Web GUI is displaying several things incorrectly

[Tim Reynolds]

I had an old fog server running Ubuntu 18.04 with Fog 1.5.9. I am migrating to a new fog server Hyper-V VM on a Windows 2022 server. The Hyper-V VM is a Gen 2 running Ubuntu 22.04.2 LTS with Fog 1.5.10. I followed online documentation regarding migrating from one server to another. The OS install on the new VM went fine as well as the Ubuntu install. The Fog SQL DB migrated over as well as all of the image files. I followed the steps to copy the SSL folder from one server to the other so that the snapins and current Fog client control would still function. I can access the web GUI and can see all of my images and hosts. The problem is that when I list all hosts everything looks correct but when click on a host the page displays in a sort of “text” looking layout. I have attached an image of what it looks like.
Everything else seems to work as it is supposed to.
When I list all images, I can click on any image definition and the subsequent page renders correctly. The only other thing I can find is regarding Snapins. When I click on the “Snapins” icon the correct page shows. I can click on New Snapin and it will allow me to create the snapin, but if I select “List all snapins” it shows me a “This page isn’t working” message with HTTP error 500. Obviously, I have done something correctly.
Hopefully, I have given you enough info to point me in the right direction to resolve.
Thanks in advance!

Here is a portion of the apache2.log file showing the results of loading the Hosts Details page:

Since this was a migration from an old server to a new and Fog V1.5.9 to Fog 1.5.10 I followed the instructions located here - https://wiki.fogproject.org/wiki/index.php?title=Migrate_FOG and then completed the steps in the “If old server was FOG 1.3.0+” section.

@Tim-Reynolds On first sight this looks a lot like a PHP 8 issue. Are you absolutely sure you installed FOG 1.5.10? Not 1.5.9?

[Tim Reynolds]

@Sebastian-Roth I am sure. When I go to the management console page, I see this login page:

When I go the Fog Version Information page, I see the following:

The Fog I upgraded from was 1.5.9. But all I did was copy the images and SSL info as directed in the Fog migrations instructions.
Most everything works. I even dropped an image from the new server. The main (very important) things that don’t work is the Hosts Details page and the Snapins page.
I’m thinking I might try using Clonezilla to clone the current server and then restore that image into a new VM then upgrade from the VM. I’ve never done something like that. Any thoughts on that?
Thanks in advance!

@Tim-Reynolds @Sebastian-Roth Any other ideas? My backup plan is to use Clonezilla to clone the physical fog server into a Hyper-V VM, but I’m not having a lot of luck with that either. What are your thoughts about installing Fog 1.5.9 instead of 1.5.10 onto my Hyper-V VM and then migrating the images, SQL DB, and SSL from the old server which was 1.5.9? Then, if everything works, I could upgrade the installation in place.
Thanks!

@Tim-Reynolds @Sebastian-Roth I resolved the issue. I created a new VM with the same Ubuntu 22.04 then installed the latest dev branch of Fog (1.5.10.5) instead of the stable version. After importing images and the SSL folder and re-installing, everything now works as it should.

@Tim-Reynolds Thanks for the update and great you got this fixed.
