How to overwrite a previously uploaded malformed upstream tarball in Launchpad's PPA?

Question

I have been maintaining a PPA for quite a while for an open-source project. On the new release of the program, I compiled the .deb package accidentally with a malformed upstream tarball and uploaded it.

The build failed obviously, but then, I changed my upstream tarball to the right one but PPA is rejecting my upload with such message:

File <filename> already exists in <name>, but uploaded version has different contents.

So my question is..

How do I overwrite that file? I just want to reupload with a different tarball. I bumped the version in the debian/changelog but that changed nothing

You'll have to upload the correct tarball under a slightly different name. It's conventional to append something like +ds in this kind of case: so foo_1.0.0.orig.tar.xz → foo_1.0.0+ds1.orig.tar.xz (and bump your changelog version from 1.0.0-1 to 1.0.0+ds1-1, etc.). If you do it with this scheme then you should be able to drop the +ds suffix at the next upstream release.
