Introduction
If you’ve recently upgraded from CentOS 7 to CentOS 8 and encountered an error while running the dnf update
command, you’re not alone. Many users have faced a transaction check error that disrupts the update process. In this article, we’ll explore the cause of this error and provide step-by-step instructions to fix it. By following these guidelines, you’ll be able to successfully update your CentOS 8 system without any transaction check issues.
Understanding the Transaction Check Error
The transaction check error typically manifests in the following form:
code
Error: Transaction check error:
file /usr/lib64/libgdbm_compat.so.4.0.0 from install of gdbm-libs-1:1.18-1.el8.x86_64 conflicts with file from package gdbm-1.10-8.el7.x86_64
This error occurs when the gdbm-libs
package conflicts with the gdbm
package, specifically the libgdbm_compat.so.4.0.0
file. When attempting to update your system, CentOS 8 encounters this conflict and halts the transaction check process.
Fixing the Transaction Check Error
To resolve the transaction check error and successfully update your CentOS 8 system, you can follow these steps:
Remove Conflicting Package
The first step is to remove the conflicting gdbm
package. Open your terminal and execute the following command:
code
sudo dnf remove gdbm-1.10-8.el7.x86_64
By removing the old gdbm
package, you eliminate the conflict that is causing the transaction check error.
Install Updated Packages
Next, you need to install the updated gdbm
and gdbm-libs
packages. Use the following command:
code
sudo dnf install gdbm gdbm-libs --best --allowerasing
This command ensures that the latest versions of both packages are installed on your system. The --allowerasing
flag allows the removal of conflicting packages during the installation process.
Update Your System
Now that the conflicting package is removed and the updated packages are installed, you can proceed with the system update. Run the following command to update your CentOS 8 system:
code
sudo dnf upgrade
This command fetches and installs the latest updates for your system, ensuring that it is up to date and functioning optimally.
Conclusion
By following the steps outlined in this article, you can successfully resolve the transaction check error encountered during the dnf update
process on your CentOS 8 system. Removing the conflicting package and installing the updated versions of gdbm
and gdbm-libs
will allow you to proceed with the system update without any issues.
Keeping your CentOS 8 system up to date is crucial for security and performance reasons. By addressing and resolving this transaction check error, you can ensure that your system remains stable and secure, benefiting from the latest updates and improvements.
