리눅스 | yum 에러 해결 Another app is currently holding the yum lock

yum을 사용하다보면 Another app is currently holding the yum lock 라는 에러가 뜰 때가 있다.

yum이 실행중인 상태로 멈춰있어서 새로운 yum 명령어를 쓸 수 없을 때 발생한다.

 

이런 경우 PID 넘버를 확인해서 프로세스는 죽이던지, yum.pid의 존재 유무를 확인 후 삭제해주면 된다.

[root@server ~]# yum info Mariadb-server
Loaded plugins: fastestmirror, langpacks
Existing lock /var/run/yum.pid: another copy is running as pid 2907.
Another app is currently holding the yum lock; waiting for it to exit...
  The other application is: PackageKit

    State  : Sleeping, pid: 2907

리눅스가 알려주는대로 pid 2907을 죽이던지, ps -ef | grep yum 명령어를 통해 PID 번호를 알아낼 수 있다.

그 후 kill -9 명령어를 사용해서 죽이고 재실행하기.

[root@server ~]# ps -ef | grep yum
root       2907   1987  4 18:34 ?        00:00:17 /usr/bin/python /usr/share/PackageKit/helpers/yum/yumBackend.py get-updates none
root       4438   2830  0 18:40 pts/0    00:00:00 grep --color=auto yum
[root@server ~]# kill -9 2907
[root@server ~]# yum info MariaDB-server
