[Post-Install] Kubuntu 25.10 minimal fail to install

[deadsplash]

When I try to install Kubuntu minimal in a VM show this error in the finals steps of the installation wizard. The installation fail but the OS boot ok.

LibreOffice, KDE Games, Haruna Player are installed in the minimal version.

If the OS boots and runs successfully, then the installation didn’t fail. The message just informs that the indicated packages couldn’t be removed, which is correct as you performed a minimal install.

The list of packages of the error are packages that in the minimal install don't have to be installed. The minimal version of Kubuntu is without browser, LibreOffice and multimedia players and other KDE apps. The install fail to remove these packages.

The Minimal option actually uninstalls packages. The installation process involves writing an image of the OS to the disk, not installing individual packages. The minimal option uninstalls packages after the general install has completed.

This is what failed. You can find the list of packages on the installer thumbdrive at /etc/calamares/modulespkgselect_context.conf. You can use this as a basis to try to uninstall these using apt.

To remove the native packages:

sudo apt-get --purge remove kmahjongg kmines kpat ksudoku skanlite skanpage okular libreoffice* kdeconnect krdc konversation neochat elisa haruna vim snapd partitionmanager usb-creator* plasma-welcome kde-config-tablet plasma-welcome


sudo apt-get autoremove​

I will imagine that it may be necessary to remove any snaps installed (firefox for example) beforehand, but it might work without doing so -- it will complain if you do need to.


Or try a new install, and see if it works this time, but click the icon on the bottom right of the progress bar to see the output, so you can copy what the actual error is if it happens again.
