Recentemente, tentei resolver um problema relacionado a uma incompatibilidade na versão do meu java jre e do compilador java, então tentei algo sugerido nessa resposta, que parecia ser relativamente inofensiva, com muitos votos positivos e foi a resposta selecionada para a pergunta certa: link
no entanto, infelizmente eu não usei o meu cérebro antes de executar o seguinte comando, que seria o comando sugerido no meu caso:
sudo ln -s -f /usr/bin/* /usr/bin
Depois de pensar um pouco mais, percebo que isso está ligando simbolicamente todos os arquivos no diretório / usr / bin de volta ao diretório pai, criando assim uma estrutura de arquivos cíclica que continua em adfinitum. Então, um pesadelo.
quando tento ls -l no meu diretório / usr / bin, recebo várias entradas semelhantes:
-rwxr-xr-r 1 root root 5518 Feb 12 2014 xzcat -> /usr/bin/xzcat
Mas é claro que existe uma maneira simples de desfazer isso? O problema é que não tenho certeza sobre quais arquivos eu posso excluir, uma vez que nenhum arquivo foi realmente incluído nesse processo.
Alguma opinião?
Aqui está a saída do meu comando:

EDIT: seguindo o conselho do @Stephen Kitt, estou tentando usar o debsums para resolver esse problema. Demorou algum trabalho para obter o pacote debsums para baixar corretamente, dado que muitos programas estão quebrados, mas eu finalmente consegui executar debsums -c . Esta é a saída:
sh: 1: awk: Too many levels of symbolic links
sh: 1: awk: Too many levels of symbolic links
sh: 1: awk: Too many levels of symbolic links
sh: 1: awk: Too many levels of symbolic links
sh: 1: awk: Too many levels of symbolic links
sh: 1: awk: Too many levels of symbolic links
sh: 1: awk: Too many levels of symbolic links
sh: 1: awk: Too many levels of symbolic links
Portanto, parece que o debsums não está sendo instalado corretamente.
EDIT: depois de corrigir awk , consegui executar o debsums e agora estou obtendo a seguinte saída:
/boot/vmlinuz-4.2.0-16-generic
/usr/lib/python3/dist-packages/cupshelpers/__pycache__/__init__.cpython-34.pyc
/usr/lib/python3/dist-packages/cupshelpers/__pycache__/config.cpython-34.pyc

/usr/lib/python3/dist-packages/cupshelpers/__pycache__/ppds.cpython-34.pyc
/usr/lib/python3/dist-packages/cupshelpers/__pycache__/xmldriverprefs.cpython-34.pyc
Embora isso seja encorajador, estou um pouco preocupado com a falta de muitas mudanças. Considerando todos os links simbólicos que foram excluídos (> 100) de muitas partes diferentes do meu diretório /usr/bin , é um pouco estranho que todas as alterações estejam na minha biblioteca python. Isso não parece muito improvável ou a debsums está funcionando corretamente?
OK supondo que tudo que eu preciso fazer é substituir a instalação do python3, como faço isso? Eu ainda não entendo como usar o dpkg para baixar este arquivo. Quando eu procuro usando dpkg -S python3 , eu obtenho os nomes dos pacotes, não os arquivos .deb. mas simplesmente pesquisando e baixando o arquivo .deb relevante não coloca o arquivo no local certo. Eu sei que isso parece uma pergunta simples para alguns, mas eu ainda não sei como fazer essa coisa básica que me permitirá resolver o problema.
