apt-get install失败

使用apt-get install安装meson失败，提示如下：

root@ubuntu:/home/run/code/drm# apt-get install meson
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?

解决方法：

root@ubuntu:/home/run/code/drm# rm /var/lib/dpkg/lock-frontend
root@ubuntu:/home/run/code/drm# rm /var/lib/dpkg/lock

重新安装meson：

root@ubuntu:/home/run/code/drm# apt-get install meson
