Hi.

I was upgrading my debian testing and I noticed a different behavior between aptitude and dselect, and cannot explain why.

After upgrading with aptitude upgrade and aptitude full-upgrade, if I run dselect and do: update, select (without even touching _any_ package) and install, dselect proposes me to install newer packages that aptitude full-upgrade was ignoring.

Why is aptitude (or dselect) doing so?

Thanks,
Enrico.

The only thing I can think of is that Aptitude is only suggesting certain packages for upgrade due to their dependencies, whereas Dselect is seeing if package_a.version < package_b.version.

If you try and run "aptitude upgrade" is there a list of packages that are being held back?

No, aptitude didn't show any held back package. That's what sounded strange to me. Even if I didn't check and now I cannot retrieve the list of packages which dselect installed, I think that they were not upgraded, they just were new packages which dselect decided to install, while aptitude didn't upgrade, correctly, because they were installed.

So, if this is what happened, I would like to understand the reason of this behavior. Moreover, if new packages were included in the base installation, it looks correct to me installing them.

Thanks,
Enrico.
