Ubuntu系统apt问题

使用apt安装时报错：

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?

解决方案：

方案一：

sudo killall apt apt-get

如果提示没有apt进程：

apt: no process found
apt-get: no process found

往下看方案二

方案二：

依次执行：

sudo rm /var/lib/apt/lists/lock
sudo rm /var/cache/apt/archives/lock
sudo rm /var/lib/dpkg/lock*
sudo dpkg --configure -a
sudo apt update
