Fails to create a snappy image when using --install

[Ricardo Salveti]

Using ubuntu-device-flash 0.23-0ubuntu2 on vivid, I can't create a snappy image using the extra --install parameter (to bundle a snap from the store).

It works fine without using --install.

$ sudo ubuntu-device-flash core 15.04 --channel stable --oem beagleblack --install=hello-world --enable-ssh --output ubuntu-15.04-snappy-armhf-bbb.img

Can I get the output of lsblk?

[Sergio Schvezov (sergiusens)]

and the mount table before and after this happens?

[Ash Charles (ashcharles)]

Is there an updated version of the package available? I'm also seeing this on 0.23-0ubuntu2 of the ubuntu-device-flash package but I couldn't see if a more recent version had been made available in a PPA that includes this fix.

[Ash Charles (ashcharles)]

I used the package version 0.27-0ubuntu1 from https://launchpad.net/~snappy-dev/+archive/ubuntu/tools-proposed which included the fix.
