Hello,
I just wanted to share my experience with upgrading from 5 to 7 successfully on an odroid HC2.
Before updating make a backup. If you are running OMV from an sd card, you can easily backup the whole card with openmediavault-backup plugin and run a dd full disk. It is really easy to restore by running something like gunzip backup-omv-yyyy-mm-dd-hh-mm-ss.ddfull.gz | dd of=/dev/sdX bs=1M status=progress where sdX is your sd card (on a different computer with a card reader)
First problem: omv-release-upgrade -> command does not exists.
Second problem: The repository 'http://apt.armbian.com buster Release' no longer has a Release file.
The first problem happened because OMV5 was not updated to its latest version. Running omv-upgrade should have fixed it but since the buster apt repo is now gone, running omv-upgrade and then omv-release-upgrade broke my system. I restored from backup and changed the armbian mirror to https://imola.armbian.com/apt/. After that the upgrade went flawlessly.
Step by step of what i did:
- Make a backup and save it somewhere you can access without omv
- Open the file /etc/apt/sources.list.d/armbian.list and change http://apt.armbian.com to https://imola.armbian.com/apt
- Run omv-upgrade (now the command for omv-release-upgrade should be available)
- Run omv-release-upgrade.
- Reboot
Now OMV was upgraded to OMV6 without issues. Verify that everything is working correctly
- Make another backup on OMV6 and store it somewhere you can access without omv
- Open the file /etc/apt/sources.list.d/armbian.list and restore http://apt.armbian.com
- Run omv-release-upgrade.
Now OMV7 is installed correctly and everything runs perfectly.
Thank you to the OMV team for their great work.
