I think this might be what I need to think about
Tried command
swupd os-install /mnt --bundles=os-core,os-core-update,kernel-native --statedir=/mnt/var/lib/swupd
root@clr-live /home/clrlinux # swupd os-install /mnt --bundles=os-core,os-core-update,kernel-native
Error: unrecognized subcommand `os-install’
Usage:
but it seems that os-install is missing from repositories.
So how to try this method you suggested?
