I'm following this example on developer.ubuntu.com to test before I "snap" my own creation. However, at the end I'm not allowed to run:
sudo snap install ros-example_1.0_amd64.snap
I get the following error:
ZOE ERROR (from /usr/lib/snap/snap): error checking HMM file
ZOE library version 2006-07-28
How do I solve this? Do I need to set some environment variable?
EDIT: I'm using 14.04 LTS. Is 16.04 required to create snaps?
