how to remove and reinstall apt package manager

[filiprybar]

I have problems with my apt and i want to reinstall it. Can somebody help me please?

I do not think that apt can be removed so that it can be reinstalled. Ubuntu is built on the Debian Linux distribution and so it has inherited the Debian package management method. Please read about it.

If you tell us about the problems you are experiencing along with information about the version of Ubuntu that you are using and information about your hardware, someone on this forum might suggest what to do to fix the problems.

What issues are you actually having? Removing an application then reinstalling it removes files, then puts the same files in the same place.

because I tried to install grapejuice and whenever I use apt it sends me error message:
E: Malformed line 1 in source list /etc/apt/sources.list.d/grapejuice.list (type)
E: The list of sources could not be read.
my ubuntu version is 24.04 LTS

Ok

1. Reinstalling apt won't fix that.... at all
2. If you give the output of

cat -n /etc/apt/sources.list.d/grapejuice.list

We can advise and get the config file straightened which will solve the problem you are having

This gives me '1 deb

OK then the file is worthless. You can run

 
sudo rm /etc/apt/sources.list.d/grapejuice.list
sudo apt update

This should now be smooth

Thank you, that solved my issue.
