I'm new to LAVA and I have some issue with 'iso-installer' for ubuntu 20.04
. As you know, in ubuntu 20.04 the preseed file would not use
'debian_installer' and use 'subiquity' instead, Also LAVA does not support
'subiquity' for 'iso-installer', so I don't know how can I use
'iso-installer' for testing my ubuntu 20.04.
