<div class="gmail_quote"><div><div><div>Why does autoremoving the ubuntu-virt-mgmt metapackage fail to remove any dependencies, while autoremoving the virt-manager package works as expected?</div><div><br></div><div>Is there a difference in the way that metapackages are processed vs normal packages?</div>
<div>I looked at the debian/control on the source for both of them but didn't see anything out of the ordinary.</div><div><br></div><div>If they are treated differently, I'd like to know how to create a hybrid-metapackage.</div>
<div>When a hybrid-metapackage is autoremoved, it's dependencies should be removed with it.</div><div><br></div><div>From <a href="https://gist.github.com/3004812" target="_blank">https://gist.github.com/3004812</a> :</div>
