I would like to see if there is a way to check if a package got renamed/removed from package repositories on a new Ubuntu release(ex 20.04 --> 20.10). This also applies to packages in other package repositories(already added to apt's cache).
I have thought of using

apt show $PACKAGE_NAME > /dev/null

and checking the exit status of the command to see if that particular package exists.

  • Since 21.04 has not be released yet any question regarding it is off topic.

Try the rmadison command, included with the devscripts package. It's a simple python3 script (you can edit it) that queries the madison databases for each release.

Here's an example of rmadison in action. Let's look at the chromium-browser package, which changed a couple years ago. The deb package was replaced by a placeholder that merely installs the snap package. You can easily see the difference.

$ rmadison chromium-browser

  • That is helpful, but not exactly what I was looking for. In addition, after checking rmadison, it does only do system repositories (not repositories added by me).

  • Also, I think a better version of your answer would use sudo apt update && apt-cache madison $PACKAGE_NAME because that includes packages not in system repos.
