Ubuntu – How to completely uninstall eclipse

I had exactly the same problem today. First, a little googling brought me to your issue (didn't assumed to be due to OpenJDK). After a little more research, finally solved this strange behaviour: have a look at this ubuntu-bug.

So the quick solution is just to run sudo apt-get --reinstall install tzdata-java (reinstalling Time zone and daylight-saving time data for use by java runtimes)

Cheers

Some packages can't be uninstalled if some dependencies are gone, or some configuration files have been deleted for some reason. You will end up with a package that is not completely installed nor completely uninstalled.

The solution, in this case, is to sudo apt-get install the package. If necessary, do sudo apt-get install --reinstall [package]. Missing files will be added to the system, and any missing dependencies installed on the fly. Then the package can be uninstalled completely in the usual way: sudo apt-get remove [package].

If apt-get refuses to re-install the package because of other (dependency) issues, you can only use apt-get to download the package and use dpkg directly to install it:

apt-get download mysql-common
sudo dpkg -i mysql-common_*.deb
sudo apt-get install -f

Sometimes you can skip the download because Apt tends to keep an archive of previously downloaded and installed packages in /var/cache/apt/archives/ so you can start directly from the 2nd step:

sudo dpkg -i /var/cache/apt/archives/mysql-common_*.deb
