Bug#779960: apt-get remove doesn't respect dependencies' manual-flag
Package: apt
Version: 1.0.9.6
Severity: normal
Dear Maintainer,
* What led up to the situation?
While trying to minimize the size of my docker image, I wanted to remove build-only dependncies while leaving runtime dependencies intact.
I first installed runtime libs, then the -dev packages.
When removing the -dev packages, I noticed that some of the packages manually installed were auto-removed, because they were found to be "unecessary".
* What exactly did you do (or not do) that was effective (or
ineffective)?
As a workaround, we avoid remove, and only use apt-mark auto && apt-get autoremove.
* What was the outcome of this action?
Some manually installed packages were automatically removed.
* What outcome did you expect instead?
Only the packages mentioned in apt-get-remove and their automatic deps should be removed.
Any dependencies flagged as manual should remain intact.
