最近Ubuntu更新比较频繁（实际上一直都更新频繁，你就当更新及时吧 )，总有那么一两次更新老半天还没完成。最近更新问题就比较多，比如更新flash控件就会一直停在那里，无法完成也无法取消。再比如下载30多M的内核，居然也会下载失败，或此时咱要安装个啥软件会等不了那么久，咱就会强制结束。

强制结束后问题就来了，无法再次更新，在终端使用apt-get update或upgrade会提示is locked：

1
2
3
xxx@expired:~$ sudo apt-get upgrade
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

解决方法便是：

1.删除lock

1
sudo rm  /var/lib/dpkg/lock

2.更新软件库设置

1
sudo dpkg --configure -a

完成后就继续更新吧。前面说的flash无法通过Ubuntu的更新管理或apt-get更新问题，还是自己到adobe网站下载so文件，然后手动替换吧，方法可以参考：Ubuntu安装flash控件，新版本的flash已经把32位和64位版本合在一起了，所以下载会得到install_flash_player_11_Linux_x86_64.tar.gz，本次更新还涉及到其他一些文件，可以看压缩包里的readme.txt.
