-Your SDK chroot is too old! (or the version wasn't detected properly)
-As of v36 CoreOS has switched from python2.6 to 2.7 but the easiest way
-to upgrade is to recreate the chroot. On the host system please run:
-
- repo sync
- ./chromite/bin/cros_sdk --replace
-
-Note: This will delete your existing chroot (but not your source tree)
-so if you have anything kicking around in there like fancy dot files in
-chroot/home/$USER be sure to copy them elsewhere first!
