Ubuntu kinetic から noble へ

うっかりで kinetic のサーバをいくつか抱えていて、気付いた時に上げるようにしているんだけど毎度やり方を忘れるのでメモ

Modify your current /etc/apt/sources.list and replace the urls starting with http://archive... by http://old-releases

Once done, execute sudo apt update then sudo apt upgrade and sudo apt dist-upgrade

Then reboot

Modify the /etc/apt/sources.list and put back archive instead of old-releases

Modify the /etc/apt/sources.list and replace all occurences of kinetic by lunar

Then perform sudo apt update, sudo apt upgrade and sudo apt dist-upgrade. This will ensure that you upraded to 23.04

Then reboot

Then do a sudo do-release-upgrade to upgrade to 23.10

これで lunar にあげたら mantic に同様にあげて、やっと noble の世界にやってこれる
