If you previously put a hold on a package, : will remove it, but then again,
if a package was on hold, choosing to upgrade them all should honor that.
Note that sometimes, pressing : won't seem to have any effect. This is
because another package you're choosing to install / upgrade conflicts with
that package, and you'll need to cancel the pending operation on that
package as well. If the conflict resolution dialog doesn't come up, then
press g once to review the pending operations. The package you're wanting
to hold should be in the list of packages to be removed due to unsatisfied
dependencies. If you highlight that package, the information pane will
tell you that another package conflicts with it, so it's being removed.
You can then search for that package, cancel its pending operation, and
unless there's another dependency, your original package will now be
properly held back from the upgrade.
After you change the preview (the tab you're in after you press g once), it
will update, but I always use q to close that tab, then press g again to
generate the preview again, so I'm sure no packages are listed in
unexpected places.
Naturally, if you choose to review carefully what packages will be removed,
upgraded, or installed before pressing g again, you'll never be surprised
at what aptitude does. This is why I never understood how people can have
aptitude remove packages without them expecting it.
