apt-get dpkg lock 和 debconf 問題

 

一：

在用sudo apt-get install 安裝軟件時，由於速度太慢，想換個軟件源，直接關閉了終端，apt－get但進程沒有結束，結果終端提示

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?

E: 無法獲得鎖 /var/lib/dpkg/lock – open (11: 資源暫時不可用)
E: 無法鎖定管理目錄(/var/lib/dpkg/)，是否有其他進程正占用它？

 

解決辦法如下：
1 終端輸入 ps -aux | grep apt，列出進程。找到含有apt的進程，直接sudo kill PID。解決。
2 強制解鎖,命令

sudo rm /var/cache/apt/archives/lock
sudo rm /var/lib/dpkg/lock

 

 

二：

debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: Resource temporarily unavailable

debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: 資源暫時不可用

 

Setting up shim-signed (1.19~16.04.1+0.8-0ubuntu2) ...
debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: Resource temporarily unavailable
dpkg: error processing package shim-signed (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 shim-signed

 

解決方法：

$ sudo lsof /var/cache/debconf/config.dat
lsof: WARNING: can't stat() fuse.gvfs-fuse-daemon file system /home/amw/.gvfs
      Output information may be incomplete.
COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
frontend 3350 root    4uW  REG    7,0    40347 2966 /var/cache/debconf/config.dat

$ sudo kill 3350

$ sudo apt-get autoclean

$ sudo apt-get clean

$ sudo apt-get autoremove 

$ sudo apt-get update

 

然后可以試着用apt-get安裝軟件。
