Re: Can't change Channel in Dualboot

 

Thanks Barry, Good info. I was able to get ubuntu-device-flash to attempt to install. I'm still on the learning curve, and I have grouper not Flo. :(  It looks like system-image-cli
 should do what I need, so I've installed it. Now I'm looking for a copy of the Manpage.

I don't dual boot - I've only ever flashed my device using
ubuntu-device-flash, which takes a --channel argument.  So something like this
will flash you to utopic:

$ ubuntu-device-flash --channel ubuntu-touch/utopic

Note the extended channel name containing a slash.  Channels were renamed a
while ago.  ubuntu-device-flash has a --list-channels option you can use to
list all available channels.

If you have shell access to your device, once you're booted into Ubuntu, you
can use the system-image-cli command to switch channels too.  Read the
system-image-cli manpage for more details, however it's pretty easy.

To see all available channels:

$ system-image-cli --list-channels

To switch channels, e.g.:

$ system-image-cli --switch ubuntu-touch/utopic

However, note that --switch only works with system-image 2.3.1 which isn't
available in Trusty.  No matter; --switch is just an alias for

$ system-image-cli -b 0 -c ubuntu-touch/utopic

Cheers,
-Barry
