I was trying to mount an external drive that it wasn't recognising for some reason. I then went into disk utility, found a drive I thought was that one, went into the mount options for that drive and changed the option for it to use the automatic mount options. This was not the main drive my OS is on, but probably a remnant of the previous one I had. I am currently in safe mode trying to revert that setting using the root command prompt.



The latest Ubuntu version.



I changed the first one in the Disk Utility menu, under mount options, in what I thought was the ext drive.



So basically what I need is a command to switch off automatic mount options.



/# cat /etc/fstab
/etc/fstab: static file system information.

Use 'blkid' to print the universally unique identifier for a
device; this may be used with UUID= as a more robust
way to name devices
that works even if disks are added or removed. See
fstab(5).

<file system> <mount point> <type> <options> <dump>
<pass>

/boot was on /dev/sda1 during installation
UUID=9762da9f-b9f0-4a9f-9796-ab14d69b3f5f /boot

  • Your fstab is wrecked; to provide advice as to how to fix it, information about the UUIDs of your partitions is required. To provide that, edit your question and provide the output of sudo blkid. If your partition setup is complicated, further information may be needed.
