In the world of system administration, dependency issues are a common occurrence. One such issue that has been reported by users is the need to downgrade
libssl1.0 to install npm on Ubuntu 20.04 LTS. This article aims to provide a comprehensive guide on how to handle this situation.
Understanding the Issue
libssl1.1 is not compatible with the npm installation. The suggested solution in this scenario is to downgrade
However, it’s important to note that downgrading from a newer version to an older one can have implications on your system, as it involves replacing updated software with a potentially less secure or less feature-rich version.
The good news is that in this particular case, the downgrade is not as drastic as it may seem. The suggested downgrade is from
libssl1.1 version 1.1.1g-1+ubuntu18.04.1+deb.sury.org+1 to version 1.1.1f-1ubuntu2. The differences between these versions are relatively minor, mostly involving bug fixes and the addition of optional features.
To install npm, you can follow the solution provided by Dan Scally. This involves downgrading
libssl1.1 to the specific version required by
libssl-dev and then installing npm. Let’s break down the steps:
libssl1.1Use the following command to downgrade
In this command,
sudo apt install libssl1.1=1.1.1f-1ubuntu2
sudogives you administrative privileges,
aptis the package handling utility,
installis the command to install or upgrade packages, and
libssl1.1=1.1.1f-1ubuntu2specifies the package to be installed along with its version number.
- Install npm
After downgrading, you can install npm using the following command:
This command follows the same structure as the previous one, with
sudo apt install npm
npmbeing the package to install.
This solution has been reported to work without any issues.
In conclusion, downgrading
libssl1.0 is not necessary to install npm on Ubuntu 20.04 LTS. Instead, downgrading to the specific version required by
libssl-dev should resolve the dependency issue and allow you to install npm successfully. Always remember to understand the implications of downgrading software versions and consider all possible solutions before proceeding.
libssl1.0 are libraries that provide cryptographic functions in the OpenSSL toolkit. They are used by various software applications to ensure secure communication and data encryption.
The need to downgrade
libssl1.0 arises when there is a compatibility issue between the version of
libssl1.1 installed on your system and the version required by npm. Downgrading to the specific version required by npm resolves this dependency issue.
Downgrading software versions can have implications on your system. By downgrading
libssl1.0, you may be replacing a more updated and potentially more secure version with an older one. It’s important to consider the security and feature differences between the two versions before proceeding with the downgrade.
libssl1.1 may affect other software that relies on the newer version. It’s possible that some applications may not function properly or may encounter compatibility issues. It’s important to carefully consider the implications and potential impact on your system before proceeding with the downgrade.
Yes, an alternative solution is to try installing npm using a different package manager, such as
nvm (Node Version Manager).
nvm allows you to manage multiple versions of Node.js and npm without requiring system-level package installations. This can help avoid dependency conflicts and the need for downgrading
