All in the the title
Anyone managed to install desktop version through d-i/preseed ?
Documentation seems to be inaccurate.
I show that they are building legacy alternate installer images (i.e., the previous ‘alternate’ server install ISO) here: http://cdimage.ubuntu.com/ubuntu-server/focal/daily/
These are daily images, though, and are not formally released images. I have not tried all of the possible methods of d-i based installation (e.g., have not tried d-i from a mini iso), but alternate-installer based processes that I used previously are not currently working with this 20.04 alternate installer. I’m getting failures at the network hardware detection step.
From prior conversations / threads on here, the Canonical developers say that they will spin-up / build the alternate installer images for 20.04, but will not support them. I don’t know if that means they won’t do any QA on them / if we’ll only get these daily builds and no formal releases … I’m not sure on that.
Non-daily debian-installer based images exist at http://cdimage.ubuntu.com/ubuntu-legacy-server/releases/20.04/release/.
