Kubuntu 26.04
Krusader not available, Discovery doesn’t find it.
link from https://apps.kde.org/en-gb/krusader/ open Discovery, but no Krusader either.
How to install it ?
Command line should work fine.
sudo apt install krusader
I don’t generally use GUI tools for installs and package management. I’m using Ubuntu stonking - but anyway krusader appears to be in the archive universe packages.
sudo apt-cache policy krusader
krusader:
Installed: (none)
Candidate: 2:2.9.0-2build2
Version table:
2:2.9.0-2build2 500
500 http://us.archive.ubuntu.com/ubuntu stonking/universe amd64 Packages
Does anyone know if Discover queries archive universe packages ?

It’s in the universe repo. If you run:
sudo add-apt-repository universe
sudo apt update
sudo apt install krusader

yep. that works.
Quite often I use Discovery, cuz I can see if the app is in apt repos, flatpak or snap - in one place.
anyway, sounds like a Discovery bug ? or Kubuntu ?
Just needed the extra package source enabling

yes, from apt cli it worked. (i didn’t have to add anything) or synaptic
but also Discover has those repos (and it doesn’t find Krusader 
)
Just as an aside on my Ubuntu 24.04 machine,Software (gnome-software) also does not find Krusader but it is installable via cli and synaptic.

Both gnome-software and discover do not work with individual packages - they work with applications defined by the AppStream metadata. There is no 1-to-1 relation - one application may consist of multiple packages (and theoretically one package may provide metadata for multiple applications).
No metadata is defined for Krusader, so it is “invisible” to any tool that works with AppStream information.
Available applications provided by the defined repositories are in the /var/lib/swcatalog and metadata for applications defined by the installed packages is in the /usr/share/metainfo.
This is why so many prefer synaptic.

And also why users should use the command-line….. sorry I’m just an old unix geek yelling at young whippersnappers.

because… that’s the way … 
yes, my post is exactly about it, Discover comes with KDE and Kubuntu, but, doesn’t work as expected.
with kubuntu 26.04 I see even “a regression”, before there was only Discover, now there is an icon 'manage software" and you can choose …
it doesn’t make it easier, but more complicated…
I use CLI to advise as this is a text based interface… a forum. So I use CLI so commands can be copied and pasted. Super easy and very logical
