You are making common mistakes like spelling errors (`ncureses-dev`). Are you really asking us how to fix your own typo? Advice: Check your input before hitting ENTER.

Seems clear that you are following some kind of instructions, but you have not provided a link to those instructions. Maybe the instructions are wrong. Or maybe you have failed to follow the instructions properly. We cannot know the answer since we lack those instructions.

Advice: Fix your `113 not upgraded` before you try to install anything new.

`113 not upgraded` - in addition to above, this is a clue that your package management is a mess. Are you running `sudo apt update` and `sudo apt upgrade` before installing new software? If you are neglecting keeping your system updated and you keep installing new software, you could really mess things up. In particular, if you don't use `sudo apt update` to update the list of available packages before performing other tasks in `apt` you run the risk of installing incompatible versions of software and landing yourself in dependency hell

If and when you [edit your question](https://askubuntu.com/posts/1358005/edit) and add all the information requested above, also include the distro and version of Linux you are using.

This is because there are no packages with the names ncureses-dev, libel f-dev, and dison in the Ubuntu repositories, which you can check yourself at packages.ubuntu.com.

It is unclear what you want to achieve, and the question title (setting up kernel) does not seem to be relevant to the rest of the question. You should rather ask a question specifically about what you are trying to do.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
