数字海洋 - 18.04 Ubuntu 服务器设置错误

Digital Ocean - 18.04 Ubuntu Server Setup ERROR

我正在遵循此指南:https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-18-04

我参与了 运行

 sudo apt install python3-pip python3-dev libpq-dev postgresql postgresql-contrib nginx curl

它让我说是或否

当服务器将我踢出时,我让终端保持打开状态。

但是当我重新登录时,它不允许我运行使用相同的代码来完成所有安装,并出现以下错误消息:

  E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable)
  E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

要了解活动进程(1.process 名称 2. 进程 ID),我必须 运行:

 ps aux | grep -i apt

比删除进程

 sudo kill -9 THAT_SPECIFIC_PROCESS_ID_COMES_HERE

比重新运行安装代码

 sudo apt install python3-pip python3-dev libpq-dev postgresql postgresql-contrib nginx curl
