ChromeOS: error: system does not fully support snapd: cannot mount squashfs image using "squashfs": mount:

Question

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?

Answer 1

Under Redhat7 we have a file /etc/modprobe.d/NCIRC.conf with all unused file systems disabled. Removing the line: install squashfs /bin/true resolves the error here as well

Answer 2

On Centos or Fedora:

sudo dnf install squashfs-tools squashfuse

Answer 3

Try this way to install SNAPD

sudo apt install libsquashfuse0 squashfuse fuse 
sudo apt install snapd

Now select package name:

sudo snap install gimp 

Answer 4

Try: sudo modprobe loop
