apt-get returns 1 when you press n, so ppa-purge goes onto to try the fallback (aptitude), seemingly that runs without even asking.
The fallback was meant to catch the case where apt-get gets confused by the revert list not being 100% accurate. That should be much better in the new version in Xenial, but its still possible to hit that case, if there are packages with cross-ppa dependencies for example. ** Changed in: ppa-purge (Ubuntu) Status: New => Triaged ** Changed in: ppa-purge (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1408031 Title: Requesting purge to abort fails.
