Correzione dell'errore "È stata rilevata una sezione senza pacchetto:intestazione" in Ubuntu

Oggi ho riscontrato il seguente errore quando provo ad aggiornare il mio sistema desktop Ubuntu 20.04 LTS.

$ sudo apt update

Risultato di esempio:

Get:1 http://ny-mirrors.evowise.com/ubuntu focal InRelease [265 kB]
Hit:2 http://linux.teamviewer.com/deb stable InRelease

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.

Ho riprovato con il gestore di pacchetti grafico Synaptic. Ma senza fortuna! Ho ricevuto lo stesso errore!

Questo è uno dei problemi più comuni nei sistemi basati su Ubuntu e Debian.

Dopo aver letto un po' attentamente l'output, ho capito che gli elenchi dei pacchetti o il file di stato sono danneggiati per qualche motivo, quindi non è stato possibile analizzarli.

Per coloro che si chiedono, il file di stato contiene le informazioni sui pacchetti deb installati. Possiamo risolvere questo problema rimuovendo l'elenco dei pacchetti danneggiati e il file di stato e rigenerandoli come descritto di seguito.

Corretto l'errore "È stata rilevata una sezione senza pacchetto:intestazione" in Ubuntu

Passaggio 1. Per prima cosa, rimuovi l'elenco dei pacchetti danneggiati usando il comando:

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

Il comando sopra eliminerà tutto l'elenco dei sorgenti del pacchetto dal tuo sistema Ubuntu.

Ecco l'output di esempio dal mio desktop Ubuntu 20.04 LTS:

Passaggio 2. Ora, esegui il seguente comando per ricostruire l'elenco dei sorgenti del pacchetto:

$ sudo apt update

Ci vorrà un po' di tempo dipende dalla tua velocità di Internet. Essere pazientare!

Passaggio 3. Una volta rigenerato l'elenco dei pacchetti, esegui un aggiornamento completo eseguendo i seguenti comandi uno per uno:

$ sudo apt update

$ sudo apt upgrade

$ sudo apt dist-upgrade

Passaggio 4. Dopo aver aggiornato il sistema Ubuntu, svuota la cache del pacchetto:

$ sudo apt autoclean

$ sudo apt autoremove

Passaggio 5. Infine, chiudi tutti i programmi aperti e riavvia il sistema:

$ sudo reboot

A questo punto il problema dovrebbe essere risolto.

Passaggio 6: Per ogni evenienza se vedi ancora lo stesso errore, rimuovi il file di stato e ricostruiscilo usando i seguenti comandi:

$ sudo rm /var/lib/dpkg/status

$ sudo touch /var/lib/dpkg/status

$ sudo apt update

Non dimenticare di eseguire un aggiornamento completo del sistema e pulire la cache apt e quindi riavviare il sistema.
