Hello everyone,

I also got one error before that
error:could not create usr/lib/liota permission denied
I am running ubuntu core 16.04 on VM of my MacBook
can anyone suggest the possible reason

did you use snapcraft login ? (also do not run snapceaft with sudo … )

I have logged in snapcraft and that was successful after that used “push snapcraft xyz.snap” command.
But, got the same error. Find the details as below
Login successful.
ashish@ashish-VirtualBox:~/liota$ snapcraft push liota_master_amd64.snap

well, it should work if you did login and registered the name with snapcraft register (unless the name is already owned by someone else)

Thanks for support, will try again.
