I keep getting this error and I cannot do anything about it

So I have been getting this error, and I am not sure what to do with it as I cannot proceed in my work

Package docker-ce is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

Package docker-ce-cli is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

Does anyone know how to fix this issue? Thanks.

Please share a link to the installation instructions you are using and the output of cat /etc/os-release.

Make sure to share the output of the cat command as code block, by adding ``` in a separate line before and after the content.

I tried running the commands in Ubuntu and there was no output at all for some reason
Im sorry if I did it wrongly, but can you please elaborate a little on what I should do?

Please answer the first part as well. There is no joy in having to guess what people might have done to end up with the error message they shared.
