Comment 0 for bug 1840122

Test Case:
1. Boot eoan desktop to a live session
2. Wait a couple of minutes until snapd settles
3. Reboot from gnome menu

Expected result:
The system reboots

Actual result:
The systems fails to reboot or shutdown and displays some errors about failing to unmount /cdrom and squashfs errors in a loop.

This also causes daily tests to fail.
