Failed upgrade attempt OMV 4 to 5

Hi All,

I hadn't realized that OMV 6 is fully released and figured I need to upgrade to keep up with the supported versions. I attempted to upgrade from OMV 4 to 5 and the upgrade failed. It looks like it's something to do with unionFS. I've attached the upgrade script output in a text file to this post. Would you be able to point out where I'm going wrong? Thanks in advance.

Thanks for the help, I was able to run your script and successfully upgraded to 5.6.26. I then rebooted and started to run the other commands that were displayed at the bottom of the script and I'm unable to resolve github.com. I did reboot after running apt-get purge openmediavault-omvextrasorg resolvconf" because it the system recommended it. Here is what I get:

root@OMV:~# apt-get purge openmediavault-omvextrasorg resolvconf

I did some searching and it looks like the resolv.d service wasn't running. I found this post resolv.conf missing and it seems to have fixed the DNS resolution issue even after reboot.

Thanks for the assistance. I did run into another issue where the docker daemon didn't start automatically after the upgrade but was able to enable them with systemctl. I was able to finalize the upgrade and everything is working as expected.
