W: There is no public key available for the following key IDs:
8B48AD6246925553

untuk mengatasinya, bisa dengan dua cara berikut ini

gpg --keyserver pgp.mit.edu --recv-keys 8B48AD6246925553

output hasil eksekusi perintah diatas

gpg: requesting key 46925553 from hkp server pgp.mit.edu
gpg: /root/.gnupg/trustdb.gpg: trustdb created
gpg: key 46925553: public key "Debian Archive Automatic Signing Key (7.0/wheezy) <[email protected]>" imported
gpg: no ultimately trusted keys found
gpg: Total number processed: 1
gpg:               imported: 1  (RSA: 1)

dan yang kedua adalah dengan cara menginstall aplikasi debian-keyring debian-archive-keyring

apt-get install debian-keyring debian-archive-keyring

selamat, masalahnya sudah teratasi.
