Azure Virtual Machines

Upgrade Linux Ubuntu VM to 22.04 and 24.04

My steps:

• sudo apt update
• sudo apt upgrade
• reboot
• shutdown VM
• create a snapshot of OS disk
• boot VM
• UPGRADE steps:
  • sudo do-release-upgrade
  • at the beginning of the process, a new sshd will be started. Take note of the port (i.e. 1022).
  • could appear messages of locally modified configration file like ‘a new version (/usr/share/chrony/chrony.conf) of configuration file /etc/chrony/chrony.conf is available, but the version installed currently has been locally modified’. Often the best option is keep the local version currently installed. Or ‘Configuration file ‘/etc/default/useradd’ –> keep your currently-installed version
  • at the end, reboot the VM
• delete os disk snapshot if everthing works fine

Good luck!
