KDE Linux is the operating system the KDE project is currently working on. It 's already available to try in virtual machines , allowing you to see how it works and all the new features they're adding. However, it's far from stable, and you might encounter problems. For example, Discover can get stuck checking for updates and not complete the process, making it impossible to update the system or programs. Well, not quite impossible.
The terminal is used extensively in Linux. It's not necessary for most tasks, but it's often useful for troubleshooting. When the KDE Software Center isn't working, you can use ` sudo apt update` in Kubuntu , and DNF in Fedora, but immutable systems are different. In some, `sudo` isn't even available by default, but in KDE Linux it is, and you can update the system with it.
Update KDE Linux from Terminal
The process is simple, but you need to know which command to use. As we mentioned, you can't use APT, DNF, or even Arch's Pacman (the system KDE Linux is based on). You have to use a different command:
sudo systemd-sysupdate update
If we've never used sudo before, it will warn us of the dangers. Linux users already know what can happen (we can basically wipe out the entire system root with the right command). But in cases like updating, the risks are usually not very significant.
When the update process is complete, we can restart manually or with:
systemctl reboot
Upon restarting, the operating system will be updated.
And the programs?
KDE Linux, like most immutable distributions, gets most of its software from Flathub , from where it downloads Flatpak packages. If Discover wasn't responding, the previous command and a restart might have fixed everything. But if not, you can go to the terminal and use `flatpak update` , as usual. This will update the programs.
And that's all. It's expected that everything will work better once the system is more stable. And if it doesn't, the terminal can always help.
