ubuntu에러(Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)

가끔 $sudo apt-get update를 할 때

아래 메시지가 발생할 때가 있다. (우분투 14.04기준)

Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)

간단하다.

$sudo rm /var/lib/apt/lists/* -vf

$sudo apt-get update

끝
