を使用しますapt list --upgradable
。
次の選択肢はapt-get --simulate upgrade
です。(@EightBitTonyに基づく)
さまざまなオプションからの出力を以下に示します(誰かに役立つことを願っています):
me@machine:~$ apt list --upgradable
Listing... Done
kubernetes-cni/kubernetes-xenial 0.7.5-00 amd64 [upgradable from: 0.6.0-00]
N: There are 3 additional versions. Please use the '-a' switch to see them.
me@machine:~$ apt-get --simulate upgrade
NOTE: This is only a simulation!
apt-get needs root privileges for real execution.
Keep also in mind that locking is deactivated,
so don't depend on the relevance to the real current situation!

apt-get manページから、
-s, --simulate, --just-print, --dry-run, --recon, --no-act No action; perform a simulation of events that would occur but do not actually change the system. Configuration Item: APT::Get::Simulate. Simulation run as user will deactivate locking (Debug::NoLocking) automatic. Also a notice will be displayed indicating that this is only a simulation, if the option APT::Get::Show-User-Simulation-Note is set (Default: true). Neither NoLocking nor the notice will be triggered if run as root (root should know what he is doing without further warnings by apt-get). Simulate prints out a series of lines each one representing a dpkg operation, Configure (Conf), Remove (Remv), Unpack (Inst). Square brackets indicate broken packages and empty set of square brackets meaning breaks that are of no consequence (rare).
だからあなただけを確認してくださいapt-get -s upgrade
。
特定のパッケージをアップグレードしたい場合は、apt-get install <package name>
既にインストールされている場合に更新します。ただし、すべての依存関係も更新する必要があり、それらが何であるかに応じて、多くの更新にカスケードする可能性があります。
パッケージの更新が遅れている場合は、apt-get install
いくつかの大きな更新(おそらくphp、apache2など)を実行するので、それらを保持して問題を確認し、apt-get upgrade
完了後に実行できます。

削除された古い依存関係がある場合は、実行apt-get autoremove
できます。ご覧のように、新しい依存関係のインストールが求められます。--only-upgrade
すなわち、あなたはそれらの瞬間の1持っていると誤って間違ったパッケージを入力フラグは必要ありませんが、あなたは、あなたが誤って既存のものをアップグレードするのではなく、新しいパッケージをインストールしないことを確実にしたい素敵な場合:
