You have to remove libraries that you have installed from source before using the PPA. If you need further help, please don't use the bug tracker but follow the instructions here: http://gqrx.dk/user-support

@csete did you get this resolved? I have an identical issue and I installed fresh (so, no previous drivers)

Manually removing librtlsdr.* files in /usr/local/lib, then reinstalling as described by @ikizhvatov's link helped.

is it in a different folder in ubuntu 16.04?

Finally gave up and removed all traces of rtl_sdr

wish it could work again ......

side question ,.... what version of gnu-radio/ofscom do you need to go back to to get the lime to quit shutting down after start?

[olealgoritme]

i did the following on my RPI3: sudo make uninstall in the rtl-sdr/ folder (from manual install) sudo apt-get purge rtl-sdr sudo apt-get -f install rtl-sdr sudo ldconfig

Any of these didn't help here. DietPi is the distro. I had everything working, the hassle started when I installed rpitx
