20.04 snapd issue: "system does not fully support snapd: cannot mount squashfs image..."
8,514
As you're on a VPS, maybe snaps is not supported on your env. I found this post on letencrypt, and someone said:
snaps rely on certain Linux kernel features which are not available under containerized servers like those running under openvz.
Hope this help.

I'm running Ubuntu 20.04 on a VPS. I want to install certbot, but I'm having issues with squashfs - here's what I get when I
sudo systemctl status snapd
(obviously, I was lead to this error when attempting to install certbot):● snapd.service - Snap Daemon Loaded: loaded (/lib/systemd/system/snapd.service; enabled; vendor preset: enabled) Active: inactive (dead) since Wed 2021-05-26 10:56:39 EDT; 16min ago TriggeredBy: ● snapd.socket Main PID: 166 (code=exited, status=42) May 26 10:56:34 vps70508.inmotionhosting.com systemd[1]: Starting Snap Daemon...

sudo apt install fuse squashfuse
did not help in my case. -
shortmort37 almost 3 yearsOhmigosh! That article was the antidote - I jumped over the snapd stuff and went right to the
sudo apt install certbot
and it installed just fine. Got my cert, and I am off and running. Many thanks, @MrLeakim !
