Could not get lock /var/lib/dpkg/lock

Instal ubuntu restricted extras yang terputus gara-gara koneksi inet putus akhirnya muncul

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?

habis googling dapat tutorial berikut ini. Sudah dicoba dan berhasil (alhamdulillah..)

***
Jika setelah install ulang Ubuntu, maka yang pasti kalian akan install jdk. Apabila terdapat pesan error kayak gini  :

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?

Maka solusinya  :

- buka terminal, lalu ketikan
$ sudo rm /var/lib/dpkg/lock
bisa juga dengan perintah
$ killall aptitude && killall apt-get atau killall dpkg && killall frontend

- Setelah berhasil, lalu ketikan perintah  :

# dpkg --configure -a

Jika pesan error nya kayak gini :

E: Could not get lock /var/cache/apt/archives/lock - open (11 Resource temporarily unavailable)

E: Unable to lock the download directory
Solusinya  :
$ sudo rm /var/cache/apt/archives/lock
