1 Ubuntu 및 > 버젂업그레이드가이드 개요 - 이문서는업그레이드권고문서가아닌가이드문서임을알려드립니다. Olleh Ucloud biz 에서맊들어진 Ubuntu 10.04(lucid), Ubuntu 11.04(natty) VM 을 Ubuntu 12.04(precise) 로버전업그레이드위한 User 가이드입니다. 여기서말하는버전 (release) 업그레이드란 Ubuntu 10.XX 에서 Ubuntu 11.XX 로의업그 레이드, Ubuntu 11.XX 에서 Ubuntu 12.XX 로의업그레이드를말합니다. Ubuntu 에서버전업그레이드방법 위링크에서확인가능하며, 상세설명에대해서는위링크를참조바랍니다. 또한이문서에서설명하는 통상버전업그레이드는 do-release-upgrade command를통해가능하며, do-releaseupgrade 을실행하면 kernel 또한업그레이드되며, do-release-upgrade 명령을통해버전업그레이드가아닌 apt-get install 을통해 Kernel 맊을 upgrade 실행시에도아래적용방법섹션의 grub 패키지설치및 /etc/fstab 을수정 부문을반드시참조하시기바랍니다. 버젂업그레이드는많은패키지들이자동업그레이드되므로, 버젂업그레이드는 Olleh Ucloud biz에서권고하는필수사항이아니며, 버젂업그레이드의실행유무는사용하시는고객님의선택이며, 버젂업그레이드로인한고객님의 Application 에대한이상유무에대한지원이불가함을미리알려드립니다.

2 적용방법 ubuntu 버젂체크 - 현재의 release 버전과 kernel 버전을확인합니다. - lsb_relase a command 를통해현재 release 버전을아래와같이확인가능하며, 확인된 release 버전에따라업그레이드과정이상이합니다. < release 버전확인 ~# lsb_release a No LSB modules are available. Distributor ID: Description: Ubuntu Ubuntu LTS Release: Codename: lucid < kernel 버전확인 ~# uname -a Linux ubuntupgrade virtual #57~lucid1-Ubuntu SMP Tue Mar 6 20:40:43 UTC 2012 x86_64 GNU/Linux 이제위에서확인된 release 에따라아래의두가지섹션중선택하시어진행하시면됩니다. 적용방법 1. release 를 release 로버젂업그레이드 적용방법 2. release 를 release 로버젂업그레이드 2/16

3 1. release 를 release 로버젂업그레이드 - 실행하기전에업그레이드이후빈번히발생되는문제를예방하기위해 grub 패키지설치및 /etc/fstab 을수정합니다. - 원할한패키지업그레이드를위해 apt repository source list 를아래와같이수정이필요합니다.
