0 GPG error di Ubuntu 9.10 Karmic Koala

Jika kita ingin melakukan update manager pada komputer yang ber-OS ubuntu, seringkali terjadi error di bagian GPG-nya. Sebagai contoh ketika kita melakukan update "System > Administration > Update Manager", kemudian muncul warning seperti dibawah :

W: GPG error: http://ppa.launchpad.net karmic Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 5A9BF3BB4E5E17B6

Jika mengalami masalah seperti ini jangan langsung panik, karena ada solusinya ^_^, silahkan buka terminal kemudian ketik sintac di bawah ini

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 5A9BF3BB4E5E17B6

Jangan lupa deretan huruf hexa pada bagian paling akhir sintac diatas, harus ditulis sama dengan deretan huruf hexa yang muncul pada tampilan error. Misalkan kalau di komputer saya (meskipun dummy) tertulis 5A9BF3BB4E5E17B6.

Setelah melakukan perintah diatas, maka kemudian di tampilan terminal kita akan muncul kurang lebih seperti ini :

Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /etc/apt/secring.gpg --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --keyserver keyserver.ubuntu.com --recv-keys 5A9BF3BB4E5E17B6

gpg: requesting key 4E5E17B6 from hkp server keyserver.ubuntu.com

gpg: key 4E5E17B6: public key "Launchpad PPA for chromium-daily" imported

gpg: no ultimately trusted keys found

gpg: Total number processed: 1

gpg: imported: 1 (RSA: 1)

Kemudian barulah kita bisa update lagi dengan mengetikkan sudo apt-get update (ini bagi yang belum masuk root) atau langsung saja apt-get update (bagi yang sudah masuk ke root)

root@alfaruqi-laptop:/etc/apt# apt-get update
