我在Linux mogodb上安装了它，并且可以正常工作，但是大约8个月后，我不记得发生了什么，因此我卸载并重新安装了它，然后它可以正常工作。现在，当我卸载并重新安装它时，它不起作用。我的命令行来卸载它并喜欢
sudo service mongod stop
sudo apt-get purge mongodb-org *
sudo rm -r / var / log / mongodb
sudo rm -r / var / lib / mongodb.
我按照以下网址进行安装； https://www.tutorialspoint.com/mongodb/mongodb_quick_guide.htm
我的错误是当我放入“ sudo apt-get update”时，它看起来像这样
