How To Fix “Failed to start Snappy Daemon” Error in Ubuntu 18.04

Ubuntu 20

If you’re an Ubuntu 18.04 user, you may have encountered the error message “Failed to start Snappy Daemon” during the boot process. This issue can be frustrating, but don’t worry – this guide will walk you through several steps to resolve this problem.

Understanding the Snappy Daemon

Before we dive into the solutions, it’s important to understand what the Snappy Daemon is. Snappy Daemon, or snapd, is a background service that manages and maintains your snaps. Snaps are containerized software packages that are simple to create and install. They auto-update and are safe to run. If snapd fails to start, it can prevent these snaps from functioning properly.

Checking the Boot Process

The first step to troubleshooting this issue is to check the boot process. If you see the error message during boot, try pressing Ctrl+C. This command interrupts the current process and in some cases, it may allow the boot process to continue.

Viewing the Detailed Log

If you’re able to boot your system, you can check the detailed log of the snapd service for more information. This can be done by running the command journalctl -u snapd.service. Here, journalctl is a command that queries the contents of the system journal, -u is a unit option that filters output by SYSV or systemd unit, and snapd.service is the unit we’re interested in.

Checking the Status of the Snapd Service

Another useful step is to check the status of the snapd service. This can be achieved by running the command sudo systemctl status snapd.service. The systemctl command is used to examine and control the systemd system and service manager, and the status option is used to view the status of a service. The sudo command is used to run the command as an administrator.

Upgrading the Kernel

If the above steps don’t resolve the issue, you may need to upgrade your kernel. This can be done by running the commands sudo apt update and sudo apt full-upgrade. The apt command is used to handle packages in Ubuntu, update is used to resynchronize the package index files from their sources, and full-upgrade is used to upgrade the system by removing/installing/upgrading packages.

Reinstalling Snap

If upgrading the kernel doesn’t solve the issue, you may need to uninstall and reinstall snap. First, use the command snap list to find the installed snaps. Then, remove the installed snaps using sudo snap remove <packages-from-snap-list>. After that, remove snapd by running sudo apt purge snapd. Finally, remove the snap directory from your home directory with the command rm -rf ~/snap.

Conclusion

Resolving the “Failed to start Snappy Daemon” error can be a complex process, but with patience and the right steps, it’s definitely achievable. This guide has provided you with several steps to troubleshoot and fix this issue. Remember to always back up your data before making any significant changes to your system.
