Ubuntu错误：E: Could not open lock file /var/lib/dpkg/lock-frontend

Ubuntu错误：E: Could not open lock file /var/lib/dpkg/lock-frontend

---

1、第一种

ubuntu使用apt下载和更新软件的时候，出现了以下错误：

E: Could not open lock file /var/lib/dpkg/lock-frontend - open (2: No such file or directory)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?

尝试解决办法1：消息已经提示了，are you root ?，所以可以尝试将命令加sudo。

尝试解决办法2：依次输入以下命令

sudo mkdir -p /var/lib/dpkg/{alternatives,info,parts,triggers,updates}
sudo cp /var/backups/dpkg.status.0 /var/lib/dpkg/status
sudo apt-get download dpkg
sudo dpkg -i dpkg*.deb
sudo apt-get download base-files
sudo dpkg -i base-files*.deb
sudo apt-get update
sudo apt-get check

2、第二种

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?

执行：

sudo rm /var/lib/dpkg/lock-frontend
sudo rm /var/lib/dpkg/lock

重新apt-get即可！
