I/O error and read only file issue

I downloaded Ubuntu because I need to run linux software (MUMmer, a bioinformatics tool) on my PC. Im trying to follow this websites instructions: https://docs.microsoft.com/en-us/windows/wsl/setup/environment#set-up-your-linux-user-info and I get to the step where I need to update and upgrade packages and I have to type:

sudo apt update && sudo apt upgrade

and I get these errors: first error

I tried googling it and it said to try:

sudo apt-get update

but when I did, I got these errors:

and it said to try

sudo apt-get install wget ca-certificates

but I got this error:

W: Not using locking for read only lock file /var/lib/dpkg/lock-frontendW: Not using locking for read only lock file /var/lib/dpkg/lockE: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

after runningsudo dpkg --configure -a

I get this error:

dpkg: error: unable to access the dpkg database directory /var/lib/dpkg: Read-only file system

I tried looking for solutions but I have no idea what all this is or means, unfortunately. I don't know what this /var/lib/dkkg directory is or where it is or what I need to do.

I tried ignoring this error and moving on to the other steps, for downloading anaconda, which I need to then download biocondnabut then I get this error:

wget: error while loading shared libraries: /lib/x86_64-linux-gnu/libpsl.so.5: cannot read file data: Input/output error

Any help would be much appreciated because I'm starting to dispair. Thank you in advance.
