apt-get upgrade pengecualian package tertentu

Pernah kepikiran nggak sobat, saat kita apt-get upgrade menambahkan pengecualian pada package tertentu ?
jadi misal gini nih :

root@zpanel:/home/rahox# apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages will be upgraded:
  base-files bind9 bind9-host bind9utils cpio dnsutils dpkg dpkg-dev git git-man grub-common grub-pc grub-pc-bin grub2-common
  isc-dhcp-client isc-dhcp-common krb5-locales libbind9-80 libc-bin libc-dev-bin libc6 libc6-dev libdns88 libdpkg-perl
  libfreetype6 libgcrypt11 libgd2-xpm libgnutls26 libgssapi-krb5-2 libisc84 libisccc80 libisccfg82 libk5crypto3 libkrb5-3

  libxml2 linux-libc-dev locales multiarch-support mysql-client-5.5 mysql-common mysql-server mysql-server-5.5
  mysql-server-core-5.5 openssh-client openssh-server openssl perl perl-base perl-modules ruby1.9.1 ruby1.9.1-dev sudo tzdata

Nah yang saya tandai warna merah itu kepengen dikecualikan atau pengen tidak ikut ter-upgrade saat melakukan apt-get upgrade.
Baiklah, caranya kita mark apt dulu package mana yang hendak kita hold atau kita kecualikan. Langsung aja ketik begini :

root@zpanel:/home/rahox# apt-mark hold openssh-client openssh-server
openssh-client set on hold.
openssh-server set on hold.

Nah abis itu dipastikan saat apt-get upgrade ngga ada lagi package openssh-server yang akan diupgrade. Hasilnya gini sob :

root@zpanel:/home/rahox# apt-get upgrade

Untuk menghapus mark tinggal unhold aja

root@zpanel:/home/rahox# apt-mark unhold openssh-client openssh-server
Canceled hold on openssh-client.
Canceled hold on openssh-server.

Semoga bermanfaat.
