[CONFIGURATION] Package failed to install

[stuarte]

Hi,
I'm trying to install packages using Discover. For each package I click on the "Install" button. Each package reaches the 99% point in the install process and then the message shown in the title above is displayed. Also, the "Install" label on the install button changes to "Remove". Further, the packages don't show up in the appropriate subsection of the Application Launcher. For example, both QtCreator and KDevelop don't show up in Applications/Development and Fritzing doesn't show up in Applications/Electronics. Lastly, when I examine the "Installed" section within Discover, I see that Fritzing, KDevelop, and QtCreator are all listed as installed with each package having a "Remove" button.

Is there something that I'm missing here ?

Any help would be very much appreciated.

Best regards,

Stuart

You could try it from the command line and see if you get more meaningful info.
For example, what do you get if you type
sudo apt install fritzing
?

Run:

kdevelop

and tell us if it ever opens the KDevelop IDE.

If you don't insist on using Discover: I have installed KDevelop on two computers with apt in Konsole recently and it did show up in K-Menu / Applications / Development afterwards…

PS: Try running kbuildsycoca5 in Konsole, this should rebuild the K-Menu entries - perhaps it helps with your problem…

Hi Schwarzer Kater,

I tried running kbuildersycoca5 in Konsole and received the following reply.

kbuildsycoca5
kbuildsycoca5 running...
kf5.kservice.sycoca: Parse error in "/home/kub/.config/menus/applications-merged/xdg-desktop-menu-dummy.menu" , line 1 , col 1 : "unexpected end of file"

Do you have any idea what this means and how I can correct it ?

Best regards,

Hi kyonides,

I ran kdevelop in Konsole and two things happened in an interleaved manner. First the response shown below was displayed.

Part way during the displaying of the response shown above, the KDevelop IDE did(!) open, in a somewhat reduced size. When I closed the IDE the system generated the following response.

register count: 0, destroy count: 0

WRT the Git and Perforce plugins, I opened KDevelop, selected Settings/Configure KDevelop/Plugins and enabled both Git and Perforce plugins. It then turned out that I had to use Discover to installed the Git package that had the same icon as the KDevelop plugin. This enabled the Git plugin within KDevelop. Discover could not find any package for Perforce.

This is as far as I have got. Any suggestions/advice you may have would be very much appreciated.

Best regards,

Stuart

I've had some success installing with Discover, but it's inconsistent. So I stay away from it specifically for installing software. But it is good for FINDING software, mostly.

I only use synaptic, muon, or apt for actually installing.

Honestly I don't and can only guess.
I would move the complete contents of $HOME/.config/menus to e.g. the desktop, logout and -in, see if and what has happened and run kbuildsycoca5 again. You can always copy the contents back again, if the need occurs.
My $HOME/.config/menus folder contains one file only: applications-kmenuedit.menu, which contains the changes I have made manually by right-klicking on the K-Menu and editing the entries…
