That could be resolved by looking at FromUser but the check you quoted is from 1999, while the FromUser parameter (that I added I might add) is "only" from 2009. After a quarter century of this behaviour, I am not sure it is worthwhile to "fix" this given, if I really tried, I could probably argue in favour of either way. I could frame that "decision" from 2009 a compat one given that FromUser was a new parameter and defaults to true, so that would have been a behaviour change if I had changed that… but I doubt I was thinking about that back then. So, absolutely not a fundamental design decision; just something that happened due to dumb luck/cosmic intervention/reasons. > I've CC'ed the APT team on this e-mail to get their input. If there are good (That CC'ed worked & the Fwd reached us a bit later, too. Some hop in between you, mailing list and you has probably greylisted the mail for a while making it look like it didn't reach us I suppose. No worries anyhow.) > fix."

I think for an interactive graphical tool like Synaptic this behaviour of libapt might be unfortunate, but easy to work around: If you see in Step 3 that a package is marked for complete removal already, just MarkKeep it first before MarkDelete it again.
