Questions
Here are a few questions and thought experiments that you may ponder, some based on the skills you have learned in this chapter, and others revealed in later parts of the book:
- My Linux workstation is running low on disk space. How do I uninstall or remove applications that I don't use anymore?
Hint: Software packages installed with GUI package management tools can be uninstalled from the same GUI (for instance, see Figure 1.36). Others can be removed using the package manager CLI tools (for instance,
apt,dpkg, andrpm). - If I had a relatively large number of Linux VM instances or distros deployed and running at the same time, how would I make it easier to manage them?
Hint: Use Vagrant, a tool for building and managing VM environments.
- How do I enable multiple GUI desktops (GNOME, KDE) for different users on the same Linux system?
Hint: In the Installing Linux graphical user interfaces section, we showcased the addition of KDE side by side with GNOME. Each user can log in with their GUI desktop of choice (see Figure 1.31).
- I'm looking for a robust email client and team collaboration solution for my Linux workstation.
Hint: The Additional software packages section may provide some guidance.
- Can I run multiple Linux instances in WSL?
Hint: Yes. Use
wsl --import. - How do I upgrade my Linux machine to a new version of the distro?
Hint: Create a bootable media of your new Linux distro and run the installer. Choose to upgrade when prompted. You may also use the command line. Check out the related CLI tools for your Linux distro (for instance,
do-release-upgradefor Ubuntu).
