Google Earth

Google Earth gives you an annotated eagle's eye view of our planet. This is a free proprietary package (you must accept the license to use this package).

sudo apt-get install googleearth-package
make-googleearth-package --force

Doubleclick on the resulting .deb file.

-- or --

To install the latest Linux binary, download and save the GoogleEarthLinux.bin package from Google Earth downloads. Then install:

chmod +x GoogleEarthLinux.bin
./GoogleEarthLinux.bin

Run:

Applications -> Internet -> Google Earth 3D planet viewer

You should turn off the Google Earth -> View -> Atmosphere setting, or you might see clouds everywhere and the ground won't show up.

Troubleshooting

If Google Earth opens, shows the splash screen, and then crashes, you’re probably experiencing a common issue. Running ~/google-earth/googleearth in a terminal will show this error: ./googleearth-bin: relocation error: /usr/lib/i686/cmov/libssl.so.0.9.8: symbol BIO_test_flags, version OPENSSL_0.9.8 not defined in file libcrypto.so.0.9.8 with link time reference

To fix this, browse to the folder you installed Google Earth into. By default this will be google-earth in your home folder. Find the file libcrypto.so.0.9.8 and rename it to something else, like libcrypto.so.0.9.8.bak. Google Earth should now start correctly.

cd ~/google-earth
sudo mv libcrypto.so.0.9.8 libcrypto.so.0.9.8.bak
sudo ln -s /usr/lib/libcrypto.so.0.9.8 ~/google-earth/libcrypto.so.0.9.8

(Note: You can also specify /home/user/google-earth instead of ~/google-earth ).

For other issues, see the Ubuntu help pages on Google Earth.

Uninstall Google Earth

To uninstall run the uninstall shell script located in the /home/user/google-earth folder (or whichever folder you installed google-earth into).
