You can uninstall or removes an installed caps package itself from Debian 9 (Stretch) through the terminal,
$ sudo apt-get remove caps
If you would like to remove caps and it's dependent packages which are no longer needed from Ubuntu,
$ sudo apt-get remove --auto-remove caps
If you use with purge options to caps package all the configuration and dependent packages will be removed.
$ sudo apt-get purge caps
If you use purge options along with auto remove, will be removed everything regarding the package, It's really useful when you want to reinstall again.
$ sudo apt-get purge --auto-remove caps
