I installed eclipse using the installer from here. Then, I tried to remove everything using apt:
$ sudo apt autoremove eclipse*
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package 'eclipse' is not installed, so not removed
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
I think it will not be completely removed if I just delete the eclipse folder from my /home directory. Is there any clean and easy way to remove it?
