No meu Kubuntu 14.4 (que possui o python 2.7.6 como padrão), meu python está quebrado depois que tentei instalar o python 2.7.10 após criar a partir do código fonte do python.org com a ajuda de Como instalar a versão mais recente do Python no Debian separadamente ou melhoria? . Não consigo consertá-lo com os comandos padrão que suspeito que meu dpkg esteja de alguma forma confuso / quebrado em relação à instalação do python. Eu gostaria de corrigir o dpkg nesse aspecto. Eu suspeito que isso tem algo a ver com o arquivo /var/lib/dpkg/statuse /var/lib/dpkg/availablee /var/lib/dpkg/info/*particularily o primeiro. Eu acho que tenho que redefinir de dpkgalguma forma, mas eu realmente não sou especialista. A razão pela qual acho que isso é:
$ apt-cache policy python

>>> exit()A razão pela qual tentei instalar o python 2.7.10 é porque eu precisava dele para outro programa (por causa de problemas com o ssl / openssl do python 2.7.6), mas agora eu só quero reparar meu sistema - apenas deixe o python 2.7 .6.
O Técnico Completo
Comecei a tentar resolver isso perguntando no ubuntu /ubuntu/648424/muon-is-gone-after-change-of-python-issues-after-python-2-7-10-installation- ligado, mas não recebi nenhuma resposta lá. Talvez tenha sido a multidão errada. Eu tentei um pouco desde então e tenho uma idéia de qual é o problema, mas não sei as etapas para fazer isso.
Começou comigo não sendo capaz de instalar o muon com sudo apg-get install muon:
$ sudo apt-get install muon

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:
The following packages have unmet dependencies:
muon : Depends: apt-xapian-index but it is not going to be installed
E: Unable to correct problems, you have held broken packages.O conselho típico (por exemplo, de /ubuntu/118749/package-system-is-broken-how-to-fix-it ) não ajuda:
sudo apt-get autoremove

whereis python2.7ewhereis python?--prefix=/path/to/foldero./configurecomando./configure --prefix=/opt/python. Caso contrário, pode ter sido onde as coisas deram errado. Sem fornecer a--prefix=/opt/pythonpeça, você pode substituir a instalação em todo o sistema. Você seguiu exatamente essas instruções?Respostas:
Você instalou pacotes Python mais recentes do que a sua distribuição fornece. Por exemplo, você tem a
pythonversão 2.7.10-1 instalada, mas sua distribuição possui apenas a versão 2.7.5-5ubuntu3.O APT não faz o downgrade de pacotes, a menos que seja explicitamente instruído a fazê-lo. Por exemplo, se você tentar instalar um pacote que depende da versão exata do Python, ele não funcionará, porque o
pythonpacote não pode ser desclassificado. Atéapt-get --reinstall install pythonfalha porque o APT não fará o downgrade do Python para 2.7.5.Para reparar seu sistema, você precisa permitir que o APT realize downgrades. Para fazer isso, defina as preferências do APT . Crie um arquivo
/etc/apt/preferences.d/allow-downgradecontendoOs arquivos em
/etc/apt/preferences.d(mais/etc/apt/preferences) contêm declarações de prioridade que substituem a seleção padrão quando várias versões de um pacote estão disponíveis, que é "preferir a versão mais recente da distribuição de destino". Dar a um pacote uma prioridade acima de 1000 faz com que seja preferido mesmo que seja uma versão mais antiga que um pacote com uma prioridade mais baixa. Pacotes instalados têm prioridade 500, então o pacote do Ubuntu vence. Para mais informações, veja:Acho que depois de definir essas prioridades, você pode executar
fazer o downgrade de todos os seus pacotes para a versão no Ubuntu (os pacotes que não estiverem no Ubuntu não serão removidos). Execute também
apt-get -f installe não tente instalar nenhum outro software até que isso seja concluído com êxito.Quando tudo estiver desclassificado, remova o arquivo de preferências e execute
apt-get updatenovamente.fonte
man apt_preferences.Só há uma maneira de descobrir que estava funcionando.
Etapa 1: baixe o pacote python 2.7 deb daqui e instale-o
Use a ferramenta dbkg para listar tudo relacionado ao python
remova tudo o que foi encontrado acima
sudo dpkg --purge --force-all nome do pacote
tente fazer
isso lhe dará uma lista de pacotes no final corrompidos. Remova-os usando a etapa 3
Repita as etapas de 3 a 4 até o sudo apt upgrade não apresentar erros
Pode ser necessário criar um link simbólico para / usr / bin / python usando o local do python 2.7 que você instalou como pacote deb. (
locate bin/python) eln -s <path> /usr/bin/pythonNeste momento, o python deve ser corrigido. Mas faça-release-upgrade (leia o manual para saber como atualizar para o ubuntu mais recente, não o LTS)
