You need Swap on your device

I'm having similar issues, but got past the first error about "/dev/fuse". It seems like you must enable support for FUSE when installing manually/advanced (not sure if it's enabled with Default settings or not). I feel like this instruction should probably be added to the script's install page.
After trying again with that enabled, I get a different error (related to Swap, as @MickLesk indicated).

You currently have 4GB of memory on this system.
It is important to have a large swap file to reduce memory consumption with stopped
Workspaces and to ensure processes are not killed in session when running many Workspaces.
Depending on configuration a normal Workspace will consume 2-4GB of memory.

Note: opening the "kasm_install..." log does not provide any further info, because it's just a copy of what's shown on the screen.

So, I don't know how to enable Swap during the installation procedure.

[MickLesk]

Swap must be enabled on Host.

[nickshanks347]

Yeah, adding swap to my host fixed it. Please add this to the scripts' install page.

[supermarkert]

Same. Never needed it before, but followed a tutorial to add swap, and got it installed. I'd suggest this requirement (including the one about FUSE support) be added to the Install page as notice to users. Mandatory FUSE could probably be added to the script, if it's really required. There was no default option presented.

@supermarkert I guess we can remove "View Source" links on web page, as noone really reads it. FUSE is enabled by default

var_fuse="${var_fuse:-yes}"
var_tun="${var_tun:-yes}"

[supermarkert]

@tremor021
If I install using the "Advanced" option (not default), and walk through the steps, when I get to the FUSE option, "NO" is the default option:

At the very least, I'm suggesting this be mentioned on the install page that FUSE is required during install.

I now see the notes have been added to the site. Thanks!
