Very dumb question, but I'm kinda new to Linux. Do I have to manually update that or does it just do it when I update packages and the like? I'm on Arch btw.
Then Arch is kind of a terrible choice for you. I use it (btw), but I've been using linux since 2008.
The learning curve and constant need to troubleshoot things isn't great for beginners.
EDIT: can someone explain why I'm getting downvoted? Isn't this common knowledge that Mint and other begginner-friendly distros that don't have complicated package managers and require less configuration and maintenance are better for someone who's just starting with Linux?
I myself began with Ubuntu back in '08 but nowadays use both Arch and Mint.
That's one of the reasons I chose arch. Because of the difficulty i can't take shortcuts or be lazy and have to actually learn. When I tried something like Pop_OS I definitely enjoyed it but didn't really learn anything because it was all done for me.
Arch Linux can be a bit overwhelming for newbies when trying out for the first time. Hey if you are comfortable with it then so be it. But if you have tried other friendly distros before this you can get an understanding of different package managers, arch packages, AUR etc. And to answer the question if you installed KDE through pacman or AUR helper, then it will be updated automatically when you update other packages through it.
It does it automatically.
But make sure to read the Arch news before every update, especially when it's a lot of packages. Something big like a new KDE Release might require minor manual intervention.
I've literally only read the news the 1 or 2 times there was a breaking change during an update. Blindly updating (non-AUR) has served me fine for over 10 years
Well everyone's milage may vary. I have set up informant some time ago so I'm forced to read the news on updates. But much more importantly I've ignored .pacnew files for years till it bit me in the ass when a Pam config file change broke my login so now I'm not ignoring.pacnew but merging them every update.
As the other commenter said I use a diff tool (I use vimdiff but meld probably works easiest if your not used to vim).
I do a pacdiff after every upgrade that will prompt you for all the changed files (most of the times there are none or the changes are minor) and let you compare your version and the .pacnew file. If anything changes in the syntax in a major way (which it almost never does) you will should spot these differences and be able to amend any changes you made in that way.
The example I gave was when some pam config file syntax changed and since I had a custom pam config (because of an encrypted home) it didn't update the syntax (creating a pacnew file) then I couldn't login after reboot.
I would recommend doing it manually - you can get a GUI diff tool (I like Meld), run it with both the normal file and pacnew, and merge every change from the pacnew into the main file.
There's no way you're so new to Linux that you wouldn't know if that would update automatically yet you're running Arch btw. That's like saying, "Do I need to do oil changes on my car? I built my engine, btw."
all you have to do to "run" arch is type out some lines from a YouTube video and press enter. With all the people saying "Arch! Arch!" at every corner it's totally understandable that someone would try it and still be confused on basic stuff.
Nah, there's a bunch of people (even on Lemmy) that recommend Arch or Arch-derived distributions to newbies. Many mention they haven't used any other distro themselves.
I once had someone tell me that they use Arch on there server since it is stable. If it works that is fine but don't go around telling people that Arch is more stable than Ubuntu, Rocky or Debian.
Depends. There's also the included archinstall script, which skips all of that. Just some minimal configuration you find on most distros (Language/Time Zones/Mirrors...) and that's it.
So yeah, nowadays it's totally possible to end up with a working Arch installation without knowing anything about it besides that one command.
On linux, generally everything you install is through a centralized repository, you can think of it as an app store, arch is all entirely updated through pacman, pacman is just a command line way to interact with the app store.
In general, almost everything you install with pacman will update when you do pacman -Syu (and restart, in case of kernel updates). The way packages work, all the files needed for a piece of software to function are installed from a package, and when you install a newer version, it removes all the files from the old version and puts in new ones. (Caveats apply to configuration files you can modify - those don't get replaced if you do)
So after you update some software through pacman, it should be in an entirely clean state, just like if you just installed it. The main caveats apply to things like flatpak, which manage its own packages, and software like Steam and Discord, which have an additional auto-updater for some things that's storing files separately.
With Arch pacman -Syu will do it for you. Generally you are encouraged to stick with the version in the repositories.
You can install things from source by downloading the source code, building it (eg. gcc code.c or cargo build) and then copying the binary somewhere.
Typically if you were going to install things from Source, you would write a pkgbuild for it and that would integrate it with pacman so you have a centralised manager of everything that you have installed to simplify updates and removal and conflicts etc.
Doing this for small packages is pretty trivial and sometimes necessary. For a large package like KDE plasma It is a very large undertaking and you would never do it in practise.
The maintainers package the desktop environment with a pkgbuild, test it, And then upload it so that you can use it.
Also note that when the arch maintainers do package that software they compile it into a binary so you just have to download it. You don't also have to build it.
I am not sure if anyone answered your question in a way that you were expecting so let me try
yes you will get the update but you might not know it because your config wont change, so you have to go into the theme settings and use the "default" to see the pretty
