New install of SDR VHF 4.1.0
#11
Hi everyone,

I had the same problem and solved it as follows:

1. Assemble the following file: https://github.com/librtlsdr/librtlsdr

2. Back up the old file: `sudo cp /usr/lib/aarch64-linux-gnu/librtlsdr.so /usr/lib/aarch64-linux-gnu/librtlsdr.so.bak`

3. Copy the new file to the old directory: `sudo cp /usr/local/lib/librtlsdr.so /usr/lib/aarch64-linux-gnu/librtlsdr.so`

After that, the GUI started as usual.

I hope this helps someone.
