I tried to update kernel, but I still have “Type: 2, File: /var/www/html/fog/lib/fog/fogftp.class.php, Line: 707, Message: ftp_put(): Could not create file., Host: 192.168.168.91, Username: fog”
The kernel update refers to FOS (the linux OS that is contained in bzImage and the inits), while in theory it could be this I don’t think its getting that far the issue still appears to be in iPXE side or the firmware on the device. I think @Sebastian-Roth had a custom ipxe.efi that sent out debug messages he was testing with another fog admin. Maybe when he has time he can add his wisdom to this thread.
This issue has nothing to do with the host OS (99% sure) or FOS (51% sure) but we should focus on iPXE or target hardware firmware. I do have another solution where we have use usb booting into FOS if everything else fails. I would really like us to understand why its failing and get it resolved. I think others will have the same issue as you in the future.
