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

Options to Fix

Reconfigure dpkg Database

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

# 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

Force-Install the Software

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

# 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

Note: Dependencies are other software packages that are required by the software you are installing

• A package manager helps keep track of dependencies for you

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

# 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

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If an old, outdated, or unused package is causing the problem, you can solve the problem by removing unused software packages

# apt autoremove

Note: Avoid the next 2 options unless all other methods have failed

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

# 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

# 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

# apt-get update

After which you can re-install the broken software again

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

# dpkg –i ––force–overwrite /var/cache/apt/archives/full_name_of_package

Note: If you do not know the actual name of the package, you can search for it with the following command

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

Replace package_name with the name of your software

• This should return any instances of that package name
• Note the exact filename, and type it into the previous command
