Решение проблемы Sub-process /usr/bin/dpkg returned an error code (1)

Попробуем исправить этот сломанный пакет.

Я покажу вам несколько методов, которые вы можете попробовать по одному.

Они простые в использовании и просто без проблем осуществимы.

Вы должны попытаться запустить sudo apt update, а затем попытаться установить новый пакет или обновиться после каждого из описанных здесь методов.

Способ 1: переконфигурировать базу данных пакетов

Первый метод, который вы можете попробовать, – перенастроить базу данных пакетов.

Вероятно, база данных повреждена при установке пакета.

Реконфигурация часто устраняет проблему.

sudo dpkg --configure -a

Способ 2: Использовать принудительную установку

Если установка ранее прервалась, вы можете попробовать установить пакет принудительно:

sudo apt-get install -f

Способ 3. Попробуйте удалить проблемный пакет.

sudo apt remove 

Способ 4. Удалите информационные файлы с информацией о проблемном пакете

Это должно быть вашим последним прибежищем.

Вы можете попробовать удалить файлы, связанные с пакетом, из /var/lib/dpkg/info.

Вам нужно немного узнать о базовых командах Linux, чтобы выяснить, что происходит, и как использовать их с вашей проблемой.

В моем случае у меня была проблема с polar-bookhelof.

Поэтому я искал файлы, связанные с ним:

ls -l /var/lib/dpkg/info | grep -i polar-bookshelf
-rw-r--r-- 1 root root 2324811 Aug 14 19:29 polar-bookshelf.list
-rw-r--r-- 1 root root 2822824 Aug 10 04:28 polar-bookshelf.md5sums
-rwxr-xr-x 1 root root     113 Aug 10 04:28 polar-bookshelf.postinst
-rwxr-xr-x 1 root root      84 Aug 10 04:28 polar-bookshelf.postrm

Теперь мне нужно удалить эти файлы:

sudo mv /var/lib/dpkg/info/polar-bookshelf.* /tmp

Introduction

The error message “Sub-process /usr/bin/dpkg returned an error code (1)” indicates a problem with the package installer. This can happen in Ubuntu after a failed software installation, or if the installer becomes corrupted.

The key phrase in this error is /usr/bin/dpkg. This refers to the dpkg package installer for Linux. A package installer is an application that tracks software, updates, and dependencies. If it is damaged, any new software installation will cause this error message.

We cover several possible solutions, from easily-solved and straightforward solutions to more complex processes. This guide will help you resolve the dpkg returned an error code 1 on an Ubuntu operating system.

Prerequisites

• A user account with sudo privileges
• A terminal window/command-line (Ctrl–Alt–T)

Method 1: Reconfigure dpkg Database

If your package database has become corrupted, reconfiguring it can repair it.

Enter the following command:

sudo dpkg --configure -a

This command reconfigures packages that have been unpacked but not necessarily installed. An interruption at the wrong time can cause this database to become corrupt. This is especially helpful if you were running installation and the process was interrupted.

Method 2: Force-Install the Software

If Method 1 does not work, you can attempt to fix the dependencies in the package installer.

Enter the following:

sudo apt-get install -f

The -f option means fix-broken. It repairs any broken dependencies in your package manager. Broken dependencies occur when a download is interrupted, or there is a problem with the cached download.

Method 3: Remove Bad Software Package

If you know which software caused the errors on your system, you can remove it.

Enter the command and package_name with the name of the software that is causing the problem:

sudo apt-get remove --purge package_name

The --purge option directs the system to remove config files in addition to uninstalling. This helps get rid of all traces of the offending software.

Method 4: Clean Out Unused Software Packages

If an old, outdated, or unused package is causing the problem, you can solve the problem by removing unused software packages.

Enter the following command in the terminal:

sudo apt autoremove

Method 5: Remove Post Files

If you know the name of the package that is causing problems, you can delete the files manually. The installation files are usually located in the /var/lib/dpkg/info file.

Type in the following command and replace package_name with the name of the broken software.:

sudo ls -l /var/lib/dpkg/info | grep -i package_name

This will generate a list of all references to the software you installed.

You can then remove them by entering:

sudo mv /var/lib/dpkg/info/package_name.* /tmp

This command moves the files to the /tmp directory, where they cannot affect your package manager.

Next, update the package manager:

sudo apt-get update

After which you can re-install the broken software again.

Method 6: Overwrite Package File

If you know the name of the package that is causing a problem, you can force an overwrite.

Use the following command and replace full_name_of_package with the actual package name:

sudo dpkg -i --force-overwrite /var/cache/apt/archives/full_name_of_package

ls /var/cache/apt/archies/*package_name*

Conclusion

The dpkg error message indicates that there is a problem with the package installer, which is  commonly caused by an interrupted installation process or a corrupted database.

By following these steps, you should now have several methods to fix the dpkg error message and attain a working package installer.

It’s not uncommon to run into an issue of broken packages in Ubuntu and other Debian-based distributions. Sometimes, when you upgrade the system or install a software package, you may encounter the ‘Sub-process /usr/bin/dpkg returned an error code’ error.

For example, a while back, I tried to upgrade Ubuntu 18.04 and I bumped into the dpkg error as shown below.

Errors were encountered while processing:
google-chrome-stable
E: Sub-process /usr/bin/dpkg returned an error code (1)

This indicates that the google-chrome-stable package is either broken or corrupt. There are a few workarounds to this problem, so don’t throw in the towel yet or discard your system.

Solution 1: Reconfiguring the dpkg Package

One of the triggers of this error is a corrupted dpkg database. This can be caused by the sudden interruption of the installation of a software package. Reconfiguring the database is one way to resolve this issue.

To do this, simply execute the command:

$ sudo dpkg --configure -a

This reconfigures the unpacked packages that were not installed during the installation process.

Solution 2: Force Install the Troublesome Package

Sometimes, errors can occur during the installation of software packages. When such happens, you can force install the package using the -f option as shown.

$ sudo apt install -f
OR
$ sudo apt install --fix-broken

The -f option & --fix-broken can be interchangeably used to fix broken dependencies resulting from an interrupted package or cached package download.

Solution 3: Purge the Bad or Corrupted Software Package

If the first two solutions did not fix the problem, you can remove or purge the problematic software package as shown.

$ sudo apt remove --purge package_name

For example, in my case, purging the Google chrome package fixed the issue.

$ sudo apt remove --purge google-chrome-stable

Then invoke the commands below to remove all the old, unused, and unnecessary packages which also frees up space on your hard drive.

$ sudo apt clean
$ sudo apt autoremove

Solution 4: Remove all the Files Associated with the Package

Lastly, you can manually remove all the associated with the troublesome package. First, you need to find these files which are located in the /var/lib/dpkg/info directory as shown.

$ sudo ls -l /var/lib/dpkg/info | grep -i package_name

After listing the files, you can move them to the /tmp directory as shown

$ sudo mv /var/lib/dpkg/info/package-name.* /tmp

Alternatively, you can use the rm command to manually remove the files.

$ sudo rm -r /var/lib/dpkg/info/package-name.*

Finally, update the package lists as shown:

$ sudo apt update

You can thereafter give it another shot in reinstalling the software package.

Conclusion

This type of dpkg error points to an issue with the package installer usually caused by the interruption of an installation process or a corrupt dpkg database.

Any of the above-mentioned solutions should fix this error. If you have come this far, then it’s our hope that the issue has been successfully resolved and that you were able to reinstall your software package.
