yes, I do not see any problem with Ubuntu 20.04.

check your Proxmox VE updates and your VM settings.

Same issue here. All updates for Proxmox VE are installed. The VM settings were left at standard.
Anyone any ideas?
Best regards,
Johe

Please post your:

> pveversion -v

and

> qm config VMID

As it works perfectly here our testlabs, we need to find out what is different on your side. And which hardware do you have in full detail?

ubuntu live server iso needs at least 1 gb ram (see https://ubuntu.com/server/docs/installation)

Yeah that's it. Found some other forum posts with others complaining about the memory usage. You can still download the legacy installers at http://cdimage.ubuntu.com/ubuntu-legacy-server/releases/20.04/release/ which don't run the live image.
