boot messages with errors

When I restart my Ubuntu 18.04 system, it suddenly crashes and shows a long list of [FAILED] messages as shown above, for example:

[FAILED] Failed to mount Mount unit for gtk-common-themes, revision 1198
See 'systemctl status "snap-gtk\\x2dcommon\\x2dthemes-1198.mount"' for details

and other mount errors like

[FAILED] Failed to mount FUSE Control File System

What could be the problem here, and how can I fix it?

  • I welcome to ask ubuntu. If you can copy and paste the output of the error into your question and wrap it in code brackets {} that would be awesome. thanks! – Joshua Besneatte Jul 24 '19 at 21:51

  • The error will be stored in /var/log/ (probably kern.log or syslog) Oh and regarding the image: you need the 1st error... what you show us are results from a previous problem. – Rinzwind Jul 25 '19 at 10:36
  • thanks@ Rinzwind sorry when I restart my laptop only this error come on my screen – Abhirock Jul 25 '19 at 10:39
  • Looks like you have a corrupt system. You can boot into Live Ubuntu and try running fsck to repair the system. If that doesn't work and you don't have a an image back-up of your system, you're looking at a re-install. – Paul Benson Jul 25 '19 at 14:32
