Re: [Discuss-gnuradio] Unable to install GNU Radio

[Prabhat Kumar Rai]

Hi Christopher,

As per the suggestion Mr Marcus gave, you can try that too. but before
doing that make sure that you completely remove the gnuradio-uhd file
from the pybombs prefix as you may again get the same error.

Also if you don't want to go to Marcus's way then you can try one more
thing which I suggest:
1) Completely remove(uninstall) pybombs file and folder.
2) Use locate command and search for uhd file and delete it. As per
the error which you gave it seems there exist other uhd files already
in the system.
3) Be cautious on step 2, make sure you don't delete any important
library or other files.
