Ubuntu – Completely Uninstall Pycharm 3.4 from Ubuntu 14.04

Like yourself, I'm a PyCharm Pro user - I gained this through my opensource developments.

The PyCharm Pro download is much larger than the community edition - this indicates that the extras bundled with Pro don't exist in the community edition. Hence - to gain the benefit of the Pro, you basically uninstall the community and reinstall the new version.

Its tidier to do it this way rather than untar'ing over the community install.

The only minor gotcha was that my local community installed edition created an icon desktop file in ~/.local/share/applications - this conflicted with the Pro version. Hence, you'll need to remove the local file first before the Pro version is recognised.

Viber is available as a .deb package and also as tarball. If you installed viber through the .deb package, then you can easily uninstall it using sudo apt-get remove viber

But instead, if you installed through the tarball, then you must have extracted the viber files into a single folder such as /opt/Viber. Just delete that folder and any .desktop files (shortcuts) that you created for it.

In addition, Viber user configurations are stored in ~/.ViberPC. You can choose to delete that as well. Note that if you do this, the next time you install viber, you would have to make any customization you made this time , again.
