Acabei de instalar o Ubuntu. Meu problema é que eu estou tentando gravar um arquivo de log para casa. Eu estou usando logcat de um módulo python chamado adb . Quando eu tento o comando de terminal adb logcat -f <path> eu deveria ser capaz de produzir este log para um arquivo de texto no meu disco rígido, mas em vez disso eu recebo o erro:
couldn't open output file: Read-only file system
Isso ocorre apesar de tentar o comando sudo adb logcat -f <path> .
Para <path> eu tenho tentado apenas 'log' e 'log.txt'
Eu posso gravar arquivos no disco usando cat > e posso salvar arquivos sem problemas. Eu li que isso pode ser causado por um disco rígido com falha, mas até agora não vi nenhuma outra evidência disso. Qualquer ajuda para entender por que isso está acontecendo e como superá-lo seria muito apreciada. Caso alguém esteja se perguntando, é necessário para eu enviar este arquivo para o disco.
EDITAR:
Devo mencionar que de fato tive um problema com minha partição de swap. Eu estava recebendo um erro na melodia de /dev/mapper/cryptswap1 is not ready yet or not present (não na forma exata) na tela inicial durante a inicialização, mas eu reformatei e fiz uma nova partição de troca que eliminou o erro. No entanto, ambos antes de ver o problema, e ainda agora, o gparted rotula a partição swap como 'desconhecida'. free -m não mostra problemas, nem swapon -s

Como solução alternativa, você pode simplesmente redirecionar a saída você mesmo, em vez de usar a opção -f :
adb logcat > log
Eu estou supondo que o programa pode mudar seu diretório de trabalho, então ele está tentando criar log em algum lugar onde você não tem acesso de gravação. Em caso afirmativo, você também deve conseguir que ele funcione usando um caminho absoluto:
adb logcat > /home/username/log
