Minha configuração é a seguinte: meu usuário está logado através de uma autenticação de rede, sua casa é montada em NFS (tudo isso no Ubuntu 16.04).
Estou tentando configurar minha máquina para executar vários aptcomandos como updateou install:
updatefalha comE: Unable to change to /home/$user/ - chdir (13: Permission denied). Eu consegui consertar isso rapidamente comesta resposta, basicamentecd /installme avisa que:dpkg: warning: failed to open configuration file '/home/zr258722/.dpkg.cfg' for reading: Permission denied.
Como devo me livrar desses erros/avisos?

Sua pasta pessoal deve ter pelo menos as seguintes permissões: u=rwx,g=r,o=r, executechmod 0711 /home/$user
Responder2
Normalmente root não tem permissões para acessar montagens NFS, a menos que no_root_squash esteja definido para a exportação, o apt-get é executado no contexto root com sudo e não pode acessar o diretório inicial. Este é um aviso irritante, mas inofensivo, que pode ser ignorado.
Responder3
Às vezes, a instalação acontece de tal forma que parece que não é o usuário, mas o programa que está pedindo permissão. Você pode tentar alterar as permissões da pasta ofensiva para
chmod 777 offending_foldername
isso permitiria que todos os usuários lessem, escrevessem e executassem. Se isso resolver o problema, você provavelmente poderá se aprofundar e corrigir o problema por motivos de segurança de rede.
