Are you saying that you first boot from the image, and then you run ubos-install to some disk, and then you boot from that disk?
Yes that is exactly what I wanted to say.(I followed below procedure according to the UBOS documentation)
1. Making a boot stick and starting with it.
2. Running sudo ubos-install dev/sda
3. Reboot, update, etc
I felt weird since it behaved differntly compared to the past time. Previously it becomes yellow channel even if I run ubos-install without that argument.
Is this change a fresh new one?
Your assumption is right, though there remains a question.
According to the normal process, when invoking "ubos-install"
UBOS defaults to the green channel, then it would be changed to the yellow channel if setting of the configuration files "channel" and "pacman.conf" is to be changed to yellow and updated.
So it changes its channel name to yellow, but the app list still remains to green.
Is this situation also normal?
Anyway I think this time it should be able to work. Thanks.
