[ubuntu] Could not get lock /var/lib/dpkg/lock ... 오류

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?

 

apt-get 관련 기능을 사용할 때 위와 같은 오류가 표시된다.

그럴떈 아래와 같이 해결하자.

$ sudo killall apt apt-get
$ sudo rm /var/lib/apt/lists/lock
$ sudo rm /var/cache/apt/archives/lock
$ sudo rm /var/lib/dpkg/lock*
$ sudo dpkg --configure -a 
$ sudo apt update
