Solution

Issue

I recently installed the package kubuntu-desktop with the terminal as follows:
sudo apt-get install kubuntu-desktop

I would now like to delete but when I use the 'rm' command, the following message appears:

xxxx@xxxx-laptop:~$ sudo rm kubuntu-desktop 
rm: can not remove 'kubuntu-desktop':.....

Solution

You must understand the use apt-get or rm.

apt-get allows you to manage packages and dependencies. It is accompanied by a wide range of command him to do his job.
To uninstall a package, we use apt-get:
sudo => to do as administrator
apt-get => ask for apt-get to do
remove => remove
kubuntu-desktop => the package to remove
- ```
sudo apt-get remove kubuntu-desktop
```
rm is a command to delete files or folders. For example I want to delete the test.txt file stored at the root of my personal file:
- ```
rm /home/username/test.txt
```
to delete the xxx file in the same location:
- ```
rm -r /home/username/xxx
```
