L’heure est venue de mettre notre serveur Apollo à jour: jusqu’alors sous Ubuntu 22.04 (jammy jellyfish), nous passons à Ubuntu 24.04 LTS (noble numbat).
On installe l’outil de mise à jour Ubuntu:
apt install ubuntu-release-upgrader-coreOn vérifie que l’outil est bien configuré pour récupérer la version LTS:
grep 'lts' /etc/update-manager/release-upgrades
# lts - Check to see if a new LTS release is available. The upgrader
Prompt=ltsCode language: PHP (php)On ajoute une règle pour ufw pour ouvrir le port 1022 en cas de souci:
sudo ufw allow 1022/tcp comment 'Open port ssh TCP/1022 as failsafe for upgrades'
Rule added
Rule added (v6)Code language: JavaScript (javascript)On lance la mise à jour:

Continue running under SSH?
This session appears to be running under ssh. It is not recommended
to perform a upgrade over ssh currently because in case of failure it
is harder to recover.
If you continue, an additional ssh daemon will be started at port
'1022'.
Do you want to continue?
Continue [yN] y
Starting additional sshd
To make recovery in case of failure easier, an additional sshd will
be started on port '1022'. If anything goes wrong with the running
ssh you can still connect to the additional one.
If you run a firewall, you may need to temporarily open this port. As
this is potentially dangerous it's not done automatically. You can
open the port with e.g.:
'iptables -I INPUT -p tcp --dport 1022 -j ACCEPT'

Codename: nobleCode language: CSS (css)Il ne reste plus qu’à réactiver les repo apt qui ont été désactivés pendant la mise à jour:
add-apt-repository ppa:ondrej/php
add-apt-repository ppa:ondrej/nginx-mainline
add-apt-repository ppa:ubuntuhandbook1/transmissionEnsuite, il faut faire le ménage dans le répertoire /etc/apt/sources.list.d :
ls -lash /etc/apt/sources.list.dCode language: PHP (php)et changer les occurences “jammy” en “noble”.
Enfin, il nous faut reconfigurer les paquets qui peuvent avoir été désinstallés:
# MySQL
dpkg-reconfigure mysql-apt-config
# Python deps
apt install pipx
sudo rm /usr/local/bin/flexget /usr/local/bin/flexget-headless
pipx install flexget subliminal
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc
pipx inject flexget subliminalCode language: PHP (php)Il vous suffit ensuite de lancer les mises à jour pour retrouver des paquets mis à jour pour noble numbat:
apt update && apt upgradeBonne migration !
