Ubuntu Release Cycle & Support

https://wiki.ubuntu.com/Releases <<<<

https://changelogs.ubuntu.com/meta-release-lts

When a new LTS is available (all 2 years in "even" years - so 2026.04 and 2028.4 - LTS might show up with the first path in august ... e.g. 26.04.1 LTS), you can update as follows on the console via "noVNC":

do-release-upgrade

(console is running with an EN keyboard only and copy&paste seems not to work ...)

You can find the current version as follows:

view /etc/os-release

hostnamectl

lsb_release -a

cat /etc/issue

view /etc/lsb-release

cat /etc/timezone

Change Timezone to CET

vi /etc/hostname
=> Reboot

Set: (seems not persistent ...)
hostname host.domain.de

Start Issues Service "systemd-networkd-wait-online.service"

https://askubuntu.com/questions/1217252/boot-process-hangs-at-systemd-networkd-wait-online

systemctl disable systemd-networkd.service
systemctl disable systemd-networkd.socket
systemctl disable systemd-networkd-wait-online.service

systemctl starts systemd-networkd.service
systemctl start systemd-networkd.socket
systemctl start systemd-networkd-wait-online.service

systemctl status systemd-networkd.service
systemctl status systemd-networkd.socket
systemctl status systemd-networkd-wait-online.service

... this seems not to work for the next boot ... why? is there some presets by the hoster?
