Upgrade Blocked

[ubfan1]

You can just highlight the blkid output with the mouse (left click and drag), then cut it (ctrl+shift+c) and paste it (ctrl+v) into a message here, no images needed.

Here is the result of the blkid ask. Next step was to open the root partition and check /etc/fstab. I am not sure exactly how to do that. Through the file manager I find a folder called root, then open in file manager and enter /etc/fstab and get "permission denied" The root directory has a big red X on it, by the way. Opening the properties show "contents unreadable". HELP
Once again, would there be any future in trying to just download the upgrade again?

. Next step was to open the root partition and check /etc/fstab. I am not sure exactly how to do that."

Like this:

less /etc/fstab

Should produce something like:

# /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 and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/ubuntu-vg/ubuntu-lv during curtin installation

# /boot was on /dev/sdc2 during curtin installation
/dev/disk/by-uuid/31ce1973-70eb-434b-9d53-158685cb189c /boot ext4 defaults 0 1
# /boot/efi was on /dev/sdc1 during curtin installation
/dev/disk/by-uuid/DA34-E212 /boot/efi vfat defaults 0 1
/swap.img       none    swap    sw      0       0

Looks like a typo somewhere, the actual UUID is as blkid reported:6496c978-c968-4bdf-8a40-f3b3f0b0233b The error message has ...fb3f0... missing a 3

[CowDoctor]

ubfan1, yes it is my typo. the UUIDs are identical. I dropped a 3 when typing the error message.

Dear Friends,
So sorry this is taking so long. Here is the response to less /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 and removed. See fstab(5).
#
# <file system>  <mount point>  <type>  <options>  <dump>  <pass>

# /dev/sda2
UUID=6496c978-c968-4bdf-8a40-f3b3f0b0233b  /  ext4  noatime,errors=remount-ro  0  1

# /dev/sda1
UUID=E980-6849  /boot/efi  vfat  umask=0077  0  1

# /dev/sda3
UUID=748c985b-1fe1-4dac-9dae-b3b8190a8652  none  swap  sw  0  0

What next? Sorry to be so helpless.
Yours hopefully,

ps, once again, since I can get this machine kind of running in recovery mode, would it be worth trying to download Ubuntu 24.04 again and see if it straightens things out?

CowDoctor; Ouch

Your /etc/fstab file does not in almost all respects agree with what blkid reports.

Let's see what we can do to make it right.
Post back:

sudo fdisk -lu
swapon --summary

so we know what the boot partition is and *IF* there is a swap partition.

maybe, this is all there is to it

[CowDoctor]

Thank you. This, I believe, is the relevant part of the response to the fdisk request:

Disk /dev/sda: 111.8 GiB, 120040980480 bytes, 234455040 sectors
Disk model: WDC WDS120G2G0B-
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: BA5E4D98-D80E-415E-A1C7-9ADE1CE33BBB

Device         Start       End   Sectors   Size Type
/dev/sda1       2048   1050623   1048576   512M EFI System
/dev/sda2    1050624 226064383 225013760 107.3G Linux filesystem
/dev/sda3  226064384 234452991   8388608     4G Linux swap

There were 38 loops reported, all nearly identical except for some numbers in the first lines. The above code between loops 7 and 8.
I can copy the whole thing if you wish.
and here is the swapon:

oe@Bucky:~$ swapon --summary
Filename                Type        Size        Used    Priority
/dev/sda3              partition    4194300        0    -2

Hope this is useful

CowDoctor; Well yeas

All looks good - and all agrees. (why using code tags is so important, as I did goof in reading)

OK go back and verify that the UUID 6496c978-c968-4bdf-8a40-fb3f0b0233b is a typo on your part relaying to the post.

else we got to go hunting.

it's in the process
