Download Ubuntu Minimal ISO 20.04LTS?
Solution 1:
It has moved to a new location: http://archive.ubuntu.com/ubuntu/dists/focal/main/installer-amd64/current/legacy-images/netboot/mini.iso
Note that it moved to legacy images. Folks who use this image should start to look at newer options:
- dd-able .img images
- Cloud images
- Ubuntu Base
- Ubuntu Core
- Netboot-using-PXE
...and others.
