How to reinstall a component I accidentally deleted

Hi. This week, I installed MX Libretto for the first time. It worked perfectly until I felt adventurous and started installing programs I wanted and uninstalling some I didn't want. At some point, being the total amateur that I am, I must have deleted something that was important. Next time I tried to turn on the computer, it showed a message saying org.kde.plasma was missing, so it couldn't start.

If I could access the MX package program, I could install that component, but I can't do that if I can't even log in. However, I still have the bootable USB drive. Is there a way I can fix the missing part if I boot from the USB?

Welcome In

If you had made any TImeShift snapshots, then yes you could liveusb and then roll the timeshift back.

There may also be a method to 'reset' the KDE de to work, but I am not familiar enough with KDE to suggest on that one. Someone else here can I am sure.

Personally.. I'd reinstall, keeping home to keep your files.

Boot with the live usb, open "Chroot Rescue Scan" from menu, proceed , when you see the prompt:

chroot>

issue:

Code: Select all

apt-history
Then looking at the output install what's missing or install all that were removed that day etc...

Code: Select all

apt install xxx yyy zzz
Yes, no need to sudo.

Out of curiosity, can you get to the login screen, and then KDE won't start?

If so, it's an argument for having at least one more desktop environment as a backup boot option, such as lxqt or xfce (not much space required for those).

May be older installs, but recent MX KDE install don't have apt-history installed, ootb.

This should show the apt history if it's not installed (apt-history gets installed with the apt-notifier package)

Code: Select all

zgrep -EH ' install | upgrade | purge | remove ' /var/log/dpkg* | cut -f2- -d: | sort -r | column -t | more -d

That's right.
If you can then boot to a terminal screen and have a Net connection there, you should be able to install the "kde-plasma-desktop" metapackage, which at least should get the KDE GUI back up.
