What version of snap-confine/ubuntu-core-launcher are you using? I ask because I noticed a bug in snap-confine in xenial-proposed where CLONE_NEWUSER got EPERM but with ubuntu-core-launcher from xenial release it worked. Curious if these are at all related.
Please provide output from:
$ apt-cache policy ubuntu-core-launcher snap-confine
