前言

在日常区块链或是正常的使用中,总是会遇到这个问题

Waiting for cache lock: Could not get lock /var/lib/dpkg/lock-frontend. It is heWaiting for cache lock: Could not get lock /var/lib/dpkg/lock-frontend. It is heWaiting for cache lock: Could not get lock /var/lib/dpkg/lock-frontend. It is heWaiting for cache lock: Could not get lock /var/lib/dpkg/lock-frontend. It is he^C by process 39627 (unattended-upgr)... 3s

那么这个事情该怎么办呢?

方法一:

一般我们可以选择重启一下电脑,这个一般都可以解决

但是如果有人和我一样重启了电脑还是报这个错误的话

方法二:

我们可以去查看一下网络,是不是网卡的问题,首先ping www.baidu.com如果链路没问题可以走的通的话,那么久可以重启一下网卡使用命令 sudo systemctl restart net-tools,有些人可能会没net-tools这个工具,那么我们就去查看虚拟机的右上角是否有这个符号的存在

这也代表着我们的虚拟机现在的网络是正常的,那么就去使用ip a,查看我们目前有没有分配虚拟ip,如果有着这个ip的话我们就去看我们的虚拟网络编辑器中的ip 是否与我们的ip 一致

虚拟网络编辑器在哪里呢?

 在左上角的编辑中点开虚拟网络编辑器,查看两个东西一个是是否有着V0网络,第二个是否与我们分配的ip一致,不一致的话大家就点开更改设置将我们的模式设置成NAT就可以了 

 还有一种比较特殊的情况就是虚拟机网关问题,这个比较复杂要修改配置文件,如果有朋友遇到的话留言给我就可以了我会教你怎么解决,那么遇到这个问题怎么判断是不是这个问题呢?

这个就在你的Windows系统上点击Windows+R输入cmd,在弹出黑框之后输入ipconfig,查看Windows中的网卡ip是否与网络编辑器中的一致(看前三个小数点的数字是否一致),如果不一致的话就将自己的网络编辑器设置为桥接试一下,在解决不了就留言在这里。

这个问题到这里就解决完成啦
