Could not get lock /var/lib/dpkg/lock-frontend解決

 

在安裝軟件包時如果出現Could not get lock /var/lib/dpkg/lock-frontend，說明之前使用apt時出現異常，沒有正常關閉，還在運行。

lgj@lgj-Lenovo-G470:~$ sudo apt-get install alien
[sudo] password for lgj: 
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?

解決，使用ps 和 grep查找apt的pid,並使用kill殺死掉。

lgj@lgj-Lenovo-G470:~$  ps afx|grep apt
16214 ?        S      0:00  \_ sudo apt install rpm
16215 ?        S      0:01  |   \_ apt install rpm
16721 pts/3    S+     0:00          \_ grep --color=auto apt
lgj@lgj-Lenovo-G470:~$ kill 16214
bash: kill: (16214) - Operation not permitted
lgj@lgj-Lenovo-G470:~$ sudo kill 16214
lgj@lgj-Lenovo-G470:~$ sudo kill 16215

執行安裝指令

lgj@lgj-Lenovo-G470:~$ sudo apt-get install alien
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?

 

  如果仍然出現，需要手動刪除 /var/lib/dpkg/lock即可。

lgj@lgj-Lenovo-G470:~$ rm -rf /var/lib/dpkg/lock
