I installed Eclipse via command
apt-get install eclipse.
This command completed correctly.
After this, I run Eclipse and add some configurations: Added a new URL for "Available Software Sites".
On the next step, I try removed Eclipse via
apt-get remove eclipse and install eclipse again.
And here I see a surprise: in the newly installed Eclipse, I see my old URL for "Available Software Sites".
So, I guess, that the configuration file(s) is not removed.
After this I tried different commands: something like this:
sudo dpkg -r eclipse sudo apt-get --purge remove eclipse sudo apt-get autoremove
But after I again install Eclipse I see my URL.
How I can fully remove Eclipse along with its configuration files?
