Thank you for this submission and updating docs.

Note that most of the curl replacements suggested in docs are not valid curl calls, please update and test them on a running system to make sure we are documenting functional equivalents without errors before we land it.

I'm curious which images streams you are familiar with where wget does not exist:
Looking at desktop manifest it still has wget in the image, same with ubuntu server images and ubuntu minimal images because it's pulled in by other image dependencies like pciutils which exist in most images.

These are not valid curl commands. We should update them to commands that can run without error if we want to land this.

My fail, see update please

"Ubuntu developers have decided to remove wget from the default install of Ubuntu Server 25.10, in favour of wcurl, which offers similar functionality." - from link
So I decide to help Canonical to drop wget totally.

@blackboxsw I don't know why the bot plans to close PR soon... But let's use curl instead of wget
