvaziar o cache do seu pacote local e impedir que esses pacotes em cache sejam instalados, você pode opcionalmente (não absolutamente necessário e talvez não tão eficaz quanto desejado) executar

sudo apt clean

Depois disso ou como única etapa, você pode informar apenas apt as versões a serem instaladas manualmente:

sudo apt install libglib2.0-dev libglib2.0-0=2.48.0-1ubuntu4 libglib2.0-bin=2.48.0-1ubuntu4
