Snapcraft

[Vani Desai]

Thanks Ted. Your suggestions worked. I see cherrypy webserver running at
launch. I can access cherrypy hello world webpage on my host PC browser.
I got rid of run.sh file. I started cherrypy webserver from YAML file.

I have few more questions

1. I see this message "Signature check failed, but installing anyway as
requested" when I install a snap on Snappy QEMU. How do I get valid
signature for my snap?

2. I installed snappy example py3-project on Snappy QEMU. It has
sha3sum.py. I can't run that python program on Snappy. How to execute
program installed with Snap manually?

3. I have webdm installed on Snappy QEMU.I am not able to access webdm from
my host PC browser. I tried webdm.local:8080 or localhost:8080

Thanks,
Vani
