How to cleanout any traces of a a broken package.[Solved]

[Ironfighter]

I recently installed QCAD on my system. The package worked fine when I first installed it.
I use a laptop and a second larger screen and was able to drag the Open QCAD window from my laptop on to my second screen.
However an upgrade was available (so as I had paid for the professional version) I downloaded and ran the install from a shell script after making it executable.
Unfortunately that was a big mistake. The package is now locked in full screen on my laptop and when I try to drag it to my larger screen the programme crashes.
I still have the installer for the previous version so I deleted the upgrade from my home/xxxxx/opt folder, removed the desktop icon and ran Stacer to clean up any debris.
Nevertheless since running the shell scrip for the older version I am stuck with the same display problems (which I didn'y have previously). Perhaps there is a bit of debris still on my laptop that is causing the problem?

Can someone advise me the best way to clean up any debris that may be on my system please.

Code: Select all

sudo apt purge qcad -y

or even

Code: Select all

sudo apt purge *qcad* -y

Also have a look at (from Menu) "Session and Startup" => Autostart Apps tab if there's still something there, if yes, remove/uncheck ..

You can use MX Cleanup after them .. For deeper cleaning: "Bleachbit" . (If still needed).

Thank you very much Huckleberry Finn

To clean the system I use BleachBit (I use as root).

To clean orphaned files, install Deborphan from MX Package install
When it is installed, go to Terminal and type deborphan and that will display orphaned files.

Then type
sudo orphaner

This will open a program in Terminal, it has a blue background. It will allow you to delete orphaned files.


Cleaning unnecessary files with Synaptic
In Synaptic go to Status>Installed (Local or obsolete) and 50% of the packages that you find in there can be deleted.

Also go to Custom filters>Broken You can delete broken packages that you find in this section.


Finding files hard to delete
I installed Angrysearch. It creates a database or list of every single file in your system.
You then search for the file that you want to delete and when you find it you can delete it manually.
You may need root acces to the folders for this. Make sure you only delete the relevant file as you could damage the system.

How do you know which ones can be deleted...?
