Had anyone same problem with installation in Proxmox Virtual Environment an UCS server?
Other linux like imges works great - there is a problem only with UCS iso DVD.
I didn’t have any issue when I loaded UCS in proxmox, but I don’t recall which version I started with. I still have the file, UCS-Installation-amd64.iso on my drive. It’s from 2019-09-05 if that helps. If you can find an older image and then upgrade from there it might work.
I installed 4.4-4 on 2 different PVE Servers last week without any problem - for me it looks like your ucs-iso image upload is defektive - check the iso
