You have not given us enough information.

Do you have any clue why it failed? Is the disk full?

No. I am typing on it right now. It's fine.

I am using the Unity remix -- I tried MATE again recently and I don't
like it much. There are trivial glitches in the Unity remix but the OS
is solid.

When a Linux machine has serious disk filesystem problems, it mounts
read-only to protect your data. This is standard operating procedure
(SOP).

What you should do:

[1] Boot from a USB key with the same or newer OS version (in case the
filesystem code has changed in an update)

[2] Back up your data if you haven't already. Actually even if you
have already. You should have 3 backups, ideally.

To another drive, not a different partition but another physical
drive. Disk space is cheap. Have lots, and label them, with something
that won't fall off. Sticky labels are good.

Do you have your /home directory on a separate partition? If not, I
recommend this in future.

*Then*

[3] Reboot from the key and check and repair your root filesystem

[4] If this works, reboot off the key again. Check the root FS looks
OK, and can be checked again without error

[5] Boot from the affected partition. Check it starts OK.

Now run the package recovery steps it lists in the error you give above.

If it works, reboot.

[6] Then finish the update:

sudo apt install -f
sudo apt full-upgrade -y

Then reboot again.
