In this article, we will delve into the process of installing the Deepin Desktop Environment (DDE) in Ubuntu 20.04, and how to resolve the qtbase-abi-5-9-5 package dependency error.
To install Deepin DE in Ubuntu 20.04 and resolve the qtbase-abi-5-9-5 package dependency error, you need to remove any existing PPAs related to DDE, add the correct PPA from the UbuntuDDE team, update your package list, and install the ubuntudde-dde package. If you still encounter the package dependency error, it may be due to an outdated system or conflicts with other PPAs, so it’s recommended to update your system and remove any conflicting PPAs.
Introduction
Deepin is a beautiful, easy-to-use, and reliable operating system. Its desktop environment (DDE) is much appreciated for its design and user-friendliness. However, installing it on Ubuntu 20.04 can sometimes lead to a package dependency error, specifically qtbase-abi-5-9-5. Let’s walk through the installation process and how to resolve this common issue.
Preparations
Before we begin, it’s crucial to remove any existing PPAs related to DDE to avoid conflicts. We will use ppa-purge for this. If you don’t have ppa-purge installed, you can install it using the following command:
sudo apt-get install ppa-purgesudo is a command that allows you to run programs with the security privileges of the superuser. apt-get is the package handling utility (i.e., installer) in Ubuntu. The install parameter tells apt-get what we want to do.
Once ppa-purge is installed, you can remove the DDE PPA with the following command:
sudo ppa-purge ppa:leaeasy/ddeppa-purge will disable the PPA and downgrade any packages you’ve installed from it to their versions in the official Ubuntu repositories.
Adding the Correct PPA
After removing the old PPA, we will add the correct PPA from the UbuntuDDE team. This can be done with the following command:
sudo add-apt-repository ppa:ubuntudde-dev/stableadd-apt-repository is a script which adds an external APT repository to either /etc/apt/sources.list or a new file in /etc/apt/sources.list.d/. The ppa:ubuntudde-dev/stable is the PPA we are adding.
Next, update your package list with the following command:
sudo apt-get updateThe update command is used to resynchronize the package index files from their sources via Internet.
Installing the Deepin Desktop Environment
Now that we have the correct PPA added and our package list updated, we can install the DDE packages. This can be done with the following command:
sudo apt-get install ubuntudde-ddeThe install command is used to install the package, and ubuntudde-dde is the package we want to install.
After the installation is complete, you can log out and select the DDE session from the login screen.
Resolving the qtbase-abi-5-9-5 Package Dependency Error
The qtbase-abi-5-9-5 package dependency issue is a common error that arises during the installation of DDE. This issue should be resolved by using the UbuntuDDE team’s PPA (ppa:ubuntudde-dev/stable) instead of the ppa:leaeasy/dde PPA.
If you still encounter this issue, it may be due to an outdated system or conflicts with other PPAs. In such cases, it’s recommended to update your system and remove any conflicting PPAs.
Conclusion
Installing the Deepin Desktop Environment on Ubuntu 20.04 is a straightforward process if you know the correct steps. By using the correct PPA and resolving any potential package dependency issues, you can enjoy the beautiful and user-friendly DDE on your Ubuntu system.
Remember, always be cautious when adding PPAs and installing packages from external sources. Always use trusted sources and keep your system updated to avoid potential issues.
