Mount snap "core" (3604) ([start snap-core-3604.mount] failed

Question

I tried to install Hugo with Snap on Ubuntu 16.04.3 LTS (GNU/Linux 2.6.32-042stab125.5 x86_64). Service snapd is running, but I get following error:

cannot perform the following tasks: - Mount snap "core" (3604) ([start snap-core-3604.mount] failed with exit status 1: Job for snap-core-3604.mount failed. See "systemctl status snap-core-3604.mo
unt" and "journalctl -xe" for details. )

systemctl status snap-core-3604.mount command gives following output:

● snap-core-3604.mount - Mount unit for core Loaded: loaded (/etc/systemd/system/snap-core-3604.mount; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Tue 2017-12-26 02:04:46 EST; 25s ago Where: /snap/core/3604 What: /var/lib/snapd/snaps/core_3604.snap Process: 15732 ExecMount=/bin/mount /var/lib/snapd/snaps/core_3604.snap /snap/core/3604 -t squashfs -o nodev,ro

I got same error, when I issued install command under root privileges.

The system you're running isn't pure Ubuntu 16.04.3. It is using a non-Ubuntu kernel 2.6.32-042stab125.5 x86_64 which is missing some of the critical features required by snapd and snaps themselves. I'd recommend either switching to a stock Ubuntu kernel (if possible), or request your provider updates their kernel.

I asked my VPS provider, but they said, SolusVM supports only current kernel version. – plaidshirt Dec 27 '17 at 17:13

Unfortunately you won't be able to run snaps on that system then I'm afraid. – popey Dec 27 '17 at 21:11

I fixed this problem on Raspberry Pi (Raspbian 9, Stretch), with a reboot after installing snapd.

After the reboot, the above error did not occur when doing e.g.

sudo snap install core; 
sudo snap refresh core
sudo snap install --classic certbot # for Let's Encrypt
