I can see some packages in the repo but I couldn't able to use `apt show` or `apt install` on that packages

Some packages like libprelude are marked as dependencies to some packages (Depends field in the control file), but I'm unable to read the control file using apt show. In fact I'm unable to use apt install against this package. But I'm able to download these packages using apt source. Any idea what's happening here?

package available in focal: https://packages.ubuntu.com/source/focal/libprelude

I'm using focal container.

`source` packages (the `deb-src` lines in your sources) are not the same as compiled binary packages. Source packages are NOT ready-to-run, and cannot be so installed by apt. Folks who do not quite grok the difference between source packages and binary packages should avoid source packages.

That link shows it is the source package for libprelude which means that it is not a compiled version so apt show won't work on it and neither will apt install. apt can only download it when you run apt source libprelude. However, apt show and apt install will work on all the other binaries listed below it on that page that are compiled from that source code, i.e. apt show libprelude28.

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.
