I’m working with chromeos 80 and am using debian buster in crostini. I want to use the snap package manager. When I try:

~$sudo snap install hello-world
error: system does not fully support snapd: cannot mount squashfs image using "squashfs": mount:
   /tmp/sanity-mountpoint-962423259: mount failed: Operation not permitted.

How can I get this working?

  3. Under CentOS 8 we have a file /etc/modprobe.d/CIS.conf with all unused file systems disabled. Removing the line: install squashfs /bin/true resolves the error
