I was able to reproduce this on a classic 16.10 system only after upgrading the ubuntu-core snap and policy since that is where snap reexec is used. Ie, with:
snap-confine 1.0.41-0ubuntu2 snapd 2.13+16.10 $ cat /proc/version_signature Ubuntu 4.8.0-11.12-generic 4.8.0-rc6 $ sudo snap install ubuntu-core --channel=edge $ sudo snap install hello-world $ snap list Name Version Rev Developer Notes hello-world 6.3 27 canonical - ubuntu-core 16.04.1 687 canonical - $ hello-world Segmentation fault $ grep audit /var/log/syslog ...

One way to do this is: $ sudo snap refresh ubuntu-core --channel=edge $ sudo snap remove hello-world $ sudo snap install hello-world $ hello-world Segmentation fault -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1626121 Title: strict mode snaps crash with Segmentation fault on 16.10 To manage notifications about this bug go to: https://bugs.launchpad.net/snap-confine/+bug/1626121/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
