Code:

sudo mount /dev/nvme0n1p2 /mnt
sudo nano /mnt/etc/fstab

after making changes ctrl-x y to save changes. If you’re not sure post the contents of /mnt/etc/fstab

Instead of commenting the whole line in fstab for the external, including mount options noauto or nofail can prevent boot failure that results from a problem with, or absence of, the external.

To expand on that a bit, the noauto option prevents partitions named in fstab from being automatically mounted at boot. This option is commonly used for things like CDs or plugin devices which will probably not be present at boot time, but it would also prevent the boot process from choking on a mount that was causing problems. The nofail option prevents fail messages from being logged if the device simply isn't found.

The nofail option prevents failing to reach the default target, instead getting dumped at a shell prompt without normal services like X and network started. To test, add option noacl to an EXTx partition in fstab on any installation with a 6.1 or newer kernel. It's happened to me lots of times in installing a first kernel post-6.0.x on an installation with an EXT2 boot partition for Grub.

4. I created the two partitions via a "Gary Explains" video on youtube, using $ sudo cfdisk /dev/sda

I suspect the original partition on sda listed in fstab no longer exist, henceforth the recommendation to comment out the line in fstab.

When I put this code into the terminal of the jump drive I used to boot ("try ubuntu"), the fstab seemed empty.

Here is the link to a pic of my terminal after typing that in: https://imgur.com/a/R0id9J4

Am I doing this wrong?

Ladywolf, as long as you upload to imgur.com, I see none of your images. Images attached here, or to paste sites that don't require scripts enabled, I get to see.

Sorry, I didn't realize that.

Here are the previous pictures I posted. Hope this helps! And thanks for reading my thread and thanks in advance for the help!

Those messages indicate most likely either sudo mount /dev/nvme0n1p2 /mnt failed, or was the wrong command was used to attempt to mount the installed system's / filesystem.

Sounds good, thank you. So now that we have a possible diagnosis, how would I go about fixing this problem? If possible, be specific because I am still semi-new to linux.

colorpurple21859 · 12-10-2023, 02:34 PM

post the output of the following:

Code:

sudo mount /dev/nvme0n1p2 /mnt
ls /mnt

Please provide a more useful lsblk -f | grep -v loop, preferably by editing the same post #41, adding the new image, and removing the old lsblk image.
