summary: Ensure classic dimension works correctly
details: |
Validates classic snap can be installed in uc16. Check that classic can
run commands inside classic and sudo works without a password inside
classic.
# classic snap is not maintained for UC18+, for these releases the lxd snaps is
# recommended instead of the classic snap
systems: [ubuntu-core-16-*]
environment:
# We need to set the SUDO_USER here to simulate the real
# behavior. I.e. when entering classic it happens via
# `sudo classic` and the user gets a user shell inside
# the classic environment that has sudo support.
SUDO_USER: test
prepare: |
echo "test ALL=(ALL) NOPASSWD:ALL" > /etc/sudoers.d/create-test
restore: |
rm -f /etc/sudoers.d/create-test
# Undo the change done by the classic snap.
# FIXME: https://github.com/snapcore/classic-snap/issues/32
