System: Ubuntu 22\_10 (kinetic)  
Python: python3/kinetic,now 3.10.6-1 amd64  
Driver: gr-limesdr/kinetic, 3.0.1-4build1 amd64  
LimeSuite: limesuite/kinetic 20.10.0+dfsg-6 amd64  
GnuRadio: gnuradio/kinetic,now 3.10.3.0-4 amd64  
Radio: LimeSdrMini 2.0  
Other: Many some other packages

Hello,

there is a hard way, to get the LimeSdrMini2.0 running with GnuRadio and Ubuntu.  
I’m trying this now some days with no success.  
After I’m running into some installation mistake/fault/errors  
the installation seems to be correct.

In GnuRadio I have only a smal flowgraph with  
_LimeSuiteSource(RX)_ and _QT GUI Frequency sink_ blocks.

But with this, I get a runtime errror:  
Traceback (most recent call last):  
File “/home/user/TestLimeSdrMini2\_0.py”, line 37, in   
import limesdr  
File “/usr/lib/python3/dist-packages/limesdr/ **init**.py”, line 18, in   
from .limesdr\_python import \*  
ImportError: generic\_type: type “sink” referenced unknown base type “gr::block”

> > > Done (return code 1)

I’m not sure, if this is a LimeDriver, Python, GnuRadio or installation problem…  
(LimeUtil, LimeSuiteGUI and LimeQuickTest work well)

Any hints are welcome  
Karlheinz

This type of error usually means that you have more than one version of python installed and that the version being called cannot find what is installed under a different version -

```auto
sudo find / -name "*dist-packages*"

```

will show if there is more than one version installed.

Hello,  
there was only Python3.10 installed.  
Therefore I have setup my system completly new with the above listet modules.  
Now I can start GnuRadio without errors, but it produces no signal:

## Generating: ‘/home/user/MyTest.py’ Executing: /usr/bin/python3 -u /home/user/MyTest.py Warning: Ignoring XDG\_SESSION\_TYPE=wayland on Gnome. Use QT\_QPA\_PLATFORM=wayland to run on Wayland anyway.

But there is still a discrepancy between the gr-limesdr drivers:  
Installed 3.0.1-3, used 2.2.7.  
I think, this is a mistake in the installation procedure/sequence.  
I will further look at that…

If you do the build from source, It sometimes helps to force the install location with cmake -

```auto
git clone https://github.com/myriadrf/gr-limesdr.git
cd gr-limesdr
mkdir build
cd build
cmake ../ -DCMAKE_INSTALL_PREFIX=/usr
make
sudo make install
sudo ldconfig

```
