Is there a way to retrieve the list? I need help URGENTLY

I am glad to send you one but you need to tell me what version you are on. I have Kubuntu 18.04 and 20.04 available.

I use 18.04. Could you also pass me the folder "sources.list.d"? Inside there are 4 texts if I am not mistaken and there is one that is wrong. in the "apt" folder there are supposed to be 3 loose texts. The one that should be called "sources.list" has the name "sources.list.save.1" as if it were a copy of each other. I do not understand and i cant modify it
