In this article, we will be discussing how to fix unmet dependencies when installing Microsoft SQL Server 2019 on Ubuntu. This is a common issue faced by many users, and we’ll provide a step-by-step guide to help you navigate through this process.
Microsoft SQL Server is a relational database management system developed by Microsoft. It is widely used in both small and large scale applications for data storage and retrieval. However, while installing SQL Server 2019 on Ubuntu, you might encounter an error related to unmet dependencies. This typically happens when the system cannot find or install a package that SQL Server needs to function properly.
Understanding the Error
The error message you might encounter during installation could be something like this:
The following packages have unmet dependencies: mssql-server : Depends: libldap-2.4-2 but it is not installable. This message indicates that the package
libldap-2.4-2 is required by SQL Server, but the system is unable to install it.
Step 1: Check Package Availability
First, you need to check if the
libldap-2.4-2 package is available in the official Ubuntu repositories. This can be done by running the following command in your terminal:
apt search libldap-2.4-2
This command searches for the
libldap-2.4-2 package in the available repositories. If the package is not found, you will need to find an alternative source or repository for this package.
Step 2: Enable Additional Repositories
If the required package is not available in the official repositories, you can enable additional repositories that might have it. This can be done using the
add-apt-repository command. Here is an example:
sudo add-apt-repository universe
sudo apt update
add-apt-repository command adds a new repository to your system. In this case, we are adding the ‘universe’ repository, which contains community-maintained free and open-source software. The
apt update command updates the package lists for the repositories you have enabled.
Step 3: Resolve Broken Packages
If you’re still facing the same issue, it could be due to broken packages on your system. To fix this, you can run the following command:
sudo apt --fix-broken install
This command attempts to correct a system with broken dependencies in place. It does this by downloading and installing the missing packages or by uninstalling the packages that are causing the conflict.
Step 4: Remove Conflicting Packages
If none of the above steps work, you might need to remove any conflicting packages that are causing the issue. This can be done using the
apt remove command as shown below:
sudo apt remove <package-name>
<package-name> with the name of the conflicting package. After removing the conflicting packages, try to install SQL Server again.
Step 5: Seek Community Support
If you’re still unable to resolve the issue, consider seeking help from the Ubuntu community. Websites like Ask Ubuntu or Stack Exchange can provide further assistance. Remember to provide detailed information about your issue, including the error messages and the steps you have already taken.
While this guide should help you resolve the unmet dependencies issue when installing SQL Server 2019 on Ubuntu, it’s important to note that Ubuntu 22.04 is not a stable release at the time of writing, and compatibility issues with certain packages may arise. Always ensure that you’re using a stable and supported version of your operating system when installing critical software like SQL Server.
Microsoft SQL Server is a relational database management system developed by Microsoft. It is used for storing and retrieving data in various applications.
Ubuntu is a popular open-source operating system based on the Linux kernel. It is widely used for desktops, servers, and cloud computing.
Unmet dependencies occur when the system cannot find or install a package that SQL Server requires to function properly. This can happen if the required packages are not available in the repositories or if there are broken or conflicting packages on the system.
You can use the
apt search <package-name> command to check if a package is available in the Ubuntu repositories. Replace
<package-name> with the name of the package you want to search for.
You can use the
add-apt-repository command to enable additional repositories in Ubuntu. For example,
sudo add-apt-repository universe adds the ‘universe’ repository, which contains community-maintained free and open-source software.
apt --fix-broken install command attempts to correct a system with broken dependencies by downloading and installing the missing packages or by uninstalling the packages that are causing conflicts.
You can use the
apt remove <package-name> command to remove conflicting packages in Ubuntu. Replace
<package-name> with the name of the conflicting package.
You can seek community support for Ubuntu-related issues on websites like Ask Ubuntu or Stack Exchange. These platforms have a community of knowledgeable users who can assist you with your problem.
