Behebung des Fehlers „Abschnitt ohne Paket:Kopfzeile gefunden“ in Ubuntu

Heute bin ich auf den folgenden Fehler gestoßen, als ich versuche, mein Ubuntu 20.04 LTS-Desktopsystem zu aktualisieren.

$ sudo apt update

Beispielausgabe:

Reading package lists... Error!
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/ny-mirrors.evowise.com_ubuntu_dists_focal_universe_binary-i386_Packages
E: The package lists or status file could not be parsed or opened.

Ich habe es noch einmal mit dem Paketmanager von Graphical Synaptic versucht. Aber kein Glück! Ich habe den gleichen Fehler!

Dies ist eines der häufigsten Probleme in Ubuntu- und Debian-basierten Systemen.

Nachdem ich die Ausgabe ein wenig sorgfältig gelesen hatte, verstand ich, dass die Paketlisten oder die Statusdatei aus irgendeinem Grund beschädigt sind, sodass sie nicht analysiert werden konnten.

Für diejenigen, die sich fragen, enthält die Statusdatei die Informationen über die installierten Deb-Pakete. Wir können dieses Problem lösen, indem wir die beschädigte Paketliste und Statusdatei entfernen und sie wie unten beschrieben neu generieren.

Behebung des Fehlers „Abschnitt ohne Paket:Header gefunden“ in Ubuntu

Schritt 1. Entfernen Sie zuerst die beschädigte Paketliste mit dem Befehl:

$ sudo rm /var/lib/apt/lists/* -vf

Der obige Befehl löscht alle Paketquelllisten von Ihrem Ubuntu-System.

Hier ist die Beispielausgabe von meinem Ubuntu 20.04 LTS-Desktop:

Schritt 2. Führen Sie nun den folgenden Befehl aus, um die Paketquellliste neu zu erstellen:

$ sudo apt update

Dies wird eine Weile dauern, abhängig von Ihrer Internetgeschwindigkeit. Sei geduldig!

Schritt 3. Führen Sie nach der Neugenerierung der Paketliste eine vollständige Aktualisierung durch, indem Sie die folgenden Befehle nacheinander ausführen:

$ sudo apt update

$ sudo apt upgrade

$ sudo apt dist-upgrade

Schritt 4. Löschen Sie nach der Aktualisierung des Ubuntu-Systems den Paketcache:

$ sudo apt autoclean

$ sudo apt autoremove

Schritt 5. Schließen Sie abschließend alle geöffneten Programme und starten Sie Ihr System neu:

$ sudo reboot

Das Problem sollte jetzt behoben sein.

Schritt 6: Falls Sie immer noch denselben Fehler sehen, entfernen Sie die Statusdatei und erstellen Sie sie mit den folgenden Befehlen neu:

$ sudo rm /var/lib/dpkg/status

$ sudo touch /var/lib/dpkg/status

$ sudo apt update

Vergessen Sie nicht, ein vollständiges Systemupdate durchzuführen und den apt-Cache zu leeren und dann Ihr System neu zu starten.

Hoffe das hilft.
