This OS is running on a Precision 5820 Tower with 64G of memory
I’m new to linux, having used MS products since DOS 2.0. My new linux system is working fine and I’m learning alot, but still need more. My system has nautilus file manager and I know how to use it. Recently I have been investigating other file managers like XFE and Krusader. Decided to try Krusader, but for some reason can not get it to install. Here is what I have done so far.
sudo apt update
sudo apt-get install krusader
Received the error ‘unable to locate package krusader’
Next tried
lsb_release -a
No LSB modules available
Distribution ID: ubuntu
Description: ubuntu 24.04.3 LTS
Release: 24.04
Codename: Noble
Next I looked for krusader package in 24.04 and found it
Noble(24.04LTS) utils: Twin panel (Commander-style) file manger [universe] 2:2.2.1-0ubuntu: amd64 arm64 armhf ppc64el riscv64 s390x
Next I looked at packeages.ubuntu.com and found the krusader package and downloaded the amd64 copy
Now the App center on my OS sees the krusader. I click on it and it askes for my permission. After saying OK, nothing happens.
I have krusader_2.8.1-0ubuntu3_amd64.deb file in my downloads directory. Clicking on this file opens the App Center, but I can not install it. Lost any help? Thanks, Mike
Please open Software & Updates.
Make sure all repositories are ticked (no need for source code).
sudo apt update && sudo apt install krusader
Note: This is the same as running the two commands one after the other. It should work. If it doesn’t you have serious issues. The package is in the official repository for sure.
PS - Keep in mind the software you want to install is part of KDE. Installing it in vanilla Ubuntu will pull and install lots of KDE dependencies. Probably for no good reason, but you do you…
I’m not sure what features you’re looking for in krusader, but if you’re wanting a twin panel file manager, then I’d check out gnome-commander. It’s a gnome program so obviously it’ll fit in better with the gnome desktop and you won’t be installing a portion the KDE desktop environment.
i installed inxi, then ran it, this is the result.

Do not understand what it means.
Which krusader gave these results, nothing, just gave a new command line prompt.
I’m not sure a completely understand the environment. I know I have GNOME and that krusader was made for KDE. The ubuntu 24.04 LTS is my first experience with linux. Is KDE an OS? or is it just a GUI that can be used with ubuntu? I’m pretty green with ubuntu. Done some reading, but still need to know more. Thanks for the help, Mike
The most likely reason you are experiencing issues is because you are set to only receive security updates but not updates from the main noble repositories.
Go to Software & Updates >> Updates and check that it is set to subscribed to all updates.
I can’t really improve upon what Google returns for “What is KDE”
KDE (K Desktop Environment) is a popular, free, open-source software project that provides a customizable graphical interface (desktop environment) for Linux and Unix-like systems, built around the powerful Qt toolkit, with its main component being the KDE Plasma desktop, known for its flexibility, extensive settings, and integrated suite of applications like Dolphin file manager and Krita painting software, often seen as a powerful alternative to Windows or GNOME.
That’s it in a nutshell. Lot’s of other stuff goes into it, but for a new user just knowing that its the set of programs, services, and libraries that presents the user with a graphical desktop and a set of useful applications is a good starting point. The nuts and bolts of how it all works together are advanced topics.
The reason you should be cautious about mixing applications belonging to one desktop environment (DE) with another is that their dependencies may be installed which can lead to duplication of functions and possible conflicts with another DE’s programs and services that run in the background.
It is possible to install more than one DE on your system, but a user should be aware of the potential pitfalls of doing so. I wouldn’t recommend it for a new user.
I installed ubuntu from a ISO
Looking at Software & Updates, I have it set to display immediately for both security and others.
Here is what update responds
Hit:1 http://security.ubuntu.com/ubuntu noble-security InRelease
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
All packages are up to date.
Nautilus works, but I’d like something better. Looked at a few file managers that were listed as would work with ubuntu. I downloaded the krusader manual and I liked what it can do. Mike
I’m a little of a control freak and do not like automatic things, so I checked never for automatic updates. I figured that if I had display immediately, I could check what is being updated and then decided whether or not I wanted it. Could this be stopping the update? Mike
I also noticed that subscribe to is dimmed out and I can not change it the All Updates shown in yours.
No, I did not enable ubuntu pro. Was unsure what it really was. Did a little reading and it seems that pro extends the life of the current OS that I have. It mentions an open source repository, which I thought was already available with ubuntu. And a few other items that I was not really interested in, but maybe should be? Before I enable it I want to do some more investigation, Thanks for the tip.
I did the pro status and this is want the results were
SERVICE AVAILABLE DESCRIPTION
anbox-cloud yes Scalable Android in the cloud
esm-apps yes Expanded Security Maintenance for Applications
esm-infra yes Expanded Security Maintenance for Infrastructure
fips-updates yes FIPS compliant crypto packages with stable security updates
landscape yes Management and administration tool for Ubuntu
livepatch yes Canonical Livepatch service
realtime-kernel yes Ubuntu kernel with PREEMPT_RT patches integrated
usg yes Security compliance and audit tools
For a list of all Ubuntu Pro services, run 'pro status --all'
This machine is not attached to an Ubuntu Pro subscription.
See https://ubuntu.com/pro
To date these services are unknown to me. May have to investigate what they really are.
Rubi, I understand that some people are sensitive about recommendations and those that are presented in text form can be taken different ways. I’ll be 80 years old soon and have been yelled at by the best, which has hardened me quite a bit. I appreciate your help.
When I set the ‘Auto check for updates’, to NEVER, I figured that this affected only the checking process and that the ‘Display Immediately’ would inform me. BUT maybe that was not a correct assumption?
I can change this and retry the krusader install.
Lastly, I was unaware of noble and noble-updates, where and why they need to be enabled.
Again, I appreciate the help, because I’m greener than a dollar when it comes to linux. Thanks, Mike
Well… I got the Krusader to install and it works fine. I changed the Software settings for updates, but that didn’t do it. What did the trick was, for some reason on the ubuntu software tab all the options ‘downloadable from the internet’ were not checked. I keep a notebook of all the things I do with ubuntu, (my memory is not that good) and I either did not write down that I changed this or it was not checked to begin with. Anyway, it works not and I learned a little. Thanks for the help.
