Solution: Sub-process /usr/bin/dpkg returned an error code (1)

When I was trying to troubleshoot this error in the Ubuntu operating system. I found the solution for this.

The installer becomes corrupted that is the only reason we are getting errors. The key phrase in the error is /usr/bin/dpkg. Here, the dpkg is the package installer for Linux and it tracks software updates and dependencies.

Now, follow the below steps to fix the error dpkg returned an error code 1:

• Open the terminal

• Use the below code to move the dpkg info file into another file

sudo mv /var/lib/dpkg/info /var/lib/dpkg/info_silent

Here, we moved the info file into the info_silent file on the same path “/var/lib/dpkg/info_silent”. You can take any name for the new file (info_silent).

• Now create a new directory info in dpkg folder, use the below command

sudo mkdir /var/lib/dpkg/info

• Excute the update command to download package information from all configured sources

sudo apt-get update

• Excute the below command to check the dependencies of the packages you want and install any that are needed.

sudo apt-get -f install

Here, this command will install the MongoDB database and also check the dependencies that are needed to install.

• After installing all the dependencies move all the file of the info directory into info_silent directory.

sudo mv /var/lib/dpkg/info/* /var/lib/dpkg/info_silent

• Remove the info directory, use the below command

sudo rm -rf /var/lib/dpkg/info

• Now, again move all the file of the info_silent directory into the info directory.

sudo mv /var/lib/dpkg/info_silent /var/lib/dpkg/info

• Use the below code to updates the list of available packages and their versions

sudo apt-get update

• After updating the lists, the package manager knows about available updates for the software you have installed.

• Use the upgrade command to installs newer versions of the packages you have.

sudo apt-get upgrade 

also, update and upgrade

• Now we resolved the error and successfully installed the MongoDB without any error fall.

• Check the version of MongoDB, use the below command
