Comment 4 for bug 1727768

To request removal of a package only in Ubuntu, just file a bug against the package in Launchpad explaining the reason.

Run this command to check if any other packages depend on it:
reverse-depends src:sjterm

Then subscribe ubuntu-archive to the bug.

The subscription part is mentioned at the very top of this article (written mostly for the Archive Admin team since nearly all of it requires privileged access.)

Thanks for helping to make Ubuntu better!
