我在Debian10安装Mariadb时遇到一个错误
$ apt install mariadb-server
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?
造成这个错误的原因有以下几种可能
- 软件更新程序正在运行
- apt程序正在运行
apt为了防止冲突，在运行期间会生成相关的lock文件，当其他人在这期间运行apt命令时会检测到lock文件是否存在从而保证同一时间只能运行一个apt程序。这个设计理论上是完美的，但也会有意外，比如在apt某次运行时意外退出没有来得及清理lock文件，那么这就造成系统误判。
所以要么等待以上两种情况处理完成，如果你确定它没有在Terminal里运行的话，可以通过以下方式重置一下
如果你有killall命令，执行一下
killall apt apt-get
如果仍然不能工作，就只能强制删除lock文件
rm /var/lib/apt/lists/lock
rm /var/cache/apt/archives/lock
rm /var/lib/dpkg/lock*
然后需要重新配置一下软件包
dpkg --configure -a
然后再进行update
apt update
假如成功的话，就可以继续安装MariaDB了
$ apt install mariadb-server
