KDE fail to load providers.xml file

[Frank_boje]

I previously installed KDE with

sudo qubes-dom0-update kde-settings-qubes 

However, when I try to load new themes/widgets, I get an error: “Loading of providers from file: https://autoconfig.kde.org/ocs/providers.xml failed”, even though the file is available online. I also searched the web for a solution and found this: How to fix KDE Discover loading of providers failed error however I don’t see any *.knsrc files under etc/xdg/

I also don’t quite get how to run Discover from the command line, I tried with “plasma-discover”, but it doesn’t find that command.

You have installed KDE in dom0 which is not network connected.
You cannot use those tools.

You can download an archive in a qube, transfer it in to dom0 .
This is covered in the doc
Move the files in to /usr/share/plasma/desktoptheme/

Thank you for pointing on this.

I do exactly as it says, but I get a permission error for some reason. Despite reading following topics:

How to copy from dom0

Is it possible to paste into the dom0 terminal?

There are many times I would like to cut and paste. Is this possible?

Cannot copied applications from DomU to Dom0: Permission Denied

I’ve installed a package from a domU and tried to transfer to dom0 but failed, what I’ve done in dom0: sudo cat /usr/bin/(application-name) \ | qvm-run --pass-io [dom]U 'cat > /usr/bin/(application-name)' And it shows:/bin/bash: line 1: /usr/bin(application-name): Permission denied

Permission denied when trying to transfer template installer to Dom0? [solved]

Copying commands to dom0

If you are determined to copy some files to dom0 anyway, you can use the following method. (If you want to copy text, first save it into a text file.) Run this command in a dom0 terminal: qvm-run --pass-io <src-vm> 'cat /path/to/file_in_src_domain' > /path/to/file_name_in_dom0 Note that you can use the same method to copy files from dom0 to domUs (if, for some reason, you don’t want to use qvm-copy-to-vm ): cat /path/to/file_in_dom0 | qvm-run --pass-io <dest-vm> 'cat > /path/to/file_name_in_a…

I do it like so:

sudo qvm-run --pass-io personal 'cat /home/user/Downloads/Sweet.tar.xz' > /usr/share/plasma/desktoptheme/sweet.tar.xz

and I get:

bash: /usr/share/plasma/desktoptheme/sweet.tar.xz: Permission denied

What am I doing wrong here, please?

I believe only the qvm-run --pass-io personal 'cat /home/user/Downloads/Sweet.tar.xz' is running as root, while the > /usr/share/plasma/desktoptheme/sweet.tar.xz part is running as user (and not as root).

I think you can test my assumption by:

sudo qvm-run --pass-io personal 'cat /home/user/Downloads/Sweet.tar.xz' > /tmp/sweet.tar.xz
ls -al /tmp/sweet.tar.xz

I googled for “write output to file as root” and found:

How do I use sudo to redirect output to a location I don't have permission to write to?

Can any of those suggestions solve your issue?

You are quite right. Redirects will not work (simply) with sudo.

Yes, thank you very much.

I did it, extracted the file (tar.xz), triple-checked it, but the theme doesn’t appear in the System Settings of KDE. I also tried to look for “install from a file” as many suggest in other places, but I can’t find that options. Am I suppose to do something more in order for it to appear?
