Ended up doing Windows server 2012R2 bare metal and updated through .exe's. Thanks for all the help!
Currently trying to update my bios from 1.4 to 2.11 however I cant seem to do so successfully. When booting into the Linux recovery with SUU it errors out with a memory error, so i tried through the lifecycle and cant use ftp.dell.com anymore and the new downloads.dell.com also doesn't work with http? my server is currently running Proxmox. is there any other way to update?
