Problems installing Ubuntu 18.04 LTS in KVM

[gkovacs]

I have tried to install Ubuntu 18.04 LTS Server in a KVM machine on a recently updated Proxmox 5.4 host, but after entering the IPv4 address manually, and hitting "Save" the installer instantly restarts. Tried different hardware configurations (E1000 vs. VirtIO-net, disconnecting the adapter, etc.), but it happens every time, and can't skip it as Ubuntu requires one working network connection.

Ubuntu 16.04 LTS and Debian 9 installed without any problems in the same KVM guest.

Has anyone seen similar problems?

hi.

i don't know why your problem occurs, but have you tried the minimal version?
maybe you don't have enough resources allocated on your vm?
