Slow Shutdown – A stop job is running for Snappy Daemon

The shutdown process in Ubuntu 18.04 or Ubuntu 19.10 machine sometimes is really slow. It gets stuck at purple screen with Ubuntu logo and the dots for quite a few seconds.

Press F2 on keyboard when shutting down Ubuntu. It prompts that ‘A stop job is running for Snappy Daemon’ with a timer (1min 30s) at the end.

It is obviously an issue stopping the snappy daemon. I DON’T know how to fix the problem unless removing all snap applications and the daemon.

A workaround to this problem is to reduce this timeout, from 90s down to for example 10s.

1. Open terminal (Ctrl+Alt+T) and run command to edit the /etc/systemd/system.conf file.

sudo gedit /etc/systemd/system.conf

When the file opens, change the line #DefaultTimeoutStopSec=90s to DefaultTimeoutStopSec=10s and save it.

2. Then either reboot or run command to reload the systemd daemon.

systemctl daemon-reload
