usando ppa-purge (com / sem -i) resulta na sugestão de remoção de mais de 100 pacotes Tenho certeza que ESTÃO DISPONÍVEIS no repositório padrão do Ubuntu

Question

Eu insensatamente adicionei o kxstudio ppa há algum tempo atrás. Tudo parecia bem por alguns meses, então os problemas começaram a aparecer e não passaram de uma dor desde então. Eu enviei vários relatórios de bugs e perdi muito tempo apenas para descobrir que eles foram principalmente devido aos pacotes 'atualizados' do kxstudio. Eu agora desejo remover o ppa, e cada pacote já instalado por ele, removendo o pacote se ele não estava lá antes, ou revertendo para outra versão disponível se estiver no repositório do Ubuntu.

Eu usei o ppa-purge, com e sem a opção -i, e recebo algo assim:

sudo ppa-purge -i kxstudio-team

Tenho certeza de que alguns desses pacotes são muito importantes, mas não entendo por que eles precisam ser removidos. Outras sugestões de resolução de dependência removem ainda mais pacotes!

Alguém pode lançar alguma luz sobre isso?

    

Answer 1

Primeiro, exclua manualmente o ppa usando o seguinte comando:

sudo rm /etc/apt/sources.list.d/kxstudio*

Agora, use "apt-pinning" para dar prioridade à sua distro atual, independentemente do número da versão do pacote. Primeiro, crie um arquivo:

sudo nano /etc/apt/preferences

e copie / cole o seguinte no arquivo substituindo "trusty" pela sua versão atual do ubuntu:

Package: *
Pin: release a=trusty*
Pin-Priority: 1001

Pressione CTRL + O e depois pressione ENTER para salvar o arquivo e pressione CTRL + X sair.

Agora, limpe os pacotes específicos do kxstudio:

sudo apt-get purge kxstudio-artwork kxstudio-default-settings kxstudio-desktop kxstudio-desktop-kde4 kxstudio-welcome

Em seguida, para aplicar o downgrade:

sudo apt-get update
sudo apt-get dist-upgrade

Answer 2

Pode estar disponível nos repositórios do Ubuntu, mas pode haver uma versão mais nova ou instalada do PPA que você instalou. Você pode querer verificar os pacotes afetados e talvez reinstalá-los a partir de fontes do Ubuntu.
