Endeavour didn’t provide discover ootb. If you want to using it, the package is in the repo.
sudo pacman -S discover packagekit-qt5
Please take not that its not recommended to using it for updating the system, since he can soft-lock pacman. Personally i’m using it only for kde modules and Flatpak. For that you need to upgrade your system before (you can also pick the good one but the first option is easier).
Yes It is, Other Distros have it hooked up, although it is know to be buggy/ and I know
this from experience from my previous distro.
As far as removing it I cant be bothered its still sitting there, EOS is know as the terminal
centric distro pacman yay or paru are your friends.
In reference to the discover icon, thanks for pointing out, we are aware of the issue and would like to address it at some point in the future.
In reference to issue of the GUI package managers, our stance is clear and is stated in several previous blog posts.
We don’t ship a GUI package manager by default. This is partially because all the currently available options create support issues. However, if any individual wishes to use such a tool, they are more than welcome to do so. They are easily installed and we don’t oppose this any way.
We also include a GUI tool called EOS Quickstart which makes it easy to install a list of commonly used packages arranged by category.
However, this issue has been discussed endlessly to death and I don’t think we need to rehash it all again.
