私は最近do-release-upgradeを試みましたが、残念ながらプロセスが中断され（sshを介してのみアクセスできるリモートシステムです）、今は解決できない壊れた依存関係がたくさんありました。また、満たされていない依存関係のために他のパッケージ（apache2など）をインストールすることはできません。 （簡単な）システムの歴史：
- 過去ある時点にはUbuntu 13.04がありました（希少）。
- 後でUbuntu 13.10（いたずら）をインストールしました。
- ある時点では、source.listに混合ソース（希少で愉快な）があったようですが、なぜそうなのか覚えていません。
- サードパーティのソースもあります（特にvirtualminをインストールしたかったのでインストールしました）。
今：
- このシステムを最新のLTSバージョンにアップグレードしたいと思います。私はいくつかのステップ（13.10 - > 14.04、その後LTSバージョンアップグレード14.04 - > 16.04）を経てこれを行うことにしました。これを行うには、すべてのサードパーティのソース（実際にはvirtualminだけ
apt updateを考えています）を削除し、「raring / saucy」を「trusty」（14.04）に置き換えますdist-upgrade。私はそれがうまくいくと思いますが、このシステムを長く使用していません。 - その後、リリースが14.10の代わりに次のLTSバージョン「Xenial」（16.04）にアップグレードできるように編集して
/etc/update-manager/release-upgrades設定しました。Prompt=ltsそれから公演をしましたdo-release-upgrade。 - 残念ながら、プロセス中にコンピュータ（リモートコンピュータ）へのインターネット接続が失われ、インストールが終了しませんでした（ほぼ終了したと思いますが）。
ここにあります。

しかし、上記の出力方式は「xenial」だけが現れるものとみなして混合ソースがないことを確認させてくれるようです。私のsource.listにはxenial行だけがあります。

残念ながら、適性はこれらの依存関係を解決する解決策を見つけることができませんでした。推奨される回避策は、すべてのパッケージに対して「次のパッケージを現在のバージョンに保つ」ことです。
どんな助けでも歓迎します...

レポに「メイン」はありません！そのため、「package_xxxにはpackage_yyyバージョンaaaが必要ですが、バージョンbbbはすでにインストールされています。」型の破損した依存関係がたくさんあります。 「マスター」リポジトリがないため、必要な新しいバージョンをインストールできません。
