summary: Upgrade the core snap and revert a few times
details: |
Check that it is possible to upgrade and revert the core and snapd snaps
in Ubuntu Core 16 and 18. Ensure the bootloader configuration is correct
and the device is scheduled for auto-reboot in all cases
# ARM devices are not supported on ubuntu-core-18 due to fw_printenv/setenv are
# not provided by the system and as the devices boot with uboot so it is not
# possible to get any grub information as it is done with non arm devices.
systems: [ubuntu-core-16-*, ubuntu-core-18-64*]
# Start early as it takes a long time.

# uploading the core snap triggers OOM
